Why You'll Love This Serum

  • Hyaluronic Acid — a moisture-binding superstar that draws hydration into the skin for a plump, dewy, youthful appearance throughout the day.
  • Collagen-Supportive Formula — formulated to help accelerate the skin's natural collagen production process, contributing to firmer, more resilient-looking skin over time.
  • Lightweight Oil Texture — absorbs quickly without a greasy finish; suitable for layering under moisturiser or SPF.

  • No High-Concern Chemicals — free from high-concern chemical ingredients for a cleaner skincare experience.

Frequently Asked Questions

Q: What does the TRSTAY Niacinamide B3 Facial Serum do for my skin?

A: The TRSTAY Niacinamide B3 Facial Serum combines Vitamin B3 (Niacinamide), Vitamin E, and Hyaluronic Acid to help even out skin tone, hydrate deeply, and support the skin's natural collagen production process — resulting in a visibly smoother, firmer, and more radiant-looking complexion with consistent use.

Q: Which skin types is this serum suitable for?

A: This unisex, lightweight oil serum is formulated to be suitable for all skin types. Its quick-absorbing texture works well for dry, combination, and normal skin, and its non-comedogenic Hyaluronic Acid base keeps skin hydrated without feeling heavy.

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

A: The 5 mL size is perfect if you'd like to try the serum before committing to a larger bottle. The 15 mL and 30 mL options suit regular daily users, while the 50 mL bottle offers the best value for those who have already made the serum a staple in their skincare routine.

Q: Can I use this serum with other skincare products?

A: Yes! Apply the serum after cleansing and toning, then layer your moisturiser on top. In the morning, always finish with a broad-spectrum SPF. Niacinamide pairs well with most skincare actives, making it an easy addition to any existing routine.
