Really oily

So oily. I don't recommend this at all if you don't like oily products or your skin looking oily/greasy.

Medik8 C-Tetra

I have been using this serum for a few weeks now but haven't seen significant results yet. It has nice texture and the skin feels smooth and soft but other than that I don't see how it works.

Hate it

1 stars out of a maximum of 5

I did not like this. I had no idea it would be so oily. My skin looked so oily after using it and I don't have oily skin I have normal or dry skin. Maybe this is more useful for people who can tolerate oils on their face but my skin didn't like this at all. i had more uneven texture and my pores looked bigger than ever before. I can imagine it works for some people, but make sure your skin can tolerate an oil/oily product before you try it.

I would repurchase

5 stars out of a maximum of 5

I love using the Day cream from medik8 with vitamin c and spf30. But for days where I need a stronger spf, I have purchased this serum. A little goes a long way, it smells amazing. Not really sure about results, but my skin is looking the healthiest and radiant since I started using medik8 products in my daily routine!
