USOLAB Bio Brightening Ampoule

A brightening ampoule for a more even, radiant skin tone. With arbutin 2 % to visibly fade the look of dark spots, freckles and post-blemish marks.

Tranexamic acid 2 % — helps even the tone and fade the look of marks left after blemishes.

Glutathione 5 % — an antioxidant that supports radiance and helps skin look fresh and renewed.

Lemon extract — the base of the formula. Brightens, helps refine the look of pores and evens the tone.

17 amino acids — support the skin's natural moisture and help defend it against free radicals.

30 peptides — help soften the look of fine lines and refine texture.

Who it suits. Any skin with uneven tone or dullness, from around thirty.

How to use. A few drops on cleansed skin after toner, morning or evening. Follow with your cream. Use SPF during the day.

Key ingredients and benefits:

Arbutin 2 %
Works on pigmentation of any origin, and above all on preventing it: it blocks the enzyme that starts melanin production, so new spots and freckles are far slower to appear, while the ones already there fade with regular use. It also evens out texture and tone, has an antiseptic action, removes toxins, reduces puffiness and brings back elasticity and softness.

Glutathione 5 %
Accelerates the regeneration of damaged tissue and slows its ageing. Improves elasticity, takes part in the formation of collagen and elastin, clears pigment spots and improves the condition of the skin after invasive procedures.

Niacinamide 2 %
Blocks the transfer of pigment into the surface cells. It strengthens the hydrolipid barrier, prevents dehydration, calms inflammation, softens fine lines and protects against oxidative stress.

Tranexamic Acid 2 %
Suppresses the formation of pigment itself, so marks fade and new ones are prevented. Together with niacinamide the two work better than either does alone.

Idebenone
An antioxidant ten times more effective than coenzyme Q10. It works in the deeper layers, pushing wrinkles out from within and keeping collagen and elastin fibres from breaking down.

Lemon Extract
The base of the formula. Exfoliates gently, brightens and gives the skin its glow.

17 Amino Acids
Block melanin production and prevent free radical formation. They stimulate collagen synthesis, improve texture, support renewal and regeneration and raise the skin's Natural Moisturising Factor.

30 Peptides
Work on elasticity and firmness, give the skin volume and even out its relief. They visibly reduce wrinkles and prevent new ones from forming.

Apply a few drops of the serum onto cleansed skin after toner, massaging it in gently. Follow with your regular cream.
