Anti-aging
What does the product description say?
Derived from beet sugar in France, this vegan, bio-based lactic acid delivers smoother, brighter, younger-looking skin by stimulating skin exfoliation and cell renewal while keeping skin moisturised and firm.
lactic acid
4.4% -
6.6%
Irritation risk:
Concentration: Effectiveness:
MEDIUM
An exfoliating and moisturizing alpha-hydroxy acid (AHA). Typically causes less irritation than other AHAs, for example, glycolic acid. At high concentrations (about 15%), lactic acid can help reduce lines and wrinkles. Recent studies show that lactic acid can support the "good" bacteria living on skin's surface (healthy skin microbiome)
algae extract
0.5% -
1.15%
Irritation risk: Comedogenicity: High
Concentration: Effectiveness:
LOW
Plant extract that helps the skin to attract water and make it more smooth for touch. Also shows promise of anti-aging properties, but research is not extensive yet
gluconolactone
0.45% -
1.05%
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
Evens skin tone
What does the product description say?
Poly-hydroxy acid (PHA) improves texture and uneven skin tone, reduces the size of pores and raises the skin's moisture levels.
