I was burnt on saturday, while taking the prescription drug, accutane for my acne. I applied sunscreen twice in 4 hours but I guess it didnt help much I got pretty red and my face went really dry so I got onto the aloe vera and moisturiser straight away. I m a lot less red today. Below my bottom lip though is a lot whiter than the rest of my face, maybe because I used lip balm, I m a little worried about this as it is pretty visible Below my chin and the outer skirts of my lips are swollen and a little red, how long until this goes down?
