I am 19 years old and I've been noticing that this year I got a major amount of visible stretch marks. I know they're nothing to be ashamed of but they're getting really bad. I'm a healthy student, I got to the gym 5 times a week, I'm not overweight. I have developed stretch marks around my waist (purple), on my biceps (white), on my butt (white) and between armpits and chest (white).
I drink around 8 glasses of water a day to keep myself hydrated, I stopped taking hot showers since it can make the skin dry, I also only take one shower a day, and I apply coconut oil every night before I sleep. Yet recently I've gotten some tiny pinks ones between my arm and bicep.
Can anyone please advise me on how to treat these and how to prevent them from coming? It's a little embarrassing being 19 and not being able to take off my shirt or wear shorts. Cheers!
