I repeatedly buy this facial serum because I have the impression that it really works. It doesn't irritate my skin in any way, it pumps it with hydration and smoothes it out. I also use it around my eyes. Really, just three drops are enough for the entire face.

Though it’s not cheap, but you can see the difference after one use, combining the exfoliation, serum & face mask. 

I got this in Luxury Box, it is wonderful being able to try such a great product. I hope I have the chance to get another one this year!

I got this product from my Cult Luxury Box last year. I bought the box for this product as my wife uses this serum at night. She loves Bioeffect range as it is effective and gentle enough on the eye area. Only 3 drop for the face and neck area. The anti aging effect won't be quick but long term use one will start to notice. She said as this serum is water based, she love it even more, as she can lock in her serum with an oil based serum after. The texture is light, not much scent to it and gentle on the skin.

I started using this serum last year after it became too expensive to import the growth factor serum I had previously been using.  I found it spreads easily, isn’t sticky and left my skin feeling hydrated and healthy. I did find I needed to use a moisturiser after it despite the brands claims that the serum on its own is enough- I tried using the serum alone but developed dry patches on my cheeks. I feel like it’s definitely a long game with these serums, you’re not expecting an immediate miracle but rather waiting for the anti-aging results down the line! I will always restock. 

I have to say, the serum I've been using is hands down the best product I've ever tried. While it's definitely on the pricier side, it has completely changed my skin's pigmentation and removed scars. I've even seen the effects overnight, and the science behind the product really works for me.

This in incredible. It works instantly, skin is more glowy and plumper. I'll probably wait for a sale to treat myself to it again though;)

I tried it from the CB luxury edit, and it’s one of the best serums I’ve ever tried. It felt so good on my dry sensitive skin, and it help a lot to “normalize” it. Next morning the skin would feel so soft and smooth even on retinol days. And it lasts for quite a while, even considering it’s small size, just 1-2 drops is enough for the whole face, so it lasted me for almost 3 month of daily use. I’m usually not easily impressed by expensive serums, but this one is definitely worth it cost/quality wise, as I never tried any cheaper serum that’d give even remotely similar results 

I got the full size of this serum as a part of Cult Beauty Skin Edit. I wanted to try the serum for a long time. Now I have almost used the 15 ml, and say it's a dream. You need only two drops in the evening for the hole face. It is very delicate, I use it on my lids and under the eyes. The skin is hydrated, looks little bit firmer... Yes, I will purchase the next bottle.

I've tried a lot of face products and this is the product with the best results so far. Downside -it's a bit sticky.
