Am freaking out! Been using 1 % obagi retinol for about a week. The nurse told me to use it every other night and use factor 50 each day which I have been doing. It was hot here yesterday and I had to be somewhere where there was no shade at lunchtime so was in the sun for about an hour. My face feels burnt today but actually isnt looking burnt at all ) just a tiny slight bit of redness round my marionette lines. Have I damaged my skin?! I am using Obagi to clear up my adult acne and it has been great doing that but feels so burnt and uncomfortable and like am damaging it? I am also thinking about getting a 'vampire facelift' (the plasma needling therapy) but I now think I may actually go for botox instead after this experience, as we are in the Summer and am scared about the damage to my skin? What do you all think? :-)
