Cozy Whitening Tone-Up UV SPF42/PA+++ Medicated Whitening Tone-Up Emulsion for the Face and Décolleté, offering whitening care while blocking UV rays. A subtle pink color with fine pearls. A non-chemical formula that is resistant to rubbing and can be removed with soap. My Thoughts: The subtle pink color with fine pearls brightens the décolleté, making it look even brighter, and blends well with the skin. It spreads easily and has a natural finish, which I love. It also highlights the often-forgotten décolleté, so I'll be using it regularly from now on.
I was suffering from rough skin, and was looking for a primer that wouldn't strain my skin, and I was attracted to the glycyrrhizin in it, so I bought it. [Good points] It brightens the skin tone with just one application. It spreads easily, and I was able to hide my skin imperfections to some extent with just this and powder. [Concerns] I had to pat it in firmly in areas where pores were more noticeable. I didn't notice any particular effect on rough skin. It wasn't unpleasant to use, but it wasn't so good that I couldn't live without it!
It contains pearl and gives a slight pinkish tint to the skin. It's not sticky so you can apply it to your décolleté too.
So far it hasn't stained my clothes, so that's good! I mostly work indoors.
I use sunscreen all year round, but using multiple primers for my sunscreen was a hassle, so I decided to buy this one, which has both toning and sun protection! It spreads easily, is thin, and applies evenly without smearing, and it really brightens the entire skin tone, which I really liked!
