Frequently Asked Questions

Q: What is lactobionic acid and how does it benefit my skin?

A: Lactobionic acid is a polyhydroxy acid (PHA) derived from lactose. It is a gentle exfoliating and hydrating ingredient that helps visibly minimize the appearance of enlarged pores, smooth skin texture, and boost moisture levels. Unlike stronger acids, it is suitable even for sensitive skin types, making the TRSTAY Lactobionic Acid Facial Serum a versatile choice for a wide range of users.

Q: How often should I use the lactobionic acid pore serum?

A: For best results, apply the serum once or twice daily — in the morning and/or evening — after cleansing and before moisturizing. If you have sensitive skin, start with once daily and gradually increase as your skin adjusts.

Q: Which size should I choose – 5ml, 15ml, 30ml, or 50ml?

A: The 5ml size is great for travel or first-time users wanting to try the TRSTAY Lactobionic Acid Serum before committing to a larger bottle. The 15ml and 30ml sizes are ideal for regular use, while the 50ml offers the best value for those who have already made it a staple in their skincare routine.

Q: Is this facial serum suitable for all skin types?

A: Yes! The TRSTAY Lactobionic Acid Facial Essence is formulated for unisex use and is compatible with oily, dry, combination, and sensitive skin types. Its lightweight, pore-purifying formula makes it an excellent addition to any daily skincare regimen.
