Give your moisturiser a boost :)

5 stars out of a maximum of 5

I’ve been using the peptide serum in my AM routine for a few weeks now and it really compliments the vitamin c moisturiser. Cold weather and aircon usually dry my skin out but this combination has really made a difference and my makeup stays fresh all day

My favourite serum

5 stars out of a maximum of 5

I’ve tried a few serums but this one is the best I’ve found for my skin. Great packaging and a little bit goes a long way.  I find it’s really good for layering and doesn’t cause makeup to pil.

Love this

I only recently started using the medik8 brand and I love this also. Great feel on the skin and really smooths the skin. Sinks in very fast too.
