USOLAB Bio Tone Up Whitening Face Mask 50 ml

A brightening treatment mask that lifts dullness and evens skin tone, with a visible result from the first use and a gradual effect on pigmentation with continued use.

Niacinamide 2% and tranexamic acid work on pigmentation of any origin, freckles and the marks left behind by breakouts, while helping prevent new discolouration from forming. Lemon fruit water forms the base of the formula in place of water, and glycerin and shea butter maintain hydration throughout.

Light cream texture with a citrus scent. Rinses off without leaving the skin tight.

Best for

Dull, pigmented skin that has lost radiance. Post-acne marks and uneven tone. Early signs of ageing, loss of firmness and elasticity. Skin showing the effects of sun exposure and oxidative stress.

Key ingredients

• Niacinamide 2% — evens skin tone, works on existing pigmentation and helps prevent new marks forming, reinforces the hydrolipid barrier and reduces water loss, softens the look of fine lines
• Tranexamic acid 0.5% — reduces discolouration and the visibility of post-acne marks without irritation and without increasing sun sensitivity, and strengthens the barrier in reactive, easily reddened skin
• Lemon fruit water 52% — replaces water as the base of the formula, contributing vitamin C and natural acids that refresh the complexion, refine the look of pores and restore the skin's natural pH
• Glycerin 10% — draws moisture into the skin and holds it there, so brightening never leaves the skin dry
• Shea butter — restores the lipid barrier and leaves the skin soft
• Arbutin and glutathione — antioxidant support for a clearer, more even complexion
• Goat milk extract and milk protein — nourish and soften, ease puffiness and tightness, leave the skin velvety
• Centella asiatica — calms redness and irritation, supports skin recovery

Formulated without sulfates, parabens, alcohol or mineral oil.
