PRODUCT DETAILS

Hello, smoother nights. This nighttime serum offers a gentle entry into retinol for beginners and sensitive skin. It pairs 0.08% microencapsulated retinol with 1% bakuchiol to smooth the appearance of fine lines and refine uneven-looking texture, while supporting a firmer-looking complexion.

Beyond fine lines, it brings visible-pore care and a firmer-looking finish to your evening routine. The gentle, milky serum leaves skin feeling smoother and more hydrated immediately after use.

Ceramide NP, sunflower seed oil and fermented rice extract bring moisturizing and nourishing support. Ceramide NP and sunflower seed oil are also highlighted for soothing, while Ceramide NP adds barrier care. It is a well-rounded supporting cast for a retinol-focused formula.

The unscented, artificial-fragrance-free formula comes in an airless pump that helps maintain the potency of its active ingredients—a small detail that is quietly useful.

Key Ingredients

Three open mauve, apricot and auburn grooves arc across one warm-ivory matte plaster surface beside a tiny coral point.

Retinol

Translucent muted-rose abstract sculpture with flowing ridges, softly lit on a seamless warm peach surface.

Bakuchiol

A defined cosmetic ingredient with emerging formula-specific evidence for smoother-looking fine lines and more even-looking tone—not a retinoid or a pregnancy-safety shortcut.

Overlapping ivory wax-like layers on a warm blush background, representing ceramide barrier lipids.

Ceramides

Barrier-supporting lipids that help reduce moisture loss and ease visible dryness.

An ivory paper-thread rice panicle curves across warm hanji beside one tiny coral tack stitch.

Golden oil droplets rest on a pearlescent curved sculpture beside a translucent botanical-like flourish on a warm ivory backdrop.

Sunflower Seed Oil

A seed-derived emollient with small human hydration and barrier signals; acne, eczema-treatment and universal non-comedogenic claims are not established.
