I am in my seventies and still try to look after my skin, which has a tendency towards dryness, in the best possible way. I find the Replenish Collagen Boosting Serum moisturising, giving me a feeling of comfort, without being too heavy underneath my usual moisturiser and foundation. It is also quite economical to use. Obviously I have developed lines and wrinkles over the years, but I feel that the products I use are helping to keep them at bay.

Smooths skin and feels enriching yet light under my usual moisturiser. Better than other serums I have used. Lovely product to use and not tested on animals.

I love this serum, silky smooth and skin feels better, more hydrated. I have also noticed that because I am post menopausal I started to grow a few whispy hairs on my face, these seemed to be fairly non existent since using this serum, I cannot put it down to anything else. I don't know if any other users have noticed this.

We are pleased to hear how happy you are with the replenish collagen boosting serum.

Very pleasant, light cream. Will order again.

It's great to hear you are pleased with the Replenish Collagen Boosting Serum.
