Frequently Asked Questions

Q: Can I use both the Vitamin C and Retinol serums at the same time?

A: It's generally recommended to use the Vitamin C serum in the morning to take advantage of its antioxidant properties during the day, and the Retinol + Hyaluronic Acid serum in the evening as part of your nighttime routine. This helps maximize the benefits of each formula without layering them simultaneously.

Q: Is the HISENRAIN Serum Duo suitable for sensitive skin?

A: The HISENRAIN Serum Duo is formulated for all skin types, including sensitive skin. However, if you have particularly reactive skin or known sensitivities, we recommend doing a patch test on a small area of skin before full application. If any irritation occurs, discontinue use and consult a skincare professional.

Q: How long before I see visible results from the Vitamin C + Retinol + Hyaluronic Acid Serum Duo?

A: Consistent daily use is key. Many users begin to notice improvements in skin brightness and hydration within 2–4 weeks. More significant improvements in skin texture and the appearance of fine lines are typically visible after 6–8 weeks of regular use.

Q: Is this serum combo safe to use during pregnancy?

A: Products containing Retinol are generally not recommended during pregnancy. Please consult your healthcare provider or dermatologist before using any new skincare products while pregnant or nursing.
