Will I pay customs or import fees?
US orders: No. As of July 1, 2026, all US orders ship DDP (duties delivered prepaid), meaning we prepay all import duties on our end. Nothing is due at your door.
Orders outside the US: Possibly. Duties and import taxes are set by your local customs authority and are not collected at checkout, so any charges on delivery are your responsibility.
We're working on rolling out prepaid duties for more countries soon.
When I first started using it, I wasn't sure how good it was, so I left it for a while. However, I recently started to worry about fine lines due to dryness, so I started using it again (only at night), and the next morning my skin felt plumper and the fine lines were less noticeable. I immediately bought a refill and also bought one for my younger sister, who also suffers from fine lines due to dryness. I didn't particularly mind the smell. All I have to do is apply my own lotion or cream to it, and I'm done.
It has a smooth texture and only a small amount can be applied to the entire face. After continued use, the fine lines around my eyes have become less noticeable. It's relatively inexpensive, so I'll definitely be buying it again.
It has a slightly thick, slightly opaque texture. The moment you put it on your face, it soaks into your skin! It's great that it moisturizes without needing to apply a lot! However, I didn't like the scent. It smells a bit like nail polish remover. The scent is the only thing that's disappointing.
It has an alcohol-like scent, but it disappears quickly so it's not a bother. It's a great product because it's affordable and can help with fine lines.
