PHA Gluconic Acid

PHA Gluconic Acid, known in O COSMEDICS formulations as Gluconolactone, is a next-generation exfoliating acid designed to hydrate as it gently resurfaces. As a polyhydroxy acid, its molecular structure is larger than traditional AHAs, which means it works on the skin more slowly and with far less sensitivity. This makes it a supportive choice for skins that need exfoliation without the risk of irritation or barrier disruption.

One of its most unique qualities is its strong attraction to water. Gluconic Acid pulls moisture from the air and brings it to the skin, helping soften the surface and replenish lost hydration. It also forms a protective, moisture-binding shield that helps prevent water escaping from the skin, supporting long-lasting hydration.

This dual-action nature, exfoliating and hydrating at the same time, makes PHA Gluconic Acid a smart, barrier-respecting ingredient perfectly aligned with O’s corneotherapy. It gently refines the skin, supports cell optimisation through steady renewal and prepares the skin to better absorb further functional actives.

Form, Stability & Delivery

PHA Gluconic Acid is a water-attracting, water-soluble polyhydroxy acid with excellent stability in skincare formulas.

It works harmoniously within the skin’s natural processes, supporting steady renewal with minimal irritation.

How PHA Gluconic Acid Works - Made Simple

1. Gentle Resurfacing
PHA Gluconic Acid works on the surface layers of the skin to dissolve redundant cells, revealing a fresher and smoother-looking complexion. Its larger molecule size slows its absorption, making the exfoliation experience calm and controlled.

2. Deep Hydration Attraction
When applied to the skin, it pulls moisture from the air and helps the skin hold onto it, softening dryness and improving overall hydration

3. Moisture Loss Prevention
After drawing water into the skin, Gluconic Acid forms a lightweight, invisible barrier that helps reduce moisture evaporation

4. Barrier Support & Skin Comfort
Because it exfoliates gently and hydrates simultaneously, PHA Gluconic Acid supports the skin’s barrier rather than challenging it, making it suitable for delicate, dehydrated or more sensitive skin types.
