Me as a guy myself , try not to think from other's perspective nor it be a women or men which thinks that skincare is only for female .
You will have to put aside every judgment from others about how weird it is for a men to use skincare . If you keep on thinking about other's judgment or opinion about a guy using skincare , you will never be confident.
However , try not to treat those who judge your skin by attacking them . Examples are "At least I dont have acnes like you" , " Your skin looks so old and ugly and saggy for a teen" . The moment you attack them about their skin because they judge you first , you are literally equal to them . Literally just ignore them. HOWEVER , IF THEY NONSTOP JUDGING YOU THEN YOU MAY DEFEND YOURSELF AND ATTACK THEM 😆🤣
