New skin.

[This review was collected as part of a promotion.] I’ve used ren skin care products for years now and have tried most products for my skin as it changes through the seasons, first time using the marine moisture serum. Leaves my skin rehydrated and glowing.

Great product

Originally posted on REN Clean Skincare

[This review was collected as part of a promotion.] The consistency is just right. A small amount goes a long way. My skin looks much better and hydrated. I find this to be the best of any serum I’ve tried.

Fabulous feeling skin

Originally posted on REN Clean Skincare

[This review was collected as part of a promotion.] This serum has a lovely consistency and absorbs leaving a cool feeling. Lightly scented it gives great results leaving skin soft and moisturised. I mix and match this with my overnight cream when my skin needs a little extra comfort

Better serums available

Originally posted on REN Clean Skincare

[This review was collected as part of a promotion.] The smell, texture and consistency of this serum is great. However I'm finding this product fails to leave my skin feeling as hydrated or supple as other serums I have used.

Part and parcel of a good regime.

Originally posted on REN Clean Skincare

Whilst I am using the Vit C products mostly I do use this serum every other night in this winter weather and in and out of heat. It plumps my skin well. I had been following another regime for some time but my skin was stressed from a move and a little neglected and I started using the Radiance products and within no time at all my over 65 skin came back to life with extra benefits of lightened age spots.

Amazing serum for thirsty skin

Originally posted on REN Clean Skincare

I love this serum, it’s lightweight, silky and smells fresh. Blends really nicely with the ever calm range products too. Discovered that it’s a great primer before makeup, which I didn’t expect.

Nice but not suitable for my rosacea

Originally posted on REN Clean Skincare

I tried this serum for a change rather than my usual Evercalm as it said suitable for sensitive skin. It is a watery texture and sinks in really well. It doesn’t make my sensitive skin itch but did bring out the redness in my rosacea, it might be as it has fragrance. Unfortunately not for me so I went back to evercalm

Interesting

Originally posted on REN Clean Skincare

First time user of this product, mature skin. A little goes a long way and gives my skin a more even tone. Takes a smidgen longer to soak in but so far, pleased with firming effect, not dramatic but would consider buying again.

This serum really helps keep my skin deeply moisturised and fresh looking. It is light weight and soaks in quickly before applying my moisturiser.

It’s good but not sure how much difference it makes to my oily but dehydrated skin. My husband (very dry skin) likes it.
