I didn't think another serum was going to do anything for me. I've been on the anti-aging hamster wheel since I turned 61. Retinol, La Mer, vitamin C, the SkinCeuticals growth factor one everyone raves about. All fine. None of them touched the lines on my forehead. Three and a half weeks into this, I was putting on my mascara and noticed the horizontal lines across my forehead were softer. Not gone. Softer. That's more than any of the $180 serums did

I'm 48 and I've been using Korean skincare for six years now. This is genuinely the first new ingredient combination that's felt meaningfully different in the last three years. The crow's feet around my eyes are the first place I noticed — they used to crease into my concealer by midday and now they don't. My husband doesn't notice anything skincare-related, ever, and even he asked if I'd done something

Bought this because my esthetician told me to. She's 42 and said she'd been using it herself for two months and her forehead lines were visibly softer. I was skeptical because she sells services and this is at-home, but she showed me her before/after and it was real. I'm on week 5 now. The '11' lines between my brows are the most noticeable difference. They're still there, but they don't look like they're etched in anymore.
