Mary Kay Lash and Brow Building Serum

The purpose of the Mary Kay Lash and Brow Building Serum is to improve the look of lashes and brows by helping them to look thicker and fuller. There is nothing on the Mary Kay information page that suggests that this product will improve the growth of eyebrows nor does it suggest the hairs will become stronger.

The serum works in two ways: it nourishes the skin around in the area where hair is produced and it protects the area so it has the best chance of growing healthy hair. It adds amino acids to the skin for the nourishment process and uses red clover extract which contains antioxidants and these help to neutralize free radicals which might shorten the life cycle of the hair.

This is all about the appearance of the eyebrows and the way in which they appear to look after the lash and brow building serum has been applied. According to the company you can expect to see results after 30 days of continuous use of the product.

An applicator brush is supplied with the product which can be used on both the eyelash and eyebrow area.

The filler comes in a 0.15 fl oz tube along with an applicatorand the recommended cost from the company is around $38.00 however it is commonly available at a much lower price.

Customer Reviews

“I have been using Mary Kay Lash & Brow building Serum sporadically for 10 months, and I noticed a difference almost immediately. My brows have filled in, although I don’t think they will ever become as full as when I was in my 20s and 30s. For me, the product works better than anything else, and I will continue using it.”

“I’ve been using this diligently for a little over a month and I honestly haven’t noticed a difference in my lashes length or thickness. I’m kind of bummed but not surprised. I will continue to use this product until it runs out and then I will start using a homemade castor/coconut/vitamin e oil concoction that I found on Youtube.”
