Great serum

Illume serum

Makes my skin look tighter, fresher and glowing. I’ve also noticed my pores appear smaller. Generally best thing I’ve encountered for my skin in years. Friends are asking me what I’ve been doing.

Bought this along with the hydrate serum and awaken eye cream. I have not yet tried the illume but if the others are anything to go by, it’ll be lovely.

Mixed thoughts

I wanted to love this serum and although it left my skin lovely and soft, it was too much for my blemish prone skin and brought me out in pimples.

My favourite serum ever

I love this serum so much - it goes on beautifully and leaves skin hydrated and firm. I prefer it to other, more costly serums. I never want to be without this product!

Magic in a bottle

I’ve never used Niacinamide before, having read all the wonderful benefits it gives the skin I purchased the Illume and haven’t looked back, (on my third bottle). Smooth the fine lines, plumps and hydrates, my skin is so much clearer with a lovely glow. I have sensitive/reactive skin and I’ve had no issues using this daily. Sinks in quickly leaving no oily/sticky residue. Fragrance free which I love. This one’s a keeper for me.

Everyone should use this

Niacinamide does wonders to your skin, and this serum does not let you down. Smooths and softens skin. I alternate mine with the hydrate serum. Both recommended
