Dermophisiologique’s XTRA TONE Collection has been formulated exclusively to prevent the loss of skin tone and to build skin density as one ages, leaving the skin firmer and more supple. Dermo-pH’s products within the XTRA TONE Collection boost and renew the structures supporting the skin while enabling structural proteins – such as collagen and elastin – to more efficiently synthesize. Innovative technology such as: Matrikines (messenger peptides), ATiPenergy® phytocomplex, Iso-Aminoacids and Ceramide 2 help to improve cell exchange, stimulate cell metabolism and assist the epidermis in combatting poor elasticity.
