Q. Can I use vitamin C serum every day? 

This is a higher concentration of pure vitamin C, so it may come with skin irritation. We recommend you patch test the back of the wrist or on your neck before first use. It can be used daily; however, if your skin feels irritated, please apply the product less frequently before increasing the frequency. If your skin feels severely irritated, we recommend you use a moisturizer, but if your skin still feels irritated, please apply the product less frequently or stop using it.

Q. What should you not mix with vitamin C? 
Mixing with hydroxy acids such as AHA and BHA may cause skin irritation, so we don't recommend using them with vitamin C.

Q. What can vitamin C be mixed with? 
Tocotrienol, hyaluronic acid, ceramide, snail, Centella

Q. Do you put vitamin C before moisturizer?
Vitamin C is the best to use before skincare. If you first use a light water serum-type C serum and then cover it with a thick cream type, you can absorb more vitamins into your skin.  

Q. It has a strange smell. Is this normal? 
This serum does not contain fragrances. However, vitamin C, by nature, has a certain smell that does not affect the potency of the product.
