Frequently Asked Questions

Q: What makes Retinol 1% Serum in Squalane different from other retinol serums?

A: The TRSTAY Retinol 1% Serum uses Squalane as its carrier — a plant-derived emollient that is exceptionally lightweight yet deeply hydrating. Unlike heavier oils, Squalane is non-comedogenic, meaning it won't block pores, making it ideal for those who want the benefits of a retinol serum without the greasy feel. The 1% retinol concentration makes it a potent option for supporting smoother, more even-looking skin.

Q: Can I use this serum every day?

A: For those new to retinol, it is recommended to start by applying the serum 2–3 times per week in the evening to allow your skin to adjust. As your skin builds tolerance, you may gradually increase to nightly use. Always follow with a broad-spectrum sunscreen in the morning, as retinol can increase your skin's sensitivity to sunlight.

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

A: The 5ml size is perfect for first-time users or for travel. The 15ml and 30ml sizes are great for regular use, while the 50ml option offers the best value for those who have already incorporated this serum into their daily routine. All sizes contain the same potent 1% Retinol in Squalane formula.

Q: Is this serum suitable for sensitive skin?

A: The Squalane base is gentle and soothing, helping to buffer the retinol and reduce the likelihood of sensitivity. However, as with any new skincare product, we recommend doing a patch test before applying to your full face, especially if you have sensitive or reactive skin.
