new moisturising strat?

[BM.]

from going to the gym, like many others, I have developed some stretch marks, mainly along my arms. because of this, I got myself a cream which supposedly helps stretch marks, however when I looked at the ingredients I noticed theres a few stuff which would actually make it a really good moisturiser, and I'm not sure if anyone has spoke about it on here. first of all it has collagen and elastin, which will both help skin as collagen will strengthen it and elastin will make your skin more elastic, helping with wrinkles. and for the actual moisturising part, it has argan oil, coconut oil, shea butter etc, including petrolatum which is in vaseline, something lots of people use for moisturising. I'm genuinely not sure if this is just a good idea no ones thought of, or if someone's already said it but I can't find it, or If it's actually stupid. thoughts? I might try it ngl, it'll help with the drying from my epiduo

this is the one I'm talking about ^
