Testimonials

Made a huge difference

I am very impressed with this serum, it has really smoothed out the fine lines and firmed up sagging areas. the only thing I found unfortunate was the applicator was faulty and would not suck up the product. So I would stab it in then smear on my face as needed. The complete change in my skin since using the product was remarkable.

Kelly

New Firmer Face

The Boost Serum has definitely helped reduce wrinkles and fine lines. I feel like it has firmed my skin and my complexion looks more boosted and refreshed overall. I can feel it working as soon as I put this on my face and neck. I love this product and will continue using it.

Clarissa

A Boost for your skin

I found the Boost Lab Elastafirm a great product & it has smoothed out my skin & given it a dewy complextion, my fine lines are still there but maybe a tiny bit less. It is easy to apply. You only need a small amount so it would last quite a long time, overall I would recommend this product.

Donna

Happy Skin

This serum was such a joy to use. The texture was silky smooth and a great consistency that absorbed into my skin so well. The scent was so mild I hardly noticed it. After using for a few weeks my skin feels firmer, smoother and really quite silky. I feel like I almost have a little glow to my skin. This is definitely a product I will be repurchasing.

Sharon

Boost Lab Collagen Firming Serum is Best

I have been using Boost Lab Collagen for roughly 3 months. I and many of my friends have noticed that these has been less wrinkles and my face feels tighter. I was shocked cause many of the serums I used don't actually work which leave me disappointed especially when they are $50 for 20ml. Would recommend to all my friends and family!!!

Sonia

Collagen Firming Serum

Wow, I was sceptical at first and didn't think I would notice any difference. I have been using this Boost Lab Collagen Firming serum morning and night for the last 6 weeks. There is a slight scent to it, but nothing overpowering. You do not need much which is great, a little goes a long way. My face absorbed it so well, my skin took it in as if it was thirst quenching. My face felt softer and hydrated at first. Then after a couple of weeks I had a few friends mention how my face was glowing, I did notice that it looked healthier. With continued use it soaks in beautiful and has given me a plump look effect. I will continue to use this, even after 6 weeks of using, I have about a quarter of this bottle left. I have felt there has been an improvement with the look and feel of my face. I definitely recommend trying if you have been looking into it.

    A really nice serum

    I really liked this serum. My skin felt really soft and smooth after using it. It has a nice cooling feel when you put it on and it’s absorbed quickly. A little goes a long way!

    I really enjoyed using this product. It was easy to use with the applicator and a little product went a long way. The scent was quite pleasant and smooth and easily absorbed into my skin. My face felt radiant after using this product for an extended period of time. I would highly recommend this product.

    Great product, used 2x a day for 6 weeks

    I really love this serum. I currently have very little left, which makes me a little sad, because I feel like it is doing good for my skin.

    I used it morning and night after washing my face. During the day, under sunblock or foundation, it did not pill or make my face feel heavy and oily. It absorbed well into my skin and made my skin feel smooth.

    I love that it did not feel sticky or oily on my face and blended well with SPF and foundation.

    I would buy this again with my own dollars.
