What is Lactic Acid?
Lactic acid as used in skincare, is an AHA made from fermented milk, or synthetically for use in cosmetics. It works by loosening the grip between dead skin cells, so they can be sloughed off more easily.
What sets lactic acid for skin apart from other AHAs such as glycolic acid is that its molecular size is larger, which makes it penetrate less deeply — and that’s a good thing. It sloughs off the top layer without irritating it, a blessing especially for sensitive complexions.
Plus, it’s a humectant. Which is to say it pulls water to it, leaving you with not just a scrub but a treatment: Water that’s brought to it upon contact provides hydration as it’s being exfoliated. That’s one of the standout strengths of lactic acid — you’re not just removing some old skin, you’re helping the new one below it thrive.
Forms of Lactic Acid in Skincare
When it comes to skincare, you’ll encounter lactic acid in a variety of product types. Here’s how it’s commonly used:
- Cleansers: Gentle daily exfoliation, perfect for those new to the routine.
- Toners: Provides gentle exfoliation with added hydration.
- Serums: More potent; excellent for focused therapy.
- Peels: High potency formulas that can be used once or twice weekly.
- Body Lotion: Use for body exfoliation or overnight treatments.
Key Benefits for Your Skin
The upside of lactic acid is more than just a surface-level exfoliation. Here’s why it deserves a place in your skincare roster:
- Gentle Yet Effective Exfoliation: Sloughs away rough, dead skin without scrubbing.
- Boosts Radiance: Regular use of lactic acid for skin will reveal smoother, brighter skin.
- Improves Texture: Rough patches? Bumps? It helps even everything out.
- Hydrates Skin: Unlike other exfoliants, it seals moisture in while sloughing away the old cells.
- Reduces Hyperpigmentation: Adios, dark spots, sun damage and uneven tone.
- Softens Fine Lines: Consistent use helps smooth out lines and wrinkles.
- Enhances Product Absorption: It helps serums and moisturizers penetrate better by exfoliating the dead skin layer.
How to Incorporate It into Your Routine
If you’re curious how to use lactic acid, here’s a step-by-step breakdown:
- Ease into It: For new users, 2–3 times a week at night is perfect.
- Cleanse for Best Results: Apply to clean, dry skin every time.
- Apply Serum or Toner: Pick a percentage that fits your ski type (5% to 10%).
- Moisturize After: Finish your routine with a soothing, hydrating moisturizer.
- A Necessity For All Skin Types: Daily use of sunscreen is recommended as AHAs may increase skin sensitivity to the sun.
My Pro Tip: Want to get the most out of lactic acid? Pair it with hyaluronic acid to hydrate and calm the skin after exfoliation.
Best Ingredients to Pair
Lactic acid combined with other acids or ingredients may function even better. Here is a table of the best combinations:

What to Avoid Mixing With
Although lactic acid skin benefits are multi-faceted, you’ll want to avoid mixing this powerful ingredient with any of the following to prevent skin sensitivity:
- Retinol: They’re both exfoliants; using them in conjunction can be irritating.
- Benzoyl Peroxide: It can cancel out lactic acid.
- Other Powerful Acids: Over-exfoliation if used with AHA or BHA.
My Quick Tip: If you really need to use these ingredients, alternate day to avoid irritation.
