A: Yes! The TRSTAY Lactobionic Acid Serum is formulated for unisex use and is appropriate for all skin types, including oily, dry, combination, and sensitive skin. Its gentle PHA-based formula makes it a great choice for those new to acid-based serums.

Q: How often should I use this pore-minimizing serum?

A: For best results, incorporate the serum into your daily skincare routine — morning, evening, or both. Always follow with a moisturizer, and apply sunscreen during daytime use to protect newly refreshed skin.

Q: Is this product part of a Korean skincare (K-beauty) line?

A: This serum is inspired by Korean cosmetics innovation and K-beauty skincare philosophy, focusing on effective yet gentle ingredients for visible, long-term skin improvement. It is manufactured in Mainland China.
