Frequently Asked Questions

Q: Can I use the Vitamin C Essence and Retinol Essence together in the same routine?

A: Yes! A popular approach is to use the Vitamin C Face Essence in the morning to take advantage of its brightening and antioxidant properties, and the Retinol Face Essence in the evening to support overnight skin renewal. This allows both essences to work at their most effective time of day without interfering with each other.

Q: Is the SUYARUN Face Serum Duo suitable for sensitive skin?

A: Yes — both essences in this duo are formulated with low-irritation ingredients and are described as suitable for all skin types, including sensitive skin. If you are new to Retinol or Vitamin C, we recommend starting with every other day use and gradually increasing frequency as your skin acclimates. Always patch-test before full application.

Q: How long before I can see visible results from using the duo?

A: Consistent daily use is key. Many users begin to notice improvements in hydration and skin texture within 2–4 weeks. Firming and brightening benefits typically become more visible after 6–8 weeks of regular use. For best results, use both essences as part of a complete morning and evening skincare routine.

Q: How long does each bottle last after opening?

A: Each essence has a recommended Period After Opening (PAO) of 12 months. For optimal freshness and efficacy, store the bottles in a cool, dry place away from direct sunlight and ensure the caps are securely closed after each use.
