Many reasons I love Biologi products so much. Their components are natural, the active ingredients are native, the effects on the skin and long term and durable, they simplify instead of complicate skin care, and now, even better, the bottles can be returned!! I'm a loyal costumer! Love
I love Biologi serum and my skin has never felt and looked better.
I’m 62 and have been using Bk and Bm along with Roship Oil for some time now and my skins looks great and feels so hydrated. Thank you Biologi
It’s only been about two weeks but I can already see some improvements with softening of fine lines around my eyes and mouth and skin feels more hydrated. Looking forwards to seeing what 28 days brings! I am 53 so seeing any improvement at all has been a bonus after trying other products with big promises that have never delivered for me,.
I have been using Bk for almost a year, and it is easily the most effective undereye treatment I have ever used. I am still in my 20s, so I mainly use it preventatively. I did have the beginnings of some small lines under my eyes, but they were gone within a few weeks after starting Bk. It also helps with undereye puffiness. I have a very sensitive undereye area, and this product has never irritated my skin! I haven’t used it as a multipurpose face serum yet, but I love that I have the option!
Vitamin C as a strong antioxidant is so important for our daily protection (free radicals, pollution etc.) that’s why my morning starts with Bk (all over my face+neck) followed by the sunscreen. Immediately it evens the skin tone and makes it look healthier and very soft. Most importantly, all Biologi serums (Yes i purchased the whole range and I'm using all of them, alternating am and pm ) sink into the skin perfectly and absorbs quickly, so in a couple of minutes you are ready to put on sunscreen and enjoy the day...
