Frequently Asked Questions

Q: What makes the TRSTAY Retinol 2.5% Facial Serum different from lower-concentration serums?

A: The TRSTAY Retinol 2.5% Facial Serum delivers a professional-grade concentration of retinol, which is significantly higher than many over-the-counter serums typically offering 0.25%–1%. This means you get a more potent dose designed to accelerate visible skin renewal, smooth texture, and improve overall radiance with consistent use.

Q: Can beginners use a 2.5% retinol serum?

A: If you're new to retinol, it's best to introduce the serum gradually — start by applying it two to three nights per week and build up frequency as your skin adjusts. Always follow with a good moisturiser and wear SPF the next morning, as retinol can increase your skin's sensitivity to sunlight.

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

A: Yes! The TRSTAY Retinol 2.5% Serum is formulated as a unisex product suitable for a wide range of skin types. However, those with very sensitive or reactive skin should patch-test first and consult a skincare professional if unsure.

Q: When will I see results from using this facial serum?

A: Visible improvements in skin texture, tone, and radiance are typically noticed within 4–8 weeks of consistent use. For best results, incorporate the serum into your nightly skincare routine and pair it with daily sun protection.
