PRODUCT DETAILS

Hello, glow. This capsule-in-serum formula places visible astaxanthin capsules within a facial serum. The capsules are formulated to support more even-looking tone and visible glow, giving the product its distinctive look and purpose.

Niacinamide, glutathione and tranexamic acid add to the tone-focused blend. Together, they support the appearance of a more even complexion without turning your routine into a complicated project.

Hydration has its place here too. Hyaluronic acid, beta-glucan and ceramide derivatives help provide hydration and moisture retention. The serum leaves skin feeling soft without heaviness, balancing its tone-focused ingredients with everyday moisture support.

The transparent texture has a lightweight, non-greasy feel that layers easily under other skincare. It absorbs easily and is intended for normal, combination and sensitive skin, making it a considered choice when you want tone and hydration support in one lightweight, easy-to-layer serum.
