I have naturally really long eyelashes, but I always think they are not very thick! I have been sent a product by beautytrix, it's called Flirties, it's an eyelash enhancing serum that is ment to give you fuller, thicker and longer lashes in weeks.
It says to apply twice daily for 12-16 weeks until eyelashes have reached maximum length, then reduce to using it 2-3 times a week. This is there tip for maximum results. I haven't been using it for 12 weeks, but I have definitely noticed a difference in the thickness of my lashes.
Usually I don't really believe in serums like this, but after trying it my faith has definitely changed, I didn't notice a result until about 1.5-2 weeks in, but I think that's because it took a while to stimulate growth.
A 3ml bottle costs £19.95 which on a teenagers budget is a bit pricy, but if your eyelashes need to be either longer or fuller, I think it's worth it.
My lashes, are thicker and fuller and I'm very impressed with the result!
You can get a bottle of this from beautytrix.
Have you tried any serums?
