Medik8 C-Tetra review

I have recently started adding a Vitamin C serum to my morning routine. As many skincare experts say,  Vitamin C is a key to maintaining a smooth, even, and glowy complexion. What I also love about Vitamin C serum is that it is safe to use in conjunction with other skin care products, including lactic acids, retinols and SPF. To target the signs of ageing, shield the skin from the pollution and restore the radiance, youth and elasticity, I choose Medik8 C-Tetra serum. Its silky-soft formula is lightweight, quick absorbing, with no or minimal irritation and an uplifting natural citrus aroma.
