Why Do Augmentation Scars Need Sunscreen?
UV triggers excess pigment in immature scar tissue, turning a fading line brown — protection during the first year keeps it on track.
A maturing scar is biologically different from the skin around it: its pigment cells are unstable and overreact to UV. The same sun exposure that gives normal skin an even tan can set a scar at a darker colour that no longer fades with the season.
One year of shade shapes decades of scar
Standard advice runs six to twelve months of protection while the scar matures: high-SPF broad-spectrum sunscreen once the incision has fully closed, clothing or silicone tape before that. Inframammary scars hide under most clothing, but swimwear, low necklines and beach days expose them more than people expect. Scar biology varies between individuals, so some need longer.
Reapply on beach days and after swimming, and treat a scar that is turning darker or raised as a prompt to act early. A quick consultation can sort ordinary pigmentation from a scar that would respond better to active treatment.
