Let customers speak for us
Love it!! Its not hardh and drying. Love the feel after washing with it.
Hi I love the retinol 0.3%serum. I am using it for a few years already. One of my darkspots are gone after using it continously.
This is my HOLY GRAIL.
If you're new to Skin Functional, this product HAS to be in your cart!!!
At least this oneeeeee.
Especially if you have sensitive, dry skin with hyperpigmentation like me.
If you have oily skin I highly recommend the 10% niacinamide.
I ordered my PDRN serum on Thursday as part of black Friday vip access, and received my free makeup brush set, and the dispatch notice on Friday! Fantastic service
My all time favourite. Can't live without it. Great on its own, a nice hydrated clean feeling, or as part of a double cleanse
I love this primer. I've never used a primer before, and I don't wear makeup, but this just gives my skin a nice, soft, filtered glow. My skin but better
On my second bottle and hmmmm thank God for trusting the reviews skin is popping and glowing and the pores have minimized in just 10 weeks of use .a girls bestie this one
I have eczema and this is Amazing and not harsh on my skin at all.
Having used a few Vitamin C serums over the years, I can really recommend this one. No nasty smell, perfect texture for my dry skin, and leaves my skin feeling moisturised. I bought the small bottle to test and have reordered as I notice an improvement in my skin texture. An excellent product!
Being new to true skincare, this product changed my life. My pores have reduced in size within a few weeks. I have now ordered the 10% Niacinamide Serum so I hope it does what the 5% did for me in a few weeks. Love this product and can't imagine not having Niacinamide as part of my skincare routine at all
All I can say is THANK YOU. Every time I buy from your website, its easy and I know that I will get my products in record time
I heard everybody talk about the hydration juice and I just had to get my hands on it! Now, I can't take my hands off it! Absolutely love this product and won't go without it ever again. My (mature) skin feels so hydrated and since I have been using it, I literally can't imagine going without it ever again :)
i have been using it last 4 weeks, very happy with it, its gentle, absorbs well, and calms the skin beautifully
