Lactic Acid 10% + HA

The Ordinary Lactic Acid 10% + HA is a high-strength overnight exfoliating serum. Lactic acid — an alpha hydroxy acid — sweeps away dull surface cells while Tasmanian pepperberry works to keep the visible sensitivity that usually comes with exfoliation in check.

What it actually does

• Exfoliates chemically. Lactic acid is an AHA that lifts off dead surface skin — the route to the smoother, healthier-looking skin the brand promises from this peeling formula.
• Buffers the process. Tasmanian pepperberry is included to reduce the visible signs of inflammation and sensitivity that often accompany exfoliation, according to The Ordinary.
• Aims at texture, dullness and fine lines — the three concerns this serum is formulated around.
• Clean formula profile: made without oil, alcohol, silicone, nuts, gluten or fragrance, and free of parabens, sulfates and phthalates. Vegan, gluten-free and cruelty-free.

How to use

1. Apply once per day, ideally in the evening.
2. Building tolerance? Dilute it with your other treatments at first, then work up to the full strength.
3. Keep it away from the eyes, and never use it on sensitive, peeling or compromised skin.
4. AHAs can raise your skin's sun sensitivity — wear sunscreen daily and limit sun exposure while you use it.

Questions

Is 10% too strong to start with?

If you're new to acids, you can blend each dose with other treatments to lower the strength until your skin adjusts — the brand itself suggests this approach.

Do I really need sunscreen with it?

Yes. This serum contains an AHA that can make skin more sensitive to the sun — daily sunscreen, protective clothing and limited sun exposure are part of using it responsibly.

When should I apply it?

Once a day, and evening is the recommended slot.
