Kosas Revealer Concealer, Medium Coverage Hydrating Under‑Eye & Spot Concealer — Tone 01 N, Hyaluronic Acid

Kosas Revealer Concealer in Tone 01 N is a hydrating, medium-buildable liquid concealer designed to brighten under-eyes and conceal spots while delivering skincare benefits like hyaluronic acid and peptides.

This lightweight concealer pairs makeup coverage with nourishing ingredients so you can blur dark circles, even tone, and maintain a natural finish without heavy, cakey buildup. The formula layers easily under foundation or wears alone, and it’s formulated to be vegan and cruelty-free, free from talc, silicones, mineral oil, fragrance, parabens, sulfates and phthalates.

How does this concealer perform on under-eye darkness and fine lines?

Revealer is formulated for under-eye use with a hydrating base to help minimize the look of creasing while providing medium, buildable coverage. It aims to brighten and conceal without settling into fine lines thanks to humectants and smoothing emollients.

• Hydrating hyaluronic acid reduces dryness that accentuates lines.
• Blendable, lightweight texture resists caking and creasing.
• Medium coverage conceals darkness while allowing natural skin texture to show through.

Can I use this concealer for spot coverage and overall brightening?

Yes—the Revealer formula is designed for multi-use, functioning equally well as a precision spot concealer and an under-eye brightener. It layers smoothly over foundation or on bare skin for targeted coverage with a natural finish.

• Buildable formula treats blemishes and discoloration without looking heavy.
• Applies easily with brush, sponge, or fingertips for precise placement.
• Resists settling into pores and maintains even tone across the face.

What skincare ingredients are included and what do they do?

Beyond pigment, the formula includes a blend of hydrators and skin-supporting extracts to help maintain a smooth appearance while you wear makeup. These actives are chosen to hydrate, soothe, and support visible skin texture.

• Hyaluronic acid: draws and retains moisture for smoother-looking skin.
• Caffeine and peptides: help soothe and energize the under-eye area’s appearance.
• Squalane and algae extract: lightweight emollients that help maintain softness and balance.

How long does it last and what’s the finish like throughout the day?

The concealer is formulated to be lightweight and crease-resistant, keeping coverage intact for routine daily wear. Finish is natural to slightly luminous, making it suitable for both everyday and photo-ready looks.

• Natural finish that doesn’t look flat or powdery on skin.
• Stays put under foundation and resists obvious fading or flaking.
• Works with setting powder when longer wear is needed.

Who is this for: Kosas Revealer Concealer in Tone 01 N is made for anyone looking for a reliable, skincare-forward concealer that balances visible coverage with hydrating comfort. It’s especially suited to people who want medium, buildable coverage for under-eye brightening and spot correction without the heaviness of traditional concealers, and those who prefer clean, cruelty-free beauty formulas.
