Comfortable Feel – Each formula offers high color pigmentation and long wear while feeling light and breathable on the skin.
Inclusive and Expressive Beauty – Kosas embraces diversity and individuality, offering an inclusive color palette with universally flattering shades.
Scientifically Sound Innovation – The brand combines skincare and makeup science to ensure that every product not only enhances appearance but also promotes skin health.

The Revealer Concealer is Kosas’ best-selling product—a creamy, hydrating concealer that doubles as a skincare product. Enriched with caffeine, peptides, and hyaluronic acid, it brightens the under-eye area, conceals blemishes, and moisturizes without settling into fine lines. Its natural finish makes it perfect for both subtle and full-coverage looks, leaving a radiant, natural glow.
The Wet Lip Oil Gloss combines the shine of a lip gloss with the care of a lip balm. Enriched with hyaluronic acid, peptides, and avocado oil, it smooths and plumps the lips, giving them a delicate, glossy sheen. It’s non-sticky, provides intense hydration, and is a must-have for anyone who wants nourished, easy-care lips.
The Cloud Set Powder is a weightless, silky powder that sets makeup without compromising your natural glow. It uses pure, oil-absorbing ingredients to reduce shine and maintain a flawless finish. The finely milled texture minimizes pores and smooths the skin for a soft-focus effect – ideal for everyday use or on-the-go touch-ups.
