Apply nightly and start with a clean, dry face.
Use one dip of serum and swipe the flatter side of applicator to coat the entire brow area. Then, use one dip of serum + angle the pointed tip to apply along the top lash line.
Avoid the inner corner, waterline, and bottom lashes (upper application has the lower covered). Wait 1-2 min for serum to dry.
Don't apply makeup immediately after or skip days...that'll just delay your full, fluffy results.

It works
This works for me! I’ve seen noticeable growth in both my brows and lashes, I’m on my second tube now and will purchase again.

Not Very Effective
I have used this for around 6 weeks now. My brows have improved slightly but absolutely nothing has happened to my lashes at all. As well as the hefty price, it doesn’t even last close to 12 weeks to see whether it works or not and I certainly won’t be spending this much on a serum for my brows alone when there are other better known products (which also don’t have PGA in them) for a far more reasonable price and are known to last the course of time you need to see a difference. The brush isn’t great for the lash line, it’s too big. It leaves white crusted product on you in the morning. Honestly wouldn’t recommend to anyone.
