If I can give this product no stars I would. I love medik8 retinal. So I thought I would try this vitamin c plus it’s a low dose even better WHEN I TELL YOU MY SKIN BROKE OUT IN PAINFUL LUMPS ON THE 3 day and I don’t break out like that ever I had the worse reaction plus redness, itchy irritation on my face I should of took pictures my skin is was so bad first time in my life my skin reacted so badly to a product Also I don’t think it’s the vitamin c that caused this because vitamin c isn’t known to clog pores or irritate skin it’s the other ingredients that’s used in this product maybe that caused a bad reaction Now I’m left with marks to deal with I’m so annoyed

[I received this product in exchange for my honest review] This packaging is so cute ! I love me a good vit C and it’s perfect for any skincare routine for men and women. I am loving this brand alot ! No harsh chemicals and sees like very good ingredients .
[I received this product in exchange for my honest review] I gave this guy 30 days before writing my review, to truly give it a chance. Here’s what I found: Pros: •smells nice •the bottle feels sturdy and nice •the serum is thin and easy to spread Cons: •I didn’t really see much clarity in dark spots, or radiance in overall skin complexion •very oily, would have to constantly wash my hair because it never fully absorbed into the skin •found that the concentration was too mild •did irritate the area around my nose folds. •applicator is messy. You can squeeze the droplet but once you’re done, it’ll still drop product without trying. •personally did not find it worth the value Overall, I think I’d skip this. I’d go for something much higher, I’d wear a bonnet at night to protect my hair, and I’d skip around the nose. I didn’t see results from this but again, it’s probably the low concentration of vitamin c. this might be great for someone with clear skin, or someone younger looking to add a vitamin c product to their routine.
[I received this product in exchange for my honest review] As a serum oil, this was difficult to wear during the day because it is very oily. However, on days at home or at night, it’s an intensely moisturizing, vitamin c brightening packed option to target sun damage. Your skin will not be dry with this on. Received for free in exchange for my honest review on Influenster.
[I received this product in exchange for my honest review] This vitamin C serum is great for sensitive skin. It’s non- irritating and absorbs well. Be careful not to apply too much or it can feel a bit oily. The dropper dispenses the serum too easily, it almost flows right out so, again, be careful. It has a slight scent, sort of like tea tree oil, which I’m not a fan of. But the scent goes away pretty quickly. In the few weeks I’ve used the product, I’ve noticed my skin looks a little brighter and my dark spots have lightened as well.
I absolutely love this stuff. It smells absolutely fantastic and usually oils leave me feeling gross but thankfully this does not!! It absorbs in pretty nicely and leaves my skin feeling nice and soft and glowing!
[I received this product in exchange for my honest review] Been using this product every morning since receiving. It has left my skin feeling my brighter and moisturized. I have enjoyed using and will continue to use in my morning skincare routine.
[I received this product in exchange for my honest review] Love these drops. Work wonders on my skin. Leaves my skin feeling healthy and smoother throughout the day. If you’re wanting to take care of your skin pick some of these Medik8 drops!
[I received this product in exchange for my honest review] The C-Tetra Serum is very light to the touch, absorbs quickly into the skin, and makes my skin glowy afterwards. I especially enjoy the light fragrance!
[I received this product in exchange for my honest review] I've been using this serum for a while now, and it's honestly become a staple in my morning routine. It gives your skin that effortless, healthy glow without any of the stinging or irritation that usually comes with vitamin c products
