Retinol + Lactic Acid (AHA)

Can you use Retinol with Lactic Acid?

Yes, with timing

Yes, with timing. Use Retinol and Lactic Acid on alternating nights rather than together.

Why

Lactic acid is a gentler AHA than glycolic acid, but it still exfoliates, and retinol also increases turnover. Layered on the same night they can cause dryness and peeling. Alternating nights gives you smoother texture from both with less irritation.

How to use them together

  1. Night A: Retinol. Night B: Lactic Acid. Or use Lactic Acid in the morning and Retinol at night if your skin tolerates it.
  2. Start slowly (2-3 nights a week each) and moisturize.
  3. Daily sunscreen is essential with both.

Who should be careful

Beginners, people with sensitive skin, rosacea or eczema, and anyone using prescription retinoids should ask their dermatologist before combining.

About the ingredients

Retinol: An over-the-counter vitamin A derivative (retinoid) used for fine lines, texture and uneven tone. It converts to retinoic acid in the skin, so it is milder and slower than prescription tretinoin.

Lactic Acid (AHA): A gentler alpha hydroxy acid with a larger molecule than glycolic acid. Exfoliates and helps hydrate. Like all AHAs, it can increase sun sensitivity.
