Reduced shine and fewer breakouts - with 10% Niacinamide

Niacinamide, a form of vitamin B3, helps regulate excess oil and addresses redness at a 10 percent concentration. The serum’s thin consistency supports absorption so the active ingredient reaches the surface layers effectively.

Visible shine reduction and fewer spot flare-ups when used consistently, particularly useful for oily or congested skin.

Hydration without heaviness - with 1% Hyaluronic Acid

Hyaluronic Acid at 1 percent provides lightweight hydration and aids delivery of actives by maintaining moisture at the skin surface. The formulation balances hydration while avoiding a greasy finish.

Skin feels plumped and comfortable under moisturiser and makeup, without increasing surface oiliness.

Simple routine integration - with a fragrance-free, lightweight formula

Thin, layerable texture and a fragrance-free formulation make it suitable for AM and PM use and for pairing with other serums in any order. Instructions recommend a pea-sized amount patted into face and neck after cleansing.

Adds easily to existing routines, offering targeted oil control without disrupting other skincare steps.
