Is the collagen booster effective for men's skin?

I am writing to inquire because I am curious if collagen boosters are effective for men's skin. I usually don't do much skincare, but lately my face looks so dull and lacks elasticity, so I am looking into cosmetic procedures for the first time.

Perhaps because it is men's skin, I have a lot of sebum but feel dry underneath, and the corners of my mouth often feel tight after shaving. In particular, when I take photos, my face seems to sag compared to before, and my cheeks look dull, making me feel older.

Collagen boosters have an image of being primarily for women, but do men also frequently consult about them? If the effects of a collagen booster focus on improving skin texture and elasticity, I am wondering if it is suitable for someone like me with thick, oily skin. I also want to know if the treatment makes the face look naturally healthy rather than overly shiny or obviously artificial. I would also like to inquire about when I can shave after the procedure and whether the recovery burden is too heavy for a male office worker. Please help me!
