This creates transient and aqueous pores on the skin which facilitates the transport of topical drugs and other therapeutic molecules to the epidermis.  For years, microneedling therapy has been a subject of extensive research in terms of intra-dermal and trans-dermal drug delivery.
As of today, microneedles are now being used in the cosmetic industry to disrupt the skin architecture including the deposition and expression of collagen and elastin. It is now being used as a vehicle in delivery cosmetic molecules into the skin in addition to other dermatological treatment like light sources or use of topical agents.

Current studies showed that combining ascorbic acid and retinyl retinoate into microneedling therapy help reduce wrinkles and improve the skin appearance. 
Microneedles are very effective because it provides effective results. It enhances the delivery of the topical agents through enhance penetration in the skin which offers effective delivery of various proteins and peptides.
