The Ordinary Mandelic Acid 10% + Hyaluronic Acid

The Ordinary Mandelic Acid 10% + Hyaluronic Acid is a gentle AHA serum designed to exfoliate, refine texture, and boost hydration while minimizing irritation.

This lightweight, water-based serum pairs 10% mandelic acid — an alpha hydroxy acid with a larger molecular size — with hyaluronic acid and Tasmanian pepperberry extract to deliver gradual exfoliation, moisture support, and a calming effect. Because mandelic acid penetrates the skin more slowly than many other AHAs, it can offer visible improvement in clarity, tone, and texture with a lower risk of sensitivity, making it a popular choice for those seeking effective resurfacing without aggressive irritation.

How does this serum improve skin clarity and texture?

Mandelic acid works by gently loosening the bonds between dead skin cells on the surface, encouraging natural renewal over time. The 10% concentration is intended to provide noticeable results while remaining accessible to many users, especially when introduced gradually.

• 10% mandelic acid for chemical exfoliation and smoother skin.
• Larger molecular size slows penetration for milder action versus some other AHAs.
• Regular use can reduce appearance of uneven texture and dullness.

Will it dry out or hydrate my skin?

The formula includes hyaluronic acid to draw and retain moisture during exfoliation, helping to counter common AHA-related dryness. This water-based serum supports hydration while promoting cell turnover, so the skin feels less tight than with harsher exfoliants.

• Hyaluronic acid attracts moisture for smoother, plumper-feeling skin.
• Water-based vehicle reduces heavy occlusion and residue.
• Best used alongside a moisturizer for optimal barrier support.

Is this safe for sensitive or reactive skin?

Because mandelic acid has a slower absorption profile, many people with sensitivity tolerate it better than faster-penetrating AHAs. The addition of Tasmanian pepperberry extract helps soothe and calm the skin, though patch testing is still recommended before full-face use.

• Tasmanian pepperberry extract helps reduce potential irritation.
• Gentler AHA option compared to glycolic acid for sensitive skin types.
• Introduce gradually: start every other night and monitor tolerance.

How should I incorporate it into my skincare routine?

Apply once daily in the evening after cleansing and before heavier serums or moisturizers. Because AHAs can increase sun sensitivity, always follow morning SPF protection when using this product regularly.

• Use at night only; follow with moisturizer to support the skin barrier.
• Start with every other night, then increase as tolerated.
• Daily sunscreen is essential the day after use to protect renewed skin.

Who is this for: This serum suits anyone seeking a gentle, science-forward exfoliant that balances resurfacing with hydration—particularly people with dullness, uneven texture, or those who find stronger AHAs too irritating. It's formulated to be approachable for many skin types, including those that are sensitive, provided users introduce it slowly and pair it with sun protection and hydration.
