[I received this product in exchange for my honest review] While I can see a difference in some areas if my face, this serum is too heavy for my pores to use regularly. I found that my skin breaks out and throws off my regular skin routine.
[I received this product in exchange for my honest review] Absolutely love the c-tetra luxe it has left my skin so smooth and bright. It is so soft and clear. There is no residue has cause me no irritation whatsoever and was not oily in my skin
[I received this product in exchange for my honest review] It has shown good results so far but I had to cut down on the amount of drops it says to use on the bottle because using the recommended six drops left my skin looking and feeling extra oily.
I’ve loved using this product. It’s absorbs quickly and has barely any scent. I had no irritation or sensitivity when using it. I’ll be adding it to my short list of Vit C to repurchase.
[I received this product in exchange for my honest review] I really liked the texture of the product. My skin felt hydrated and glowy but not greasy. It was lightweight and was easy to rub in and my skin felt soft for most of the day.
I really like this serum. It absorbs super quickly and leaves a perfect base for a rich moisturizer. My face looks smoother overall
[I received this product in exchange for my honest review] I enjoyed using this serum! It’s comparable to skinceuticals! It’s lightweight, easy to layer and doesn’t pill under other products. My skin looks healthier overall and has a healthy glow. I need to use it longer to see how it helps with dark spots. Overall, works well and is a great price point!
[I received this product in exchange for my honest review] I’ve been using Medik8 C-Tetra Luxe every morning before sunscreen, and I’m loving what it’s doing for my skin. The lightweight serum absorbs quickly, feels amazing, and has a soft citrusy scent that makes my morning routine feel a little more luxurious. My skin feels noticeably softer, smoother, and firmer, and I’ve started seeing an improvement in my fine lines and wrinkles. I love how fresh and healthy my skin looks after using it, and it gives me that extra boost of confidence before I head into my day. Definitely a new favorite in my skincare routine!
[I received this product in exchange for my honest review] The Medik8 C-Tetra Luxe serum is unscented. Even when using a minimal amount, it felt heavy and left a sticky/slime-like residue. Wearing makeup was almost impossible without looking and feeling like a total cake-face. Someone with drier skin may benefit from this product more than an oily girl like me.
[I received this product in exchange for my honest review] I really did like this! Feels like a high end vitamin c and performs like one. Never pilled with my skincare and makeup, felt like it really soaked into my skin. My only complaint is it definitely feels more like an oil than a serum. Well, that and the price.
