📋 目次
1Is COSRX niacinamide serum suitable for all skin types?
Yes, it works well for most skin types including oily, combination, and sensitive skin, though it's particularly beneficial for acne-prone and congested skin. If you have very dry skin, you may want to layer it with a richer moisturizer to avoid any tightness.
2What's the difference between the Advanced Snail 96 Mucin Power Essence and the niacinamide serum?
The niacinamide serum (Pure Fit Cica Cream or the Advanced Hydra Toner) focuses on pore control and sebum regulation, while the snail mucin is primarily hydrating and soothing. They serve different purposes, so many people use both in their routine.
3How long does a bottle of COSRX niacinamide serum last?
A standard 100ml bottle typically lasts 2-3 months with daily use since you only need a small amount per application. The exact duration depends on how generously you apply it and whether you use it twice daily.
4Can I use COSRX niacinamide serum with other active ingredients like vitamin C or AHA/BHA?
Yes, niacinamide is generally compatible with most actives, but introduce one new product at a time to monitor how your skin reacts. If you're using strong acids or retinoids, apply the niacinamide serum in a separate step to minimize irritation.
5Should I choose the toner or essence version of COSRX niacinamide product?
The Advanced Hydra Toner has a lighter, more watery texture and better hydration focus, while other formulations may be more serum-like and concentrated. Pick based on your skin's hydration needs and preference—oily skin may prefer the toner, while dehydrated skin might benefit from a serum texture.
