Multi-Acid Drip AHA/PHA Resurfacing Serum
gluconolactone
4.7% -
5.7%
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
glycolic acid
2.3% -
2.8%
Irritation risk:
Concentration: Effectiveness: HIGH
An alpha-hydroxy acid (AHA) that helps to remove the dead skin cells on the surface of the skin reveling a more even, smoother complexation. It is also able to stimulate collagen production with long-term use. Could help to reduce pore congestion. It can be irritating to the skin. Apply sunscreen daily if using products with glycolic acid
salix alba bark extract
1% -
1.2%
Irritation risk:
Concentration: Effectiveness:
LOW
A plant extract that can help neutralize free radicals in skin. It contains a compound salicin that can theoretically be converted into salicylic acid that, in turn, helps reduce inflammation in skin, but the evidence of effectiveness in skin is lacking and the extract is usually not used in a concentration that would enable an exfoliating effect

Concentration: Insufficient!
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
