Frequently Asked Questions

Q: What is retinol 1% in squalane and how does it benefit my skin?

A: The TRSTAY Retinol 1% in Squalane Serum combines a highly effective 1% retinol concentration with squalane — a plant-derived moisturizing oil. Together, they work to visibly smooth skin texture, reduce the appearance of fine lines, and deeply hydrate, leaving skin looking brighter and more youthful with consistent use.

Q: Is this retinol serum suitable for sensitive skin?

A: Yes! Because the retinol is suspended in a squalane base — which closely mirrors your skin's own natural oils — this serum is generally well-tolerated by sensitive, dry, and combination skin types. If you are new to retinol, we recommend starting with a lower-frequency application (every other night) and gradually increasing as your skin adjusts.

Q: Which size should I choose?

A: If you're new to this serum, the 5ml or 15ml size is a great way to experience the formula. The 30ml and 50ml options offer excellent value for those who have already made this serum a staple in their daily skincare routine.

Q: When is the best time to apply this retinol serum?

A: This serum is best applied in your evening skincare routine. Apply after cleansing and toning, then follow with a moisturizer. In the morning, always use a broad-spectrum sunscreen, as retinol can make skin more sensitive to sunlight.
