The Ordinary Lactic Acid 10% Exfoliating Serum with 2% Hyaluronic Acid — 1 fl oz, Gentle Resurfacing & Hydration

The Ordinary Lactic Acid 10% + Hyaluronic Acid 2% is a water-based exfoliating serum that resurfaces skin with gentle alpha hydroxy action while adding hydration and anti-irritant support.

This lightweight serum combines 10% lactic acid with 2% hyaluronic acid in a water-based formula designed to refine texture, even skin tone, and improve surface radiance. The composition is balanced at approximately pH 3.8 to provide effective acid activity, and Tasmanian Pepperberry extract is included to help calm skin sensitivity. It’s formulated without oils, silicones, alcohol, gluten, or animal-derived ingredients.

How does this serum improve skin texture and brightness?

Lactic acid is an alpha hydroxy acid (AHA) that gently loosens bonds between dead skin cells on the surface, promoting smoother, fresher-looking skin. At 10% concentration and a pH near its pKa, the formula aims for an effective balance of active acidity and tolerability for visible textural improvement and enhanced glow.

• 10% lactic acid for surface exfoliation and smoother skin.
• pH ~3.8 to optimize lactic acid activity.
• Water-based delivery for lightweight, non-greasy feel.

Will the hyaluronic acid and pepperberry extract affect sensitivity?

Hyaluronic acid supplies hydration to help plump and soothe skin after exfoliation, while Tasmanian Pepperberry is included as an anti-irritant to reduce potential redness or discomfort. These supporting ingredients aim to make a high-strength AHA more comfortable for dry or reactive skin types when used correctly.

• 2% hyaluronic acid for hydration and temporary plumping.
• Tasmanian Pepperberry extract to help calm irritation.
• Use gradually to assess tolerance and minimize sensitivity.

How should I use this product safely in my routine?

Apply once daily, preferably at night, to clean, dry skin and follow with moisturiser if needed. Because AHAs increase sun sensitivity, daily broad-spectrum sunscreen is essential during daytime after use and on following days.

• Use in the evening only, once per day.
• Always apply sunscreen during the day when using AHA products.
• Avoid combining immediately with other strong actives (retinoids, vitamin C) until tolerance is known.

What skin types and concerns is this serum best suited for?

This formula is targeted for those with dry, dull, uneven-textured skin seeking surface exfoliation without heavy oils. Its water-based nature and anti-irritant support make it particularly appropriate for dry or mildly reactive skin that needs resurfacing and added hydration.

• Ideal for dry, textured, or tone-uneven skin.
• Not recommended for open wounds, active inflammation, or severely compromised barrier.
• Patch-test first if you have a history of acid sensitivity.

Who is this for: The Ordinary Lactic Acid 10% + HA 2% is for people seeking a straightforward, high-strength AHA exfoliant that also hydrates and calms. Choose this if you want visible surface renewal with the convenience of a lightweight, vegan, and alcohol-free serum; avoid if your skin is actively inflamed or you cannot commit to sun protection after use.
