I used the Gosh Growth Serum on two occasions. The first time I used it with the Growth Mascara, and now recently I just got the serum only. I just have to warn you that it might give you a burning sensation when applying it right after you’ve washed your face; so rather wait a while before applying to fresh out out the shower face. It works very well when used with the mascara, quicker than if you just use it by it’s self. However, Rapid Lash slays this product. But this is a budget purchase Rapid lash is a bit pricey. Just be patient with this and you will see the results.
