Hyaluronic Acid vs Squalane
Two popular actives, side by side — no fluff.
Hyaluronic Acid
aka HA, sodium hyaluronate, hyaluronan
Hyaluronic acid is a naturally occurring molecule that can hold up to 1,000 times its weight in water — a claim that's technically true but slightly misleading in skincare context. It's an excellent humectant that draws moisture to the skin, but works best in humid environments or when sealed with an occlusive.
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.
