Comforting winter skin x

[This review was collected as part of a promotion.] I have a tendency for rosacea. Having used Pai products I know their benefits. This serum has not disappointed. It smells delicious and is making a difference by comforting and hydrating my sensitive skin which doesn’t like winter change.

[This review was collected as part of a promotion.] I have come to really trust this product; I can tell if I’ve had a break from using it. I tend to let it sink in for a few minutes then use The Anthemis moisturiser and my skin feels calm and nourished.

No more red, angry blotchiness for me

Originally posted on Pai

[This review was collected as part of a promotion.] This is a fabulous product, from the first time I used it my skin was calmer, cooler and didn;t cause a redness flare-up, best of all, it doesn't cause itchiness/burning. My skin is reactive so it usually goes more red as I add products but this has been a game changer, my skin is still red but a little less red than it was a few weeks ago, definitely an improvement.

Miracle in a bottle

[This review was collected as part of a promotion.] The difference that this lightweight serum added to the anthemis moisturiser has made to my winter wind reddened face is nothing short of remarkable. Thank you Pai for a brilliant combination of products.

My skin is very sensitive

Originally posted on Pai

[This review was collected as part of a promotion.] My skin is very sensitive and I have psoriasis so always cautious to use new products, particularly serums. However my skin had no bad reaction at all, and if anything it soothed it. Hard to tell if it’s this specific product or the combination I’m using (serum, the anthemis and rosehip oil) but I’ve definitely seen an improvement in my redness and plaques, particularly on my face. My only negative is the serum and moisturiser combination do leave my skin feeling quite dry, so end up using a fair bit of the moisturiser (it isn’t cheap!) and sometimes have to use an organic balm from another brand that seems to lock in moisture a little better.
