Anytime the skin is over dried, existing lines and wrinkles will become more apparent, particularly fine lines. Mostly everyone will acclimate if BPO is used correctly and consistently (slow intro, slow increase in % like we do) and any dryness/irritation will subside. However, skin that is dry/dehydrated does give the illusion of aged skin as it can look creepy as if lots of instant fine lines appeared overnight. This dehydrated skin condition is only temporary and does not affect the skin’s collagen and elastin or age the skin in any way.  As you know we do not use moisturizer at night but you can use it during the day between regimens. We can also pull in anti aging products once you are clear if this is something you want to take preventative measures for moving forwards.
