Is this safe for sensitive eyes?

Apply only to lashes — avoid direct eye contact. Patch test recommended for sensitive users.

My lashes felt stiff / crunchy after using it.

You may have applied too much. A single thin coat is all you need — the formula is concentrated.

Will Crystal Drop leave white residue?

No. Apply to dry lashes in a thin layer and comb through. Dries completely clear.

Is Black Diamond really black or just watery?

Shake well before every use. The pigment settles — 10 seconds of shaking restores full color.

Great sealer

I recommend this product because my lashes fall off very easy and I have to go back every two weeks and so far nothing has fell off so I do recommend this product immensely

High Quality Product

I absolutely love this product! One of the most unique features is the bottle does empty at the end of use! Therefore, you use every bit of product. Always shake well before every use! Very good for individuals with sensitive eyes! Hope this helps!

Extends my lash life between refills dramatically

I go for a refill every 2 weeks. Before using this, 90% of my lashes were gone by refill time and it took 45 minutes or more for my 2 week refill. Now, around 40% of my lashes remain at refill time and refills are taking 30 minutes.
