Build Your Routine
  • Helps reduce the appearance of wrinkles
  • Improves the look of skin texture and tone
  • Helps reveal the next layer of skin
  • Boosts vital hydration into deep layers of the skin
  • Brightens the look of discoloration

At night, the skin heals quickly, and the barrier, especially, goes through a phase of rejuvenation. That’s where you need Serum 24, a chirally-correct skincare product by Cosmedix. Most importantly, Serum 24 has zero abrasive effects on the skin. 

What wins aestheticians over is the lightweight formula that directly addresses problems like poor skin texture and skin dullness. If you are exhibiting visible signs of aging, this retinol serum for wrinkles can help reverse the process with continuous use. It is not only lightweight but also seeps easily into the skin’s layers. 

Unlike other OTC anti-aging vitamin A serum, there is no trail or residue left on the skin. Upon waking, people feel their skin is hydrated and plumped. The areas of your skin that show quick signs of fatigue usually show the best improvement after a few weeks. 

Serum 24 is a thoughtful option for anyone who wants consistent nighttime care without constant recovery days. It suits those who value progress over intensity and prefer formulas that respect the skin barrier rather than test its limits.

As part of Cosmedix’s clinical skincare products collection, Serum 24 meets professional formulation standards while still working comfortably in real, everyday routines. It integrates easily whether your regimen is minimal or more layered, making it a dependable part of long‑term skin maintenance.

This retinol serum for wrinkles is built for consistency and supporting skin night after night.

  • Fine lines and wrinkles
  • Uneven skin tone
  • Stressed skin
  • Dry, lackluster skin
1. What is Serum 24 designed to do?

Serum 24 is an overnight serum designed to support the skin’s natural renewal process. It helps improve the look of uneven texture, dullness, and early signs of aging while you sleep, taking a steady, supportive approach rather than an aggressive one.

2. When should I use Serum 24 in my routine?

Serum 24 is intended for evening use. Apply it after cleansing (and toning, if you use one) and before your night moisturizer. It layers easily with other nighttime products.

3. Is Serum 24 suitable for daily use?

Yes. Serum 24 is formulated for consistent nightly use. Its balanced, lightweight texture makes it comfortable to use regularly without it feeling heavy or overly active on the skin.

4. What skin types can use Serum 24?

Serum 24 works well for most skin types, including normal, dry, combination, and mildly sensitive skin. It’s particularly suitable for those who want gradual skin refinement without frequent irritation.

5. Will Serum 24 cause peeling or redness?

Serum 24 is designed to be supportive rather than harsh. Most users do not experience significant peeling or redness when it’s used as directed. As with any new product, patch testing and gradual introduction are recommended.

6. Can I use Serum 24 with other active products?

Yes, Serum 24 can be incorporated into routines that include other targeted products. If you use stronger actives, spacing them appropriately or alternating nights may help maintain comfort.

7. How long does it take to see results?

Results vary depending on skin condition and consistency of routine. Many users notice their skin feeling more hydrated and settled fairly quickly, while visible improvements in texture and tone typically develop with continued use over several weeks.

8. Is Serum 24 part of a professional skincare line?

Yes. Serum 24 is part of Cosmedix’s clinical skincare products range, meaning it’s formulated to professional standards while still being suitable for everyday at‑home use.

Very good!

I've been using the COSMEDIX Serum 24 Rapid Renewal Complex and I'm impressed with how effective it is! It's definitely a potent serum�I could feel a slight tingling sensation when I applied it, but it wasn't too uncomfortable. Over time, my skin looked noticeably smoother and more radiant, and even some of my fine lines seemed softer. I've also noticed that my skin tone looks more even, and I have a healthy glow that wasn't there before. I'd recommend easing into it if you have sensitive skin, maybe starting a few times a week before using it nightly. Overall, it's a strong, effective product that's great for renewing the skin and boosting radiance. Definitely worth adding to your skincare routine!

Love it!

I recently discovered and tried this brand Cosmedix and this Serum 24 Rapid Renewal Complex. I am 27 years old going to be 28 soon and I have some lines and wrinkles on my face. I've tried different products but they are still there. So I gave this product a try and I must say I'm impressed.

This serum is lightweight and absorbs very well into the skin. Also, it has great ingredients like honeysuckles, which is rich in antioxidants and it is anti-inflammatory. These ingredients help hydrate the skin and give your skin a nice radiance.

Now I've been using this serum for some time followed with other products from this brans, and I must say they do wonders. I noticed it helped reduce the appearance of some of my wrinkles, brighten my skin, improved my skin texture and tone. My skin is currently loving this drum because it is helping to minimize the appearance of my lines too!

Overall, I love the quality and the ingredients in this product because it was helped my skin so much! My skin is looking and feeling more youthful. This product was provided for promotional purposes in exchange for my honest review.

The Perfect Retinol

I'm loving the results I am getting from using the Serum 24 Rapid Renewal Complex. It is a great retinol option to add to your skincare routine, especially for someone like me who experiences dryness and irritation from retinol. I have not experienced either of those things from using this product. My skin is looking more bright and youthful already and I have received so many complements lately on how great my skin is looking. I love the design of the bottle and that it comes with a pump so that I don't squeeze out too much of the cream on accident. I like how it feels nice and smooth when applying to my face. I highly recommend this product and am loving the Cosmedix brand. *This product was provided for promotional purposes in exchange for my honest review.

Beautiful Retinoid

I recently turned 40 and I feel like my skin is starting to show some wear and tear. I have been experimenting with retinoid the last year or so to find the one I really like.
Cosmedix Renewel 24 serum might be the winner! I've only been using it for about 2 weeks, so I don't have new renewed face or anything, but I have enjoyed every night I've used it (which has been about every other night).
It feels rich but light going on and is nicely and lightly scented. The product absorbs nicely without leaving my skin dry or greasy.
I'm a sucker for products that include botanical ingredients.
The pump dispenser is convenient and dispenses a really nice amount in one pump. The packaging gives medspa vibes and it looks nice on my open shelving.
So far I have absolutely no complaints and I'm hoping by the time I get through the bottle I'll look like a more refreshed version of myself!

A great Retinol

I can't say enough good things about Cosmedix Serum 24! It's a gentle yet powerful retinol alternative that has completely transformed my skin. After just a couple weeks, I noticed a dramatic improvement in my skin's texture, tone, and overall firmness. It feels nourishing and non-greasy, and I've had zero irritation, which is rare for me with retinol products. My skin looks brighter, smoother, and more youthful every morning. I especially love how it targets fine lines and gives my face a plumper, refreshed look. This serum is a total skincare essential. If you're looking for real results without harsh side effects, this is the one to try. Absolute 5 stars!

Magic serum

I've been using COSMEDIX Serum 24 and I have to say it's one of the few retinol products that's actually lived up to its promises, especially on my mature skin. I've tried other retinols before, but they either dried me out or caused too much flaking. This one feels completely different effective but gentle.One of my biggest skin concerns is hyperpigmentation. My dermatologist actually suspected it might be melasma, and nothing I tried seemed to make much of a difference besides chemical peels until I started using this. I've noticed a visible fading of the dark patches on my cheekbones and my overall skin tone looks more even and radiant. The texture of my skin has also improved it feels smoother and more refined, and the fine lines around my eyes and mouth are starting to soften. I use it at night, and I always wake up with my skin feeling plump, hydrated, and refreshed not dry or tight like other retinol products have made me feel in the past.

Fantastic Face Serum

I've been using the COSMEDIX Serum 24 Rapid Renewal Complex for several weeks now, and I'm genuinely impressed by the results. This serum is a gentle yet effective retinol alternative, formulated with Retinol AGP Complex and hydrating lipids, making it ideal even for sensitive skin like mine.

The serum has a lightweight, silky texture that absorbs quickly without leaving any greasy residue. I use just a small amount each night after cleansing, and it layers beautifully under moisturizer. There's a very subtle scent, but it's pleasant and fades quickly.

After consistent use, I noticed smoother skin texture, refined pores, and a subtle glow. Fine lines on my forehead and around the eyes are visibly softened. My skin feels firmer and more resilient. Unlike other retinol products I've tried, I experienced no peeling, redness, or irritation�just steady improvement.

This serum is a standout if you're looking for a gentle yet effective anti-aging solution. It's a great choice for beginners or anyone with sensitive skin who still wants the power of retinol. While it's on the pricier side, a little goes a long way, and the results are worth the investment.

Great serum

Cosmedix serum 24 is a great product. I have been using this cosmedix serum for 2 weeks now. I have not been great at taking care of my aging skin as far as using renewal serums and lotions but I am for sure going to start now. This product is making my face feel rejuvenated. I am starting to get those fine lines around my eyes and in other areas on my face and I feel that this serum is giving me some moisture back in those places and taking away some of those fine lines. Cosmedix serum 24 is giving me a youthful glow again. It is making me feel more confident in my aging process. We all know it is not fun to age but if we can do it with grace then why not. I would definitely recommend this product to my friends and family who struggle the same way I do.

Loving this!

This is my first time using retinol product from this brand and I'm really loving it. I always worry when switching retinol products that my skin will have adverse reactions, however this serum has been wonderful on my skin. I definitely noticed improvement in my skin texture since I started using it about 2 weeks ago. It has a lightweight texture and formula absorbs well into my skin, making it well hydrated and plump. I have not experienced any irritation or redness while using it, however I still use it every other day. Bottle design is great, since it has an airless pump, preserving the product for longer. Overall this serum is definitely worth recommending as it's gentle and effective . My skin looks more radiant, soft, hydrated and youthful.

Gentle, yet effective.

Serum 24 is that “I woke up like this” in a bottle. I've only been using it a couple weeks, but the difference in my skin's tone and texture is already real. I have combination mature skin, so I'm always cautious with retinols, but this one hasn't caused any flaking or irritation. Instead, I'm waking up to smoother, more even-looking skin with a subtle glow. The texture is creamy, not greasy, and absorbs nicely without piling under my night cream. I've even noticed a softening around my laugh lines and an overall fresher look. If you want a gentle but effective retinol that actually delivers, this one's worth the investment.

Wonderful product

I've always put a lot of effort into my skincare routine, carefully picking out quality products to keep my skin looking young and fresh, especially relying on retinol. Lately, I found the Cosmedix Elite Serum 24 Rapid Renewal Complex, and it has really changed the way o take care of my skin. This serum is packed with cool ingredients like honeysuckle, which helps protect my skin from damage while keeping it nice and hydrated. Since I started using it, my skin feels so much smoother and looks way more glowing. It's given me a confidence boost; I'm now comfortable going out without makeup on and just showing off my natural skin. Every day, I look forward to my skincare routine because of this amazing serum. It's made taking care of my skin not just useful, but something I genuinely enjoy. I can't wait to see how it keeps improving my skin! The Cosmedix Elite Serum 24 Rapid Renewal Complex feels almost like magic in a bottle. If you're wondering whether to take the plunge and give it a try, just do it!

Smooth skin

COSMEDIX Serum 24 has quickly become a staple in my nighttime skincare routine. It goes on smoothly and feels lightweight, but don't let that fool you�this serum is powerful. After just a few weeks, I noticed my skin looked noticeably smoother and more even in tone. Fine lines around my eyes and mouth have softened, and my skin feels firmer and more hydrated. What I love most is that it delivers all the benefits of retinol without causing irritation or dryness. I've also seen a brighter complexion overall, with some stubborn dark spots starting to fade. It feels like it's helping my skin renew itself overnight, leaving it fresh and more radiant by morning. If you're looking for a retinol that's both effective and gentle, this one really stands out. I highly recommend it!

Must have!

Sharing my experience with Cosmedix Serum 24 which Contains 24% LG-Retinex, which is a proprietary encapsulation of retinol and retinal. I really like that the ingredients do not contain various harmful ingredients that only clog the skin and do not allow it to breathe and rest.
About use: after washing and toning, I apply the serum on my face, let it soak in, and only then go to bed. I use it in the evenings, it lasts the whole night, and I wake up in the morning without a feeling of tightness. You must apply a product with SPF if you decide to use the serum in the morning. The serum consumption is small and little goes long way.
Results: I noticed that the wrinkles became smaller. And fine wrinkles and fresh ones are not visible as much. The tone of my skin is fresher and evened out. The skin is smooth, soft and well-moisturized. I also noticed a slight tightening effect, it is rather cumulative from long-term and constant use of the serum - the skin became more elastic.
About the bottle: a convenient bottle with a pump dispenser. Stylish, convenient, you can take it on the go.
I would definitely recommend this serum to anyone!

Great Product

I was not familiar with this brand cosmetix at all before trying this product. I am definitely a huge fan now. This serum 24 is a wonderful product. It is jampacked with great ingredients to help with aging skin. This is a nighttime serum that you apply one to three times to start with and work your way up to every night. It does contain retinol, so be sure to put your sunscreen on when using this product. I have definitely noticed after applying this product at night time that I wake up in the morning with my skin, looking bright and more useful looking. I use this serum along with the eye cream. This product has a creamy texture and absorbs pretty quickly into the skin. It makes my skin feel very hid and moisturized. I would definitely recommend this product if you are looking to prevent and treat wrinkles.

Serum 24 is amazing

I tried Cosmedix Elite Serum 24 and I love this stuff! The serum does contain forms of Vitamin A so make sure to a sunscreen when going out in the sun after use. This serum is probably my favorite Cosmedix Elite product. It makes my skin look and feel plumped, brightened and hydrated. The difference just upon immediate application is crazy. It absorbs quickly and completely. The packaging is beautiful and very professional. It's definitely something I'd be proud to display happily. The scent is pleasant. I love the pump and the amount of product it distributes. It gives enough for each section of my face per pump so there's not a lot left over that I feel like I'm wasting. I can totally tell a difference in my skin when I do and don't use this serum. This product was provided for promotional purposes in exchange for my honest review.

I incorporated COSMEDIX Serum 24 Rapid Renewal Complex into my nightly skincare routine, and what a difference this serum has made! This powerhouse serum is clinically proven to visibly reduce the look of medium to deep lines, including crow's feet. Due to the high concentration of ingredients including 24% LG-Retinex, I apply this serum 2x a week nightly until my skin develops tolerance. I follow this serum with a moisturizer so that my skin doesn't lack hydration. The serum has helped reduce the appearance of wrinkles and has helped improve the look of my skin texture.

Love this serum

I recently discovered an incredible serum that has quickly become a staple in my skincare routine. I absolutely love a good serum, especially one that blends plant extracts with retinol, and this particular product has exceeded all my expectations.

What I find impressive about this serum is its formulation; it includes a variety of beneficial ingredients that work harmoniously to nourish and rejuvenate the skin. Many retinols can be harsh and drying, leading to irritation, but this one has proven to be gentle yet effective. I've noticed significant improvements in my skin's texture and clarity since I started using it, and I can genuinely say I can't imagine my routine without it.

Another delightful feature of this serum is the scent. The infusion of honeysuckle adds a very light and pleasant aroma that enhances the overall experience. It's refreshing to apply a product that not only feels great but also smells lovely.

Overall, I am thrilled with how well this serum performs and will definitely be incorporating it into my daily skincare regimen for the foreseeable future. It truly feels like a treat for my skin!

Serum 24 is a game changer!

Finally, a retinol/retinal product I can use without irritation! This is more of a lotion texture than a serum but it does absorb quickly with no stickiness. You should shake the bottle before use and use 1-3 pumps. I find two pumps sufficient to cover my face and neck. I did ease into the product by using it every 3 days and now use it daily with an occasional skip day to use my copper peptide serum. I have noticed with use of the Serum 24 that my skin is brighter and my texture is smoother. I have noticed some fading in some discoloration I've been fighting for some time so I'm very excited about that! This product contains a propriety encapsulation of retinol and retinal which I have NOT found irritating, unlike many other retinal products I've tried in the past. I'm just so excited to find something that's actually working! I did receive this product free as a promotion for my honest review.
