PDT may boost collagen production
Photodynamic therapy has many effects on a molecular level--it preferentially targets precanceous lesions (in the treatment of actinic keratoses) and can help to shrink oil glands (improving acne and enlarged oil glands called sebaceous hyperplasia). Collagen production can be augmented, and this effect may be further improved depending on the light source used. Using an IPL or pulsed dye laser in addition to blue light may further boost collagen production. Both of these...

Its major effect on the skin is the photochemical reaction where precancerous lesions get preferentially inflamed and sloughed off. Collagen stimulation is a nice bonus, as confirmed by molecular markers as published in the study. However, one may see equal if not greater collagen stimulation over a period of time from...
