What can the product work for?
Anti-aging
What does the product description say?
Smooth Night Serum is a lightweight exfoliating serum which combines gentle acids and moisturisers which work on skin overnight to reduce dullness and appearance of fine lines and wrinkles.
gluconolactone
2.3% -
2.8%
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
lactic acid

2.3%
Irritation risk:
Concentration: Insufficient!
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)
