What it is
This serum creates a highly adhesive barrier that seals in moisture, protecting the skin for hours, and keeps skin fresh and smooth. It focuses on the fact that even with thorough skincare, the skincare effects and moisture can be lost over time. By applying it at the end of your skincare routine, it locks in the moisture and skincare effects in the skin. It also integrates with each stratum corneum cell to maintain the skincare effects and protect the skin from external factors such as dryness. A fresh, smooth gel that is not sticky and feels comfortable on the skin.

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.
It's neither dry nor sticky, and has just the right feel. It leaves your skin feeling smooth and smooth after use. It comes with a spatula, which is hygienic. There's no place to store the spatula, so it's easy to lose it. It's almost scentless. The ethanol smell might be a bit bothersome, but it doesn't sting.
I thought the light texture would be good for summer. I tend to focus on aggressive skin care, but I think IPSA products are good for defensive skin care, so I would like to stock up on them along with the Time R Aqua lotion and the ME series emulsion.
It doesn't feel super moisturizing, but I have combination skin that is prone to dryness, but if I try too hard to moisturize I get acne, and I also have sensitive skin that doesn't agree with many products, so I can't live without it because it moisturizes without any problems.
