I have seen this qu posted several times before and I have now experienced it myself, having notice accelerated aging on the back of my wrists on the fold, arms, legs etc. The skin is not as resilient and soft as it was and I am certain the laser is the cause. In 10-15 years time I expect they will realise this and look for a different technology. I have always had very young skin, soft and smooth. I never go in the sun and I protect it well. The laser is the only explanation.
