brightening, antioxidant-rich serum designed to fade dark spots, even skin tone, and boost radiance. Key actives include:

Glutathione — powerful antioxidant that helps inhibit melanin production
Vitamin C (in stable forms, plus derivatives) — for oxidant protection, brightening & tone evening
Niacinamide (≈ 5%) — to brighten, improve barrier function, reduce uneven tone & support skin health
Tranexamic Acid (≈ 4%) — to target stubborn discoloration & hyperpigmentation;

It also contains soothing, hydrating, and barrier-supporting ingredients (panthenol, ceramide NP, beta-glucan, etc.) to help mitigate irritation from the actives.

After cleansing and toning, apply 3-5 drops of the serum to face (and neck if desired). 

Use it AM or PM, but especially AM because of the antioxidant benefits. If using in the morning, always follow with sunscreen.

Introduce gradually if you have sensitive skin (every other day → daily). Always patch test.
