I was surprised how good

"I was surprised how good this serum is. I thought it might be difficult to apply but it certainly isn’t and it dries very quickly. It gives a lovely, subtle glow and seems to help my rosacea prone skin too. I also really like the No5 Tan Mousse but the No. 17 serum works best on the face for me."

amazing products for my skin :o)

"I started using just the face glow serum and anti aging night cream which I love. I saw this serum with tan and was intrigued seeing I can never tan my face and with 70 spf I use my face is always white compared to my body. I just started using this in with the first application (which was very easy) I saw natural boost of color and my face did look nice with no other face tint needed. I am so happy and just saw the anti-aging tan serum and will try this one also. I feel like I could use this year round but not apply as much for a nice winter color to my face! Thank you for all your amazing skin products! Even the tanning cream leaves me with great lasting color which looks so natural and fades like a real tan! Ty xoxo"

Great product for rosacea sufferers

"I’ve recently started using the No. 17 glow serum and just wanted to say how much I like it. I have rosacea but this serum doesn’t aggravate my skin at all. It’s very easy to use, dries quickly and just adds a subtle healthy glow without looking too brown. The No. 5 Tan Mousse is also very good for the body."

Ok but not great

"The product doesn’t really deliver as described. My skin felt dry after using it and to be honest I didn’t get the glow I was hoping for with only achieving a slight colour change. I was expecting a light tan so I could use less foundation but this sadly didn’t happen even after using the product 3 days in a row."
