Exfoliation is the secret to glowing, youthful-looking skin. But not all exfoliants are created equal — and choosing the right one for your skin can make all the difference. Two of the most effective, and often misunderstood, exfoliating acids are lactic acid and salicylic acid. Both deliver impressive results, but they work in different ways.
Here’s what you need to know to decide which is best for you.
What is Lactic Acid?
Lactic acid is an alpha hydroxy acid (AHA) derived from milk or plant sources. It works by gently dissolving the bonds between dead skin cells on the surface, revealing brighter, smoother skin underneath.
Benefits of Lactic Acid:
-
Hydrates while exfoliating (unlike harsher acids).
-
Improves texture and radiance.
-
Reduces the look of fine lines.
-
Ideal for dry, sensitive, or mature skin.
👉 Velettà Youthful Glow AHA Radiance Treatment contains 4% lactic acid, making it gentle enough for regular use while still delivering visible results. Our lactic acid is plant based and therefore vegan.
What is Salicylic Acid?
Salicylic acid is a beta hydroxy acid (BHA). Unlike AHAs, it is oil-soluble, which means it can penetrate deeper into pores to clear out sebum and debris.
Benefits of Salicylic Acid:
-
Unclogs pores and reduces breakouts.
-
Calms redness and inflammation.
-
Refines skin texture and reduces shine.
-
Best for oily, combination, or acne-prone skin.
👉 Velettà’s Youthful Glow AHA Radiance Treatment also includes a small amount of salicylic acid (0.25%), offering a clarifying boost without irritating the skin.
Which Should You Choose?
-
If your skin feels dry, dull, or sensitive: Lactic acid is your best friend.
-
If your skin is oily, congested, or breakout-prone: Salicylic acid will work harder for you.
-
If you’re over 35: A combination of both is often ideal — gentle resurfacing from lactic acid plus pore-clearing action from salicylic acid.
Takeaway: You don’t always have to choose one or the other. Products that combine lactic and salicylic acid, like Velettà’s Youthful Glow AHA Radiance Treatment, deliver balanced results for smoother, brighter, and clearer skin.
