Acne & Scars
Acne leaves two types of damage: active lesions and the marks they leave behind. Both have different mechanisms. Treating them the same way is the first mistake.
Post-inflammatory melanin, the brown mark left after a spot, forms in the dermis at a depth of 1.5 mm. Vitamin C or retinol serums reach 0.2 mm. It's simple maths: they cannot solve a problem they cannot reach.
Atrophic scars (hollows) are a loss of tissue. The only way to fill them is to stimulate the production of new collagen from within. LaseMD Lutronic does this through fractional micro-ablation. Genius RF does it through radiofrequency. These are not "improved" treatments: they are treatments that work at the right depth.
It's not your skin that is difficult. It's the method that didn't go deep enough.
