You have a skincare routine you've spent months perfecting. You switch products, try new things, build habits. But nobody sees it. It lives in your bathroom, in your head, in a Notes app screenshot you sent a friend once.
Meanwhile, everyone on Reddit is asking "what's your routine?" and you're writing the same comment for the fifth time. Your shelf is a museum. Where's the guest book?

Your shelf has a story
Every product you add builds a community database. Every routine you share helps someone else find what works. This isn't content creation — it's just being honest about what you use.

Finally found a retinol that doesn't make me peel like a snake. Added tretinoin 0.025% to my PM routine and my skin has never been this smooth. 62 days in. 🔥

Cloned @priya's double cleanse routine and I'm never going back. The Banila Co + La Roche-Posay combo is chef's kiss. Day 12 and my pores are visibly smaller.

"I've been waiting for something like this. Every skincare app feels like a doctor's office. This feels like it was made for people who actually love beauty."

"The Letterboxd for beauty comparison sold me immediately. I want to log my routines the same way I log films. And the dark mode aesthetic? Perfect."
James L.
6-step routine · Committed
