PHA Hydration Peel

$61.00

Peel AM/PM

Sensitivity often develops when the barrier weakens and can no longer regulate exfoliation, hydration, and environmental stress. PHA Hydration Peel fills that gap as a peel for sensitive skin that is designed to resurface gently while reinforcing comfort, making exfoliation accessible even when your skin feels reactive or easily overstimulated.

This formula comprises Polyhydroxy Acids (PHAs), which are exfoliating acids known for their larger molecular structure. They work closer to the skin’s surface, where they loosen buildup without aggressive penetration. 

The result is a hydrating exfoliant for sensitive skin that refines texture and clarity without triggering the cycle of irritation associated with traditional acids.

This peel balances renewal with replenishment, as it pairs controlled exfoliation with moisture-binding ingredients, and maintains hydration levels during and after use. Your skin feels softer, uneven areas smoothen, dullness fades, and clarity improves.

We approach exfoliation through a barrier-first philosophy, where results should never come at the cost of long-term resilience. PHA Hydration Peel aligns with that approach by supporting the skin as it renews, rather than overwhelming it.

Use it as part of your evening routine after cleansing. Apply a thin, even layer across dry skin, avoiding the immediate eye area. Allow it to sit briefly, then either leave it on or remove it, depending on your skin’s tolerance and routine. Follow with a barrier-supportive moisturizer to seal in hydration. Frequency can be adjusted based on how your skin responds, although consistency matters more than intensity.

1. What makes PHA Hydration Peel suitable as a peel for sensitive skin?

Traditional peels often rely on AHAs or BHAs that penetrate quickly and can overstimulate compromised skin. Polyhydroxy Acids (PHAs), on the other hand, have a larger molecular size, which slows their absorption, allowing for surface-level exfoliation that is far less likely to trigger irritation.

2. Is this really a hydrating exfoliant for sensitive skin?

Yes, and that balance is the point of the formulation. Many exfoliants focus only on removing dead skin, which can leave the surface dehydrated and reactive. 

This peel combines gentle exfoliation with moisture-supportive components, helping the skin retain hydration as it renews. The result is softer and smoother skin that does not feel stripped.

3. Can it help with uneven skin tone?

Yes, by removing buildup gradually and evenly, the peel enables the skin to reflect light more uniformly. Over time, areas that appear dull or inconsistent begin to blend more smoothly into the surrounding complexion.

4. Will I feel tingling or discomfort during use?

Most users experience little to no tingling, as the formula is designed to avoid triggering inflammation. If you do feel mild activity, it typically settles quickly.

5. How often should I use it?

Start with one to two times per week in the evening. If your skin responds well, frequency can be adjusted. The goal is consistency without pushing the skin into a reactive state. Overuse will not accelerate results and can, in fact, interrupt barrier recovery.

6. Can I use this alongside other active treatments?

Yes, but it should be integrated thoughtfully; avoid layering it on the same night as strong retinoids or other exfoliating acids. Alternating nights allows each product to work effectively without overwhelming the skin. This aligns with a barrier-first approach to uneven skin tone treatment.

7. Is it suitable for post-procedure or sensitized skin?

PHA Hydration Peel is often well tolerated by sensitized skin due to its gentle profile. However, immediately post-procedure skin needs guidance from a skin professional. Once the skin is ready for exfoliation again, this formula is a good option for reintroducing renewal without stress.

8. How long before I see results?

Initial improvements in texture and softness can appear within the first couple of uses. More noticeable changes in clarity and tone develop over several weeks. 

Around four to six weeks of consistent use is typically where the full effect becomes more visible, especially in how evenly the skin appears in natural light.
