my skin aways has a defect that makes me avoid where any kind of short sleeved dresses or spagetti tops.because if i wear these ,i will start itching myself due to which there are red spots on my skin and i know its not because of any mosquitoe bite, as we use mosquito repellant for keping them far away.then when i told this to my elder sister she told me to go for Olux .is there any product in Olux that caters to skin irritation?and if there is ,is there any precaution that i need to take before using any product of Olux?
