Does 1 Hour Ala -pdt with Omnulix 415 Led Effect Collagen?

i know blue 415nm penetrates shallow versus red 633nm... but i read blue LED versus red with ALA has less side effects such has post inflammatory hyperpigmentation, blisters etc. would ala-pdt 1 hr activated by blue LED even though, blue light doesnt effect collagen on its own, stimulate collagen production?
