FAQ:

Q: Is this a serum or a sleeping mask? A: Both—it’s a serum-like product designed to be used as an overnight mask (last step at night).

Q: Can I use it every night?
A: Yes, it’s designed for daily hydration support, especially if your skin is dry or dehydrated.

Q: Will it feel sticky?
A: It’s made to form a moisture barrier with a non-sticky finish. If you apply too much, use the “thin layer + second layer only if needed” method.

Q: Is it suitable for sensitive skin?
A: It’s described as low-irritant and hydration-focused. If your skin is very reactive, patch test first.

Q: Can I use it in the morning?
A: You can, but it’s best as an overnight product. In the morning, use a smaller amount to avoid feeling too layered under makeup.

Q: What should I pair it with?
A: It pairs well with gentle toners/serums and a moisturizer. If you use strong actives (acids/retinoids), apply this after them to help reduce dryness.
