Exfoliating Acids 101

Lactic vs. Glycolic vs. Salicylic

If you’ve ever looked at a skincare label and seen words like “AHA” or “BHA” and thought, What does that even mean?—this guide is for you. We’re breaking down the three most popular exfoliating acids: lactic, glycolic, and salicylic—what they do, who they’re for, and how to use them.

First: What Are Exfoliating Acids?

Unlike scrubs, which use physical particles to remove dead skin, acids do the job chemically—gently loosening the bonds between dead skin cells so they can shed naturally. This smooths texture, evens tone, and boosts skin renewal. The right acid can treat anything from dullness to acne to fine lines.

1. Lactic Acid (AHA) – Gentle, Hydrating, Brightening

Best for: Dry, sensitive, or textured skin
Think: Glowy, hydrated, smoother skin

Lactic acid is an AHA (alpha hydroxy acid) that works on the skin’s surface. It exfoliates while pulling in moisture, so it’s ideal if you want brighter skin without irritation. It’s also amazing for smoothing rough patches and treating keratosis pilaris (“chicken skin”).

Try it if you want to:

Fade dark spots
Hydrate and exfoliate in one step
Improve texture without drying out

Recommended Products:

12% Lactic Acid Exfoliant – Effective yet gentle enough for regular use.
Chocolate Face Mask with Lactic Acid – A soothing, nourishing mask that exfoliates and hydrates with the added indulgence of cocoa.

2. Glycolic Acid (AHA) – Powerful, Resurfacing, Radiance-Boosting

Best for: Normal to oily skin, early signs of aging
Think: Deep exfoliation, glow-up results

Glycolic acid is also an AHA but has a smaller molecule than lactic acid, meaning it penetrates deeper. It’s great for tackling fine lines, dullness, and uneven skin tone—but it’s stronger, so you’ll want to ease in.

Try it if you want to:

Treat pigmentation or sun damage
Smooth fine lines
Get that fresh, “glass skin” look

Recommended Products:

10% Glycolic Acid Toner – Balanced with aloe and hyaluronic acid
30% Glycolic Acid Peel – High strength, ideal for experienced users

3. Salicylic Acid (BHA) – Pore-Clearing, Oil-Busting, Acne-Fighting

Best for: Oily, acne-prone, or combination skin
Think: Clearer skin, fewer breakouts, tighter pores

Salicylic acid is a BHA (beta hydroxy acid) that goes deep into pores to dissolve oil and dead skin. It’s a go-to for acne, blackheads, and shiny T-zones. Unlike AHAs, it’s oil-soluble, which makes it effective inside the pores.

Try it if you want to:

Prevent or treat breakouts
Minimize clogged pores and blackheads
Balance oily skin without over-drying

Recommended Product: Salicylic Acid Toner 2% – Lightweight and refreshing with aloe, witch hazel, and peppermint.

Pro Tips for Using Acids:

Start slow. Once or twice a week, then increase as your skin adjusts.
Don’t mix them. Avoid layering acids or combining with physical scrubs—this can irritate your skin.
Use sunscreen. Acids make your skin more sensitive to the sun. Always protect your glow.
