Product summary
What can the product work for?
Evens skin tone
What does the product description say?
4% Gluconolactone (PHA) Gently, yet effectively, exfoliates dull skin buildup to uncover healthier-looking skin and to reveal a more even skin tone and texture.
gluconolactone
3.9% -
5.8%
Irritation risk:
Concentration: Effectiveness: HIGH
A polyhydroxy acid (PHA) that helps shed the dead cells from the skin surface revealing smoother skin. Is believed to be genter than AHAs. It helps attract water to the upper layer of the skin and can stimulate production of skin's own hyaluronic acid resulting in improved hydration levels. It has been shown to be helpful against acne and clogged pores if used consistently (e.g over a period of 12 weeks) in high enough concentration. It can help reduce fine lines and wrinkles and improve skin tone with long-term application. Can help neutralize free radicals
lactobionic acid
1.6% -
2.4%
Irritation risk:
Concentration: Effectiveness: HIGH
A polyhydroxy acid (PHA) that helps shed dead cells from the surface of the skin revealing a smoother, more even skin. PHAs tend to be gentler on the skin compared to AHAs (for example, glycolic acid). It also has hydrating properties and helps attract water to the upper layer of the skin. It can help calm down inflammation in skin and support restoration of the barrier function. It has an anti-oxidant effect as well. It can help reduce fine line, wrinkles and improve skin elasticity
camellia sinensis leaf extract
0.95% -
1.45%
Irritation risk:
Concentration: Effectiveness:
LOW
Can contain potent anti-oxidant compounds (abbreviated ECG, GCG, EGC, and EGCG) that might help protect the skin from free radicals. Can help calm down inflammation and has some anti-bacterial properties. Unfortunately, these antioxidants are unstable and lose their effectiveness very quickly in products. The concentration of the antioxidant compounds in the extract also tends to be low to be effective in topical formulation
