What skincare product are you lowkey obsessed with right now?

What's something you keep reaching for lately because it actually seems to be doing something? Could be a moisturizer, serum, toner, sunscreen, cleanser, literally anything. I'm trying to switch up my routine a bit and find stuff that's actually worth repurchasing, mostly for hydration + smoother-looking skin. Curious what everyone's using rn and what difference you've noticed.
