Lactic Acid

Lactic acid is a gentle yet effective AHA (alpha hydroxy acid) that exfoliates, hydrates, and brightens skin, making it ideal for dry, sensitive, and aging skin. Compared to glycolic vs. lactic acid, lactic acid offers a milder exfoliation while boosting moisture retention. A lactic acid serum smooths texture and enhances radiance, while a moisturizer with lactic acid refines skin without stripping hydration. It also pairs well with retinol, improving cell turnover while reducing irritation. At Dermacart, we offer medical-grade lactic acid skincare in Canada, trusted by dermatologists for visibly smoother, more radiant skin.

We’ve answered your common questions about Lactic Acid.

How is lactic acid produced?

Lactic acid is a naturally occurring AHA (alpha hydroxy acid) derived from fermented milk, fruits, or plant-based sources. In skincare, it is synthetically produced to ensure purity and effectiveness. It works as a gentle exfoliant that helps remove dead skin cells while hydrating the skin.

Can lactic acid be used with retinol?

Yes, lactic acid and retinol can be used together, but with caution. Since both promote skin renewal, using them on the same night may cause irritation. To avoid sensitivity, alternate their use on different nights or apply lactic acid first, followed by retinol after your skin adjusts. Always follow with a moisturizer.

Which lactic acid is best?

The best lactic acid products contain a balanced concentration (5-10% for daily use, up to 15% for stronger exfoliation) and include hydrating ingredients like hyaluronic acid to prevent dryness. Medical-grade lactic acid serums and moisturizers, available at Dermacart, are clinically formulated for safe and effective exfoliation.

What does lactic acid do in skincare?

Lactic acid exfoliates dead skin cells, improves skin texture and radiance, boosts hydration, and helps fade dark spots and fine lines. Unlike stronger AHAs, it gently resurfaces the skin while retaining moisture, making it ideal for sensitive and dry skin types.

Will lactic acid lighten skin?

Lactic acid does not bleach or lighten skin, but it helps fade hyperpigmentation, dark spots, and uneven skin tone by accelerating cell turnover. Regular use can lead to a brighter, more even complexion without altering your natural skin tone.

Discover the best medical-grade lactic acid serums and moisturizers in Canada, formulated to gently exfoliate, deeply hydrate, and enhance skin radiance without irritation. Lactic acid, a gentle AHA (alpha hydroxy acid), works to dissolve dead skin cells, revealing a smoother, more youthful complexion while boosting moisture retention for lasting hydration.

Is your routine all set?

A full skincare routine is essential because your skin needs more than basic cleansing and hydration to stay healthy. Cleansers remove dirt, but serums target specific issues like aging or dark spots, while moisturizers lock in hydration and sunscreen protects from damage. Investing in the full routine ensures long-term skin health and visible results.
