If you've been using acne-targeted skincare to treat it, you might want to take a break as long term use may cause adverse effects to your skin. look for skincare that's aimed at calming/ repairing/ hydrating your skin (I recommend moisturizers as in can serve as 2-in-1 function, especially since you're a student and I understand you may not want to spend too much money on skincare). you can use acne products as spot treatments only. :)
oh yeah also, you can't change the size of your pores but you can lighten the look of it. meaning make it look like it's not so big 😅 if I'm not wrong, some clay masks does that as it takes away the impurities within your skin, making your pores clean and appear small.
change of lifestyle if you have yet to try :)
Like sleep by 11pm as after 11pm you are considered as pulling a all nighter.
Sleep at least 8h per day, and not to over sleep as well.
Change of diet to clean ones , need not do Everyday or all.
Stick to only 2L of water per day
Exercise to detox too...U Can find online
Best to see doctor at National
For shallow to mid-depth scars, they’ll most probably prescribe Stieva-A or Retacnyl. This are strong-ish creams and must use strictly according to doctor’s instruction. The more “ice-pick” (ie deep scars) ones may have to do laser to get rid of it. It is a very long process to recovery (depending on the recovery rate of your skin) but be patient.
Most products marketed for acne are not really helpful. You can try finding products with AHA/BHA in it, they can help with pores. The underlying propensity to develop acne cannot be cured, the only effective ways to reduce the chance of acne forming is to see a doctor for antibiotics or oral isotretioin. You are only 17, it is likely that you can still face acne issues for at least the next 10 years. Source: I am a specialist trainee in Dermatology.
