Frequently Asked Questions

Q: What does the TRSTAY Vitamin C Face Serum do for dark spots and freckles?

A: The TRSTAY Vitamin C Face Serum is formulated with a brightening Vitamin C complex that targets melanin overproduction — the root cause of dark spots and freckles. With consistent use, the serum helps visibly lighten and fade these areas, promoting a more even and luminous skin tone across the whole face.

Q: Is the TRSTAY Vitamin C Serum suitable for sensitive skin?

A: Yes! The TRSTAY Vitamin C Face Hydration Serum is designed as a unisex formula suitable for all skin types, including sensitive skin. It contains no high-concern chemicals, making it a gentle yet effective option for daily skincare use.

Q: How long does it take to see results from the Vitamin C Face Serum?

A: Skincare results vary by individual. Many users begin to notice a brighter, more hydrated complexion within 2–4 weeks of consistent daily use. For best brightening and dark spot–fading results, we recommend applying morning and evening as part of a complete skincare routine.

Q: Can this serum be used under makeup or SPF?

A: Absolutely. The lightweight, fast-absorbing texture makes the TRSTAY Vitamin C Serum an ideal base layer under your daily moisturiser, SPF, or makeup. Allow the serum to fully absorb for 1–2 minutes before applying the next step in your routine.
