Why Klira works for me
"I've been interested in retinoids for a while, and tried a few. What makes Klira exceptional to me, is the bespoke prescription delivered by subscription plus ongoing online medical support which helps me to commit to the programme for the months required, and then to notice real change in my skin tone, look and feel. Really excellent quality products too, enjoyable to use. Nice joyful packaging too :)”
Friendly, informative & amazing product!
"My experience with Klira has been nothing but friendly and supportive! I love the online quiz to assess your skin type & concerns, so they can send you products with the correct dosage and ingredients for your skin - makes it accessible for everyone! My personalised skincare product arrived within days and the packaging is so easy to use, the product felt like it really penetrated the skin, and the bottle looks super cute on my bathroom shelf. Dr. Emma’s zoom consultation was extremely warm, informative and helpful. I finally feel like I have the right products to nurse my skin back to health.”
I’m so happy with the results!!
"I am always on the look out for anything to give my skin that healthy and dewy glow. I am always sucked in by celebrity endorsements and flash packaging but normally without the promised results. I have absolutely fallen in love with klira. From the simplicity of the routine to the end result, I couldn’t be happier that i tried this. It’s great to know that I am in the best expert hands with Dr Emma’s wealth of knowledge and to top it off I’m not being charged an astronomical amount (the price point for the products is amazing!) Thanks so much for ending my constant flitting from one product to another. I have had such a lot of compliments about my skin and will be sticking firmly to the routine!”
Great results!
"I have always been very dedicated to my skincare regime (and easily sucked in by good branding…) so I was so excited to find Klira and what it offered for my skin. The best thing about the Klira Special is that it is so carefully tailored to your skin and the knowledge that you are in such safe hands with Dr Emma and her amazing team of expert dermatologists - they are always on hand to give advice when needed. I love the simplicity of the regime and the results have been great too - I hadn’t realised how great until a few people commented on my glowing skin!! So exciting not to have to find time to exfoliate any more too! Thank you Klira!”
Skincare routine I will finally be loyal to!
"I ordered online and this was so easy to do! Have been using a few weeks every night along with my lovely cleanser, day cream and suncream that was recommended just for my skin. Someone said to me my skin was looking great and that to me the results I needed. I also feel like my skin is looking and feeling great with a really healthy glow. Can’t wait to see how it continues over the months.. love Klira, skincare I will finally sticking to!!!”
Simple with fabulous results
"I’m a bit of a skincare addict and have always loved trying new products, and been prepared to spend a fair bit on luxury brands to try and get the best results. But as my skin has got older (I am 40) I’ve found that nothing was really having the desired (or promised!) effect. What I LOVE about the Klira Special is that I know that this is the very best treatment for MY skin. I don’t have to shop around any more and spend money on products that don’t really work! The supporting routine is so simple. And most importantly, my skin hasn’t looked this good in years… it’s really glowing and I haven’t had a single hormonal spot and I’m only 6 weeks in! I can’t wait to see the results over time. Thank you Klira!”
As an older person with very sensitive…
"As an older person with very sensitive skin I have really appreciated the help and guidance given by Dr Emma and her kind team. The product is personalised and formulated for me and consequently I have been able to tolerate it and feel the benefit. Klira Dermatology Team have responded promptly to queries and provided expert support. Highly recommend.”
