After cleansing, during the serum phase, shake the bottle lightly once or twice from side to side and apply a few drops to the skin. Use fingertips to gently massage and absorb the serum, starting from the inside of the face working towards the edges. For the first use, attach the enclosed dropper in the product package. Recommended to use within 2 months of opening due to active ingredient protection. Highly concentrated serum should only be used in the evening? NO! This serum can be used in the morning and/or afternoon. If applied in the morning, be sure to use with a SPF of 30 or higher.
Precautions: Gas can be generated due to the nature of vitamin C. When opening the cap, it may make a sound. With a specially designed cap to seal vitamin C, it can be safely stored by controlling the gas generated inside the container. If you shake it before opening, it may overflow, so shake lightly, from left to right after fastening the pipette. Extra room in the container has been secured for safe use. Vitamin C products are recommended to be used within 2 months of opening due to easy discoloration caused by oxidation. Keep it away from high temperatures and direct sunlight. It is recommended to be stored in the refrigerator when it is not being used every day after fastening the pipette. Keeping it refrigerated can help maintain the freshness of the vitamin C. KEEP REFRIGERATED (3~10C) *Please use immediately after purchase and store upright in refrigerator once opened.

Can this vitamin c be used on sensitive skin?
- Asked by Jak
- Official Answer By COSRX - Brand EngageThis product is suitable for all skin types. However, as it contains a high concentration of pure vitamin C, some may experience irritation.

Can it cause the face to peel?

If your skin feels irritated, please apply the product less frequently at first before increasing the frequency or mix with a moisturizer.Was this answer helpful to you

Decent enough product but the purge is bad
Received this for free from influenster and CosRX in exchange for my honest review. (Also wrote this review 6x because this website sucks) I wanted to love this so much!

Working miracles!
This stuff is making such a difference in my skin. I'm 43 with sun damage and melasma from my pregnancies. I use this every night, store in the fridge as directed and its working!!
Smells so bad
This stuff is extremely stinking. Other Vit C serums I have used in the past have actually smelled good. So it's a no from me.
Left skin glowing
I loved this serum. It felt great in my skin and didnt leave me feelibg greasy. I fid fibd that you cant apply directly to your face with the dropper. It immediately ran down and off my skin. I placed the serum in my palm then apply with index finger
Very Good Product
I am 61 and take very good care of my skin. I found COSRX about a year ago and now use 4 of their products. Yes, upon application this serum has a light odor but it disappears quickly. I use this product in the am followed by the snail mucin serum. At night, the retinol followed by the peptide serum. I use a few other brands as well but can say…expensive is not always better. Just depends on the individual. I have had no adverse reactions to any COSRX products and so glad I found them.
Undecided
Okay yes this product smells GROSS. but it has improved the uneven skintone on my face. Also i noticed weird orange tinting on my palms after i started using it? Not sure what thats about…
