What It Does

A lightweight, stable oil that mimics the skin's natural sebum. Absorbs quickly without greasiness and suits all skin types.

Squalane is a stable, saturated form of squalene, an oil naturally produced by human sebaceous glands. Our skin produces squalene to keep itself moisturized, but production peaks in our teens and declines steadily with age. Topically applied squalane replenishes this lipid, providing lightweight hydration without greasiness.

Squalane can be derived from shark liver (traditional source), olives, or sugarcane. Most modern skincare uses plant-derived squalane for sustainability and ethical reasons. It is prized for its ability to mimic skin natural oils, making it exceptionally compatible with all skin types. It absorbs quickly, does not clog pores, and provides a smooth, non-greasy finish.

Japanese brands like HABA have built their reputations on high-purity squalane. HABA Squalane Oil is a cult favorite in Japan, known for its minimal ingredient list and versatility. It can be used alone as a facial oil, mixed into moisturizers, or applied to hair and nails.

How It Works

Mimics skin natural oils, providing emollient hydration. Forms a lightweight, breathable barrier that prevents moisture loss without clogging pores.

HABA Squalane Oil is a Japanese cult classic known for purity and versatility. Widely used in Japanese skincare as a lightweight moisturizing oil.
