Retinol effect is also possible without retinol, i.e. vitamin A derivative and its side effects on the skin. In the Revitalising Serum, La Biosthétique relies on the outstanding anti-aging effect of two phyto-retinol active ingredients without irritating the skin or causing photosensitivity. The effect is also convincing in clinical tests. Bakuchiol, obtained from the seeds of the babchi plant, which has been used for thousands of years in the healing arts, activates cell renewal like retinol and thus has an intensive effect against lines and wrinkles. It works in synergy with the specially prepared resin of the Greek mastic tree. This prevents the breakdown of retinol in the skin, improves its density and elasticity and ensures a soft but firm and taut skin structure. In the Revitalising Serum, this ground-breaking anti-ageing technology is concentrated in a fragrance-free, light and ultra-soft texture that melts into the skin immediately after application and targets wrinkles, whether on the face, neck and décolleté or in the sensitive eye area.
