Unclear if it's helpful

I bought this after my aesthetician recommended adding peptides to my routine. The overview says it prevents signs of aging and deeply hydrates skin, but I can't really tell that it's doing either. To be fair, I already use a Vitamin C, sunscreen, pigment corrector, and retinol, so maybe my skin looks as young as it's going to? And my skin is generally oily, so the deep hydration isn't really necessary. I like that it's a very light and clear serum, so it goes on easily, but I'm just not sure I'm the target market. I'll keep using it til the bottle is empty, but for now, I think I'm just not the right audience for it.
