Salicylic Acid vs Squalane
Two popular actives, side by side — no fluff.
Salicylic Acid
aka BHA, beta hydroxy acid, 2-hydroxybenzoic acid
Salicylic acid is the only commonly used BHA in skincare, and its oil-solubility is what makes it special. It can penetrate into pores to dissolve the sebum and dead cells that cause blackheads and breakouts — something water-soluble AHAs simply can't do.
Squalane
aka hydrogenated squalene, plant-derived squalane, olive squalane
Squalane is the hydrogenated (stabilized) form of squalene, a lipid naturally produced by your skin. It's one of the most universally tolerated moisturizing oils available — lightweight enough for oily skin, nourishing enough for dry skin, and unlikely to cause breakouts in anyone.
