Product summary
What can the product work for?
Evens skin tone
What does the product description say?
Additional ingredients include PHA to gently exfoliate and smooth skin without irritation, and niacinamide to brighten skin and reduce the appearance of dark spots.
niacinamide
3.4% -
5.2%
Irritation risk:
Concentration: Effectiveness: HIGH
Is proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles. It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture.
The concentration of about 2% is effective for supporting the skin barrier and evening out the skin tone. Concentration of 4-6% is better for helping with acne and balancing the sebum production
madecassoside
0.35% -
0.85%
Irritation risk:
Concentration: Effectiveness:
LOW
An antioxidant that is typically derived from plant Centella Asiatica. It can help neutralize free radicals in skin and support skin barrier function. It could, however, itself be irritating. It is often unstable in formulations
gluconolactone
0.9% -
1.4%
Irritation risk:
Concentration: Insufficient!
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
