I am a 23 year old female, 57 kilos, i got a second degree sunburn four days ago, i stopped taking my retin a medication a year ago and not currently taking any medication.. I was perscribed oral cortancyl 20mg for three days and a deep moisturizer to be applied three times a day.. The burn is on my legs, thighs, arms, chest and tummy. It doesnt hurt anymore but still very red and not peeling yet.. Im very afraid it will scar! Will it?
