It’s so silky & smooth. Really hydrating. I love it & so do my friends :)
I have used this serum for a year and a half! It’s honestly amazing. Need it in a bigger bottle I go through so much. The high Vitamin C content has changed the way my skin heals and rejuvenates itself. It also gives my skin an amazing glow. Love love love this product.
I have been using this for about 2 weeks. It is lovely and light and reduced my inflammation around my eyes.
This is an excellent serum. It’s probably the lightest one they have so best in summer or if you are oily. I actually like to use if I have to wear a lot of makeup as I feel like it makes my skin look the best. I also like to use it if I look a bit red as it seems to really take it back to neutral.
This is my 4th bottle of BK - I use it on my face every morning. It really is as good as it reads! I’m a tad over 60, have sensitive skin and the product has pronounced benefits on the overall texture and lines on my skin.
