The Ordinary Lactic Acid 10% + Hyaluronic Acid 2% Exfoliating Serum

What it is and the need it serves

The Ordinary Lactic Acid 10% + Hyaluronic Acid 2% is a high-strength exfoliating serum designed to smooth texture and brighten the complexion. It combines a 10% lactic acid exfoliant with 2% hyaluronic acid to help with surface refinement and hydration as it works. Tasmanian Pepperberry extract is included as an anti-irritant to support sensitive skin during exfoliation.

How it works in practice

On the skin, lactic acid helps dissolve dead skin cells, which can lead to a more even tone and a more radiant look over time. The accompanying hyaluronic acid helps retain moisture, reducing the typical dryness you might associate with acids. Because this is a nightly treatment, it’s important to build a routine around it—start with a lower frequency if you’re new to acids and always apply sunscreen the next day to protect newly exfoliated skin.

Pros that stand out

• Clear, single-purpose formula aimed at smoother texture and brighter skin.
• High concentration of lactic acid for noticeable exfoliation on the surface.
• Hyaluronic acid adds hydration to help mitigate dryness.
• Anti-irritant ingredient (Tasmanian Pepperberry extract) may reduce irritation risk for some users.
• Cruelty-free, vegan, gluten-free, alcohol-free, oil-free, and silicone-free.

Cons and limitations to consider

• The product is a high-strength exfoliant, not ideal for very sensitive skin or first-time acid users without a patch test or slower introduction.
• Exfoliation at night means you must commit to sunscreen every day after use, which could be a daily reminder for some.
• Results depend on consistent use and skin tolerance, immediate dramatic changes aren’t guaranteed.

Who it’s for

This serum suits someone looking to improve skin texture and brightness with a chemical exfoliant and who can commit to a nighttime routine plus daily sunscreen. It may appeal to those who want a straightforward acid-based option with added hydration and a touch of anti-irritant support.

Who it isn’t ideal for

If you have highly sensitive skin, a history of irritation with acids, or you’re new to exfoliating formulas, you might prefer a lower-strength option first or to introduce the product gradually.

When it makes sense to buy

• You want a high-strength exfoliant that targets texture and tone in a single step.
• You’re comfortable with a nightly skincare routine and the sunscreen habit that follows.
• You value a cruelty-free, vegan, and generally clean ingredient approach.

What to review before purchasing

• Your current tolerance for AHAs and any known sensitivity to lactic acid.
• Your daily sunscreen habit and how you’d integrate it after nightly use.
• Any skin concerns beyond texture and brightness (e.g., active breakouts, rosacea) that might affect suitability.

Practical usage example

After cleansing, you apply a small amount of the serum to a clean, dry face, avoiding the eye area. If you’re new to acids, you might start 2–3 nights a week and increase as tolerated. In the morning, you continue with a broad-spectrum sunscreen. Over several weeks, you may notice a smoother surface and a more even tone as dead surface cells shed and moisture supports plumpness.

Quick comparison approach

If you’re choosing between this high-strength exfoliant and a gentler option, consider your skin’s current sensitivity, your willingness to maintain a sunscreen routine, and how quickly you want visible texture improvements. For very sensitive or first-time users, a lower percentage or less frequent use could prevent irritation while still delivering benefits over time.
