The Booster 27 from Cosmetics 27 works as a renewal activator that stimulates and reboots the skin's natural self-regenerating and self-protection functions while preserving its protective barrier and microbiota integrity. The serum also helps to regenerate collagen production, restructure the hydro-lipidic barrier, and minimise the appearance of dilated pores for a smoother, firmer and more radiant complexion.
