Product summary
What can the product work for?
Works for
Anti-aging
What does the product description say?
Naturally derived Vitamin A (AKA retinal), retinol alternatives & radiance boosters are enhanced by wrinkle-release peptides that help rapidly improve the look of lines, wrinkles & hyperpigmentation.
retinal
0.15% -
0.3%
Irritation risk:
Concentration: Effectiveness: HIGH
One step removed from the biologically active in skin form of vitamin A. Once converted to the retinoic acid in the skin, retinal is proven to be effective against all signs of aging. It improves skin cell turnover, helps fight blemishes and clogged pores, can regulate excess oil production and even skin tone. Concentrations of 0.05% and 0.1% are shown to be effective. It can, however, be irritating
lactococcus ferment lysate
1.8% -
2.2%
Irritation risk:
Concentration: Effectiveness:
LOW
Consists of remains of dead bacteria cells. Is likely helpful in attracting water to the upper layer of the skin. Might be helpful in reducing inflammation and neutralizing free radicals in skin
lactic acid
0.15% -
0.3%
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)
