Kosas Revealer Concealer — Tone 04 N, Hydrating Medium-Coverage Under-Eye & Face Concealer with Hyaluronic Acid

Kosas Revealer Concealer Tone 04 N is a hydrating, medium-coverage liquid concealer made to brighten under-eyes and conceal imperfections while feeling lightweight on the skin.

This concealer combines makeup coverage with skin-supporting ingredients so you can even tone and camouflage dark circles, blemishes, and redness without a cakey finish. The formula is buildable and designed to sit comfortably under makeup or alone, with hyaluronic acid, squalane, peptides, caffeine, and algae extract to help skin appear smoother and more hydrated over time. Kosas follows clean beauty commitments — the product is vegan and cruelty-free and excludes talc, silicones, mineral oil, fragrance, parabens, sulfates, and phthalates.

How much coverage does this concealer provide for under-eye circles?

Revealer offers medium, buildable coverage that's formulated to camouflage dark circles while keeping a natural finish. It balances opacity and blendability so you can layer without looking heavy.

• Medium initial coverage that builds to fuller coverage with light layers
• Brightening finish that avoids a mask-like effect
• Suitable for both spot correction and larger under-eye areas

What skincare benefits does the formula deliver?

The concealer contains hyaluronic acid for hydration plus squalane and peptides to help skin look smoother and plumper. Caffeine and algae extract add an energizing, antioxidant-rich boost to the under-eye area for a fresher appearance.

• Hyaluronic acid draws moisture in for hydrated under-eye skin
• Squalane and peptides support a silky texture and smoother look
• Caffeine and algae extract help reduce the appearance of puffiness and fatigue

Will it crease or settle into fine lines?

The lightweight, crease-resistant texture is formulated to minimize settling and caking. Blending with a damp sponge or fingertip and applying thin layers helps maintain an even finish that layers well under powder or foundation.

• Lightweight liquid that blends evenly for a smooth surface
• Resists caking and reduces visible texture buildup
• Pairs well with both liquid foundations and setting powders

How do I choose and apply Tone 04 N for the best result?

Tone 04 N is a neutral-medium shade intended for medium skin tones with neutral undertones. Apply in small dots beneath the eye or on spots, then blend outward with a brush, sponge, or fingers for seamless coverage.

• Select a shade that matches your jawline or sits slightly lighter for brightening
• Use thin layers and build only where needed to avoid heaviness
• Set lightly with translucent powder if you need longer wear

Who is this for: Kosas Revealer Concealer Tone 04 N suits anyone seeking a versatile concealer that combines makeup coverage with hydrating skincare benefits. It’s ideal for users who want medium, buildable coverage without heavy makeup feel — especially those looking to brighten under-eyes, cover blemishes, or smooth uneven tone while staying within clean, vegan, and cruelty-free standards.
