Acne scarring is a debilitating condition which drives us to seek out and spend vast amounts of money in a quest to improve the situation. Scarring is the result of skin damage during the healing of active acne. This process produces two typical scar types: atrophic and hypertrophic scars, depending on whether there is a net gain or loss of collagen in the healing process. A net loss forms an atrophic scar and a net gain a hypertrophic or keloid scar.
Dermal fillers offer an effective solution for scar reduction. However, only atrophic scars can be treated because they are the only scars which are depressed. Results are seen instantly and improve over weeks as there is a double effect from the procedure: physical lifting up and out of the scar, and collagen development that often follows from fibroblast stimulation in the dermis by the needle.
Essentially, any proven safe dermal filler could be used, and selection depends on the experience of the practitioner. Hyaluronic Acid dermal fillers are the most commonly used. Restylane Refyne is great for direct lifting out of scars because it is firm enough to lift out deep scars but malleable enough to mould if necessary. Restylane Vital and Vital Light are good for an all over skin improvement and is extra beneficial when treating skin in poor condition with additional acne scarring, rehydrating rather than volumizing to improve overall skin texture. As these two fillers are resorbable fillers, the effects are not permanent, although longevity varies. As well as HA, potential compatible filler types include poly-l-lactic acid such as Sculptra, polymethylmethacrylate such as Aquamid and calcium hydroxylapatite such as Radiesse.
