I understand that acne scarring can be distressing. Atrophic (depressed) acne scars can improve using a combination of subcision and fillers (and fractional lasers as well, although these will not be discussed here to avoid confusion).
Firstly, there are many types of fillers in the market available to fill acne scars, ranging from temporary to semi-permanent fillers, the most commonly used being hyaluronic acid fillers.
Whichever the filler used, the current evidence suggests that scars rarely return to their previous state due to the subcision and the collagen growth and repair on a cellular level, even after all the filler material has been degraded (Aesthetics Journal, Jul 2015).
In addition to hyaluronic acid based fillers, there has been a recent move towards the use of long-chain polynucleotide (PN) products, such as Rejuran, instead. PN products not only “fill” up the space of the acne scars, but also improve the skin’s own tissue and collagen regeneration, hence giving permanent results.
PNs have found to have several biological functions in our skin, such as stimulating wound healing, secretion of collagen proteins and growth of fibroblasts (our body’s own collagen-producing “factories”).
Hope this helps! :)
