Frequently Asked Questions

Q: What makes YOUNGCOME's 20% Vitamin C Serum different from other Vitamin C serums?

A: The YOUNGCOME Vitamin C Face Serum combines a high-potency 20% Vitamin C concentration with Hyaluronic Acid and Retinol — three of the most effective skincare actives — in a single oil-based formula. This multi-ingredient approach targets multiple skin concerns at once: brightness, hydration, texture, and the visible appearance of fine lines and wrinkles.

Q: Can I use this Vitamin C serum every day?

A: Yes! The YOUNGCOME face serum is designed for daily use. For best results, apply it in the morning and/or evening after cleansing. If using during the day, follow with an SPF moisturiser, as Vitamin C can make skin more sensitive to sunlight.

Q: Is this serum suitable for all skin types?

A: This serum is formulated for women and is suitable for most skin types. If you have particularly sensitive skin, we recommend doing a patch test before full application. The Hyaluronic Acid component also makes it beneficial for those with dry or dehydrated skin.

Q: How long will it take to see results from the Vitamin C serum?

A: Individual results may vary. Many users begin to notice brighter, more even-toned skin within 2–4 weeks of consistent daily use. For more significant improvements in texture and the appearance of fine lines, continued use over 6–8 weeks is recommended.

Q: Is the YOUNGCOME Vitamin C Serum CPNP certified?

A: Yes, this product holds CPNP (Cosmetic Products Notification Portal) certification, which is an important quality and safety credential for cosmetic products.
