But seriously, what difference does it make to the jocks if they have problems with their skin? It is worth starting not from someone else's state, but dealing with your own. There are many reasons for stretch marks, but few solutions. Firstly, creams for stretch marks do not help if they are already there. Secondly, cosmetic procedures do not help much either. Stretch marks are deep damage to the skin. They can occur when there is not enough collagen. It is worthwhile to understand the reasons, to take blood tests. Stretch marks themselves are not dangerous, but they can be symptoms or worsen over time. Take some time for yourself, this is important.
Who said that jocks have normal skin? Almost everyone has stretch marks, especially on the biceps and in the armpit area. It's just that the dbuilders who perform at all sorts of competitions carefully mask them with special paint (if you can call it that), actors and models hide them with tattoos or spend crazy money on cosmetic procedures.
