Hi
You seem to be having acne which is common at your age. However if you are getting too many black marks after the acne you may be picking at or squeezing the acne or having too much sun exposure. Please use a salicylic acid face wash twice a day. Use a gel based sunscreen to protect your skin. Avoid using baking soda as it is alkaline and tends to dry out your skin and make it go darker
