lash oil

Many lash products are oil‑based—castor oil is a common primary ingredient. Serums often include active ingredients such as biotin, peptides and niacinamide. Formulations also blend castor with botanical oils (for example, moringa or amla) and may add vitamin E for conditioning.

Apply to clean lashes or brows, usually at night, using the product’s applicator or a spoolie. Many listings recommend leaving the product on overnight and washing in the morning to reduce irritation. Typical frequency is once nightly unless the product label says otherwise.

Age recommendations vary: some listings state “All Ages” or “Adult,” while others specify minimum ages such as 13+ or 18+.

Castor‑based oils are also marketed for hair and scalp support, skin moisturization, eyebrow conditioning, massage blends and general hydration or DIY beauty treatments.

Both unscented and scented options appear in the category: some products are explicitly labeled “unscented,” while others note a fragrance.
