When I got home I read the post treatment care leaflet, and have looked online and see that ANY sun seems to lead to hyperpigmentation problems. Do you think it is likely with the sun exposure walking home? I'm quite nervous.
We must consider skin after peels as thinner than it normally is therefore all beauty professionals always applying high spf after treatment. I personally advice my clients to not to go to swimming pools as chloride in the water can irritate the skin.
Typically after a peel of any kind one should not expose their skin to direct sun light for any long periods of time. This should have been explained to you by your professional with your aftercare instructions. I hope however, that sun protection was adequately applied to your skin, post peel.
