Do anti-aging serums improve skin firmness and elasticity?

There’s so much hype around anti-aging serums claiming to improve skin elasticity and firmness, but it’s hard to separate marketing from real results. Some studies suggest ingredients like peptides or retinol can help over time, but results seem subtle and slow.

I’ve started noticing my skin feeling a bit less firm around my jawline and cheeks, and I’m curious if adding a serum could actually help or if it’s mostly placebo. For those who’ve used anti-aging serums consistently, did you notice a real difference in elasticity, or is it more about hydration and glow? Would love to hear your experiences before I invest.
