We double-checked with Clarins for you, and here is their response:
Double Serum is an exceptional serum suitable for all skin type as it immediately introduce active ingredients to the skin which stimulate the 5 vital functions of the skin, namely hydration, nutrition, oxygenation, protection and regeneration. A large portion of the active plant extracts are organic which definitely have a better affinity with the skin in terms of absorption. The actions of all these plant extracts will certainly benefit a skin after the micro-needling and will most likely even assist with the repair and comfort of the skin
During the treatment of micro-needling, the needle only penetrates through the epidermis and does not remove it therefor the skin’s natural protective barrier remains intact. The pierced epidermis rapidly heals in a matter of hours. After the procedure, the treated skin has the appearance of moderate sunburn which improves over the next 24 to 48 hours.
