## Description

Crystal Drop CLEAR Blink Lash Eyelash Extension Coating Sealant Aftercare Product

Review: LASH EXTENSION SEALANT - I was skeptical about this at first, but it actually made my lash extensions last much longer than expected. Super easy, I use it like a mascara once in the morning and again before bed, and I bought it over a month ago but I’m probably only about 1/4 of the way through the bottle, so it’s lasting me a long time. Even using it before a shower hasn’t irritated my eyes. It’s lightweight, doesn’t leave behind a lot of buildup or goop or take long to dry, and doesn’t feel harsh or cause my lashes to clump. I’m really impressed with how well it works. Happy with it!
Review: Multi purpose! - This is great for putting over top of mascara to achieve a less clumpy look... stream lines the mascara nicely. I found a new use for it now that lash extensions aren’t an option with all the salons closed/pandemic

## Features

- PROTECTS YOUR LASHES | What a topcoat nail polish does for a manicure that’s what BL Crystal Drop lash sealant does for lash extensions. It forms a barrier around your delicate extensions, protecting them from oil, water, and sweat
- THIN, SEAMLESS FINISHING | The texture of the Crystal Drop Lash Extension Sealant is thin and non-sticky. It doesn’t clump up on eyelash extensions but helps elongate and correct weak, uneven, thin lashes
- EYELASH GROWTH | Unlike other cosmetic products, a BL lash sealant is a water - soluble, oil - free, functional lash extension aftercare product that prolongs the retention of lash extension. It comes with an easy-to-use mascara-type brush that gives a fuller look to your lashes
- LONGER RETENTION | This Overnighter Lash Sealer forms a coating barrier on your eyelash extension and makes your eyelashes last for a longer period
- HOW TO USE | Apply it evenly on the eyelash. Once applied, brush your lashes well with a dry lash wand. You can use lash coating sealant on volume lashes, too. Just make sure you brush them thoroughly with a fresh mascara brush. Avoid applying this lash overnight sealer to the part where the lash glue is used if applying to your client’s fresh lash set

## Questions & Answers

**Q: Is this safe for sensitive eyes?**
A: Apply only to lashes — avoid direct eye contact. Patch test recommended for sensitive users.

**Q: My lashes felt stiff / crunchy after using it.**
A: You may have applied too much. A single thin coat is all you need — the formula is concentrated.

**Q: Will Crystal Drop leave white residue?**
A: No. Apply to dry lashes in a thin layer and comb through. Dries completely clear.

**Q: Is Black Diamond really black or just watery?**
A: Shake well before every use. The pigment settles — 10 seconds of shaking restores full color.
