Love this Bundle!
First of all, I absolutely Love Cosrx! It is one of my top favorite Korean skincare brands! I will never be without the 6 peptide Skin booster! It feels so good on the skin and soaks in really quick! the skin booster doesn’t have a smell at all. Now I really like the vitamin C serum I’m actually on my second bottle that I have bought from Cosrx! It does have a weird smell, and you have to keep it refrigerated so that it doesn’t lose all its goodness. It works really well too I’ve notices some softening of my dark spots but its not drastic, but I don’t use it every night either. I am acne prone, so I like to rotate my skincare especially with that much vitamin c. If you do not refrigerate it, it will start becoming a darker color and the smell gets a little stronger. I read that’s because it is losing its potency. The price to get both these products in this bundle together is so much better than buying them separately. Using these products together make my skin so pretty! I only use the Vitamin c at night, but I use the peptide booster every single day, day and night. I had a bad bout of acne a year or so ago and cosrx and Korean skincare literally saved my skin! both are very effective and not too harsh on my skin. I am defiantly buying more soon!

Great for skin brightness and uneven skin tone
Great product. The set lives up to its promises for brighter skin and even skin tone, my skin is firmer, and hydrated. I’ve gone through 3 sets. it does last a long time when used properly.

This is part of my every day routine day and night! Peptide serum is the best part
The peptide serum is an absolute game changer and highly recommend. The snail stuff is OK. I don’t use it as much, but I can definitely tell you. I’ve been using this peptide serum for a few months now and have definitely noticed changes and decreased wrinkles. Better hydration even skin tone will be purchasing

Light, absorbent, and soothing
The peptide serum was very light, more of an essence in consistency than a serum. This is a lovely product, and it has definitely upped my nighttime routine. Snail products are my favorite, and adding the peptides alongside the mucin serum has kept red spots at bay

Ok product but smell is weird
Peptide serum was thinner than expected. Don’t think it will be like the snail mucin. It is light but soothing. The vitamin C serum is a little crazy, out of the bottle it smells like cat food/tuna tbh but when it rubs in it doesn’t smell like anything. It’s moisturizing & made my skin feel nice. Still not sure if I’ll repurchase.

Love Cosrx
I have already been a big fan of Cosrx snail mucin – it’s inexpensive and the bottle lasts a very long time – you don’t need much. This calms my rosacea and just hydrates my skin nicely. I ordered this set on an Amazon deal.This is my first time to try the ceramides serum. The texture is thin but not watery, and is a tad sticky after applying. I don’t mind the sticky feeling as I am used to that with other skincare, like Coxrx vitamin C can be sticky. It soon absorbs. Just don’t apply too much.I have experimented with applying the ceramide serum before and after snail mucin but prefer snail mucin first. Sometimes I apply the ceramide towards the end of my routine, others early on. Some ‘rules’ in skincare are absolute and need to be followed, but I have found that you can be flexible and experiment with others.I’d reorder the ceramide serum, and of course the snail mucin. The only thing with ordering the kit of both is you will run out of one before the other but it’s a great way to try them together.

BEST SKINCARE LINE EVER!!!
BEST SKINCARE LINE for my sensitive, acne-prone skin…. I’ve been using COSRX for about 6 months now and NOT turning back. I’ve never use to have such acne-prone skin until I started doing jiujitsu. My old skincare line wasn’t cutting it and I had to change it up… I’m SOOOOO HAPPY I took the risk on spending money on COSRX cause it literally brought my skin back to life. AND if you’re curious what COSRX products I use, here it is— AHA/BHA toner, peptide booster, 23% vitamin c, 2% alpha arbutin discoloration serum, 0.5 retinol, eye cream, & snail 92 all-in-one cream. The only (2) NON-cosrx products I use is my daily cleanser & BHA exfoliating scrub
