Just ok

3 stars out of a maximum of 5

I was dubious about this as I have combination skin so stopped using any oil based or cream like formulas a few years ago and switched to serums which seems to have  had a huge positive impact on my skin. But the reviews are good and it’s a fraction of the cost of my usual SkinCeuticals CE Ferulic so thought I would try it. In comparison I would say it’s just ok, good option if on a budget but I’ll be going back to SkinCeuticals when my bottle is finished, even if the price is eye watering. The results compared to this make it justifiable. I’d rather cut back on other things but be safe in the knowledge that my skin is as well looked after as it can be.

Absolutely love this product, my skin is glowing since I start using it. Its also a plus buying it from lookfantastis for a fraction of the price I was paying for it from elsewhere.

Silky soft skin!

5 stars out of a maximum of 5

This is a sumptuous, lightweight, silky-soft serum that packs a punch. Application is a dream; unlike other serums that I’ve used in this price range, this isn’t tacky and doesn’t leave my skin feeling tight. It’s smooth, gives my skin an instant boost and leaves it feeling soft and radiant. I leave it on for 20 minutes and let it absorb fully, before applying moisturiser. The smell is citrus-like but not overwhelming. A word of warning - it has a very thin, “watery” consistency, so don’t drop the bottle or you’ll have nothing left!

Love the consistency of the Medik8 C-Tetra Serum. It's a light weight oil that absorbs quickly to the skin. Perfect for busy morning that you just want to slather everything on your skin and get going.

Fab serum

5 stars out of a maximum of 5

This serum is absolutely gorgeous v light weight and absorbs really quickly neutral smell. After two weeks of usage my hyperpigmentation appears alot lighter then when using other expensive serum that claim to lighten spots. Also the price point is amazing I got this on LF sale for 21 quid....! A total bargain...I will definitely be trying the medik 8 tetra intense (30 %) one after this... But this is a great buy I would re purchase this in a heartbeat as it's reasonable and definelty effective for hyperpigmentation for me.
