Frequently Asked Questions

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

A: Absolutely! The 2-in-1 set is specifically designed to complement each other. Use the Vitamin C serum in the morning to brighten and protect your skin, and the Retinol serum at night to support renewal and a smoother appearance. Together, they provide around-the-clock skincare benefits.

Q: Is this serum suitable for sensitive skin?

A: Yes, the SUYARUN formula is designed for all skin types, including sensitive skin. However, if you have specific skin concerns or a history of reactions to Vitamin C or Retinol products, we recommend doing a patch test first and consulting a skincare professional before regular use.

Q: How long will it take to see results from the Vitamin C and Retinol Serum?

A: Consistent daily use is key. Most users begin to notice improvements in skin brightness and texture within 4–6 weeks of regular morning and evening application. For optimal results, use continuously as part of your skincare routine.

Q: Does the Retinol Night Serum make skin more sensitive to sunlight?

A: Retinol can increase skin's sensitivity to UV exposure. It is recommended to use the Retinol serum only at night and to apply a broad-spectrum sunscreen during the day to protect your skin.
