How To Use
After washing your face and toning your skin with lotion, gently press the dropper head to dispense an appropriate amount into your palm and gently blend into your skin with your fingertips. Apply to the entire face, excluding the area around the eyes, focusing on areas with dullness. It is recommended to use within two months of opening. Store in the refrigerator after opening. *Please avoid using with other products that are highly irritating.

I love this serum so much that I've lost count of how many times I've repurchased it!! I like that it's gentle enough for daily use while still feeling the effects of vitamin C. Storing it in the refrigerator can be a bit of a hassle, but the cool feeling when you apply it is lovely! Personally, I don't mind the smell that much. With continued use, I've stopped noticing things like enlarged pores and freckles! In short, it stabilizes the condition of my skin. This is a serum I would recommend to anyone thinking about starting a vitamin C serum.
It works on sagging skin.
I've been using COSRX's Full Fit Propolis Synergy Toner for a while now, and this one came with a set, so I used it and finished the whole bottle. It has a unique scent and stickiness, perhaps due to the concentration of ingredients, but I apply cream immediately afterwards, so it didn't bother me too much. I didn't experience any noticeable skin irritation or dryness during use. It's a little pricey for the amount, so I'd like to continue using it if I have the chance.
How to use and precautions: Use after washing your face as a serum. It has two layers, so shake gently before use. Once opened, use within two months. It is best stored in the refrigerator. It was a transparent yellow color and had a smooth texture. It didn't feel sticky at all. It had a unique vitamin scent, but it wasn't too strong and I didn't mind it, so I was able to use it until the end.
I bought this as a morning serum. The scent is a little strange, but I have sensitive skin and it works fine. It says to store it in the refrigerator after opening, so I keep it in the refrigerator.
