What is Salicylic Acid?

Salicylic acid, a type of beta hydroxy acid (BHA), comes from willow bark.Unlike alpha hydroxy acids (AHAs), which are water-soluble, it is oil-soluble—meaning it can go deep into your pores and dissolve excess sebum, debris, and dead skin cells.

A Brief History of Salicylic Acid in Skincare

The use of it dates back to ancient times when willow bark was used for its anti-inflammatory properties. Fast forward to modern science, and It is now FDA-approved for treating acne and skin conditions like psoriasis and seborrheic dermatitis.

How Salicylic Acid Works on Skin

The Science Behind It

It exfoliates your skin from the inside out. It essentially loosens the bonds that hold dead skin cells together, allowing them to shed away and uncover the fresher skin beneath.

Oil-Soluble Exfoliation Explained

Unlike AHAs, salicylic acid can cut through oil and penetrate deeply into pores, making it ideal for treating blackheads, whiteheads, and clogged pores.

Penetration Into Pores

Because it’s oil-soluble, it travels deeper into the skin than other exfoliants, tackling the problem at the root—literally. It’s like sending a microscopic plumber into your pores.
