Frequently Asked Questions

Q: Can I use the Vitamin C Day Serum and Retinol Night Serum together in the same routine?

A: Yes! The SUYARUN 2-in-1 duo is designed specifically for this purpose. The Vitamin C Day Serum is best used in the morning, and the Retinol Night Serum is formulated for evening use. Using them at separate times maximizes the benefit of each ingredient and avoids any potential sensitivity from combining them at once.

Q: Is this serum suitable for sensitive skin?

A: The SUYARUN Vitamin C & Retinol Serum is formulated for all skin types. However, if you have particularly sensitive or reactive skin, we recommend doing a patch test before first use and consulting a skincare professional if you have any concerns.

Q: How long before I see visible results?

A: Consistent daily and nightly use is key. Most users begin to notice a brighter, more even-toned complexion within 3–4 weeks of regular use. For more significant visible improvements in skin texture and firmness, continued use over 8–12 weeks is recommended.

Q: Do I need to wear SPF after using the Retinol Night Serum?

A: Yes. Retinol can increase your skin's sensitivity to sunlight, so it is important to apply a broad-spectrum SPF moisturizer every morning after using the Retinol Night Serum to protect your skin.
