FAQs

Absolutely. Oily skin can still become dehydrated, especially after cleansing or using acne treatments. This serum provides lightweight hydration without feeling greasy, helping skin stay balanced and comfortable.

It combines 14 types of hyaluronic acid, including ultra-low molecular hyaluronic acid, to deliver hydration across multiple layers of the skin's surface. It also contains mineral-rich seawater and soothing ingredients like madecassoside to help support the skin barrier while keeping skin comfortable.

Yes. Because it's primarily a hydrating serum, it layers well with most active ingredients, including vitamin C, retinol, niacinamide, and exfoliators. Applying it before your moisturizer also helps reduce the dryness sometimes associated with stronger actives.

For best results, apply the serum to slightly damp skin after cleansing or toning. This helps hyaluronic acid bind to available moisture, leaving skin feeling plumper and better hydrated.
