I have a client who has extremely thin skin due to years roaccutane and hormone use for acne skin. Even after being as careful as I could she has a patch of red skin by her lip, warm peron rigot wax used. Has anyone got any helpful tips (different wax etc) so she can continue with waxing treatments? Thank you (thought I should add that she has not been taking roaccutane for years but her facial skin is very thin)
