Product Overview

BL Lashes Black Diamond Lash Sealant is a professional-grade, brush-on formula designed to maximize the retention of your eyelash extensions. Whether you're a lash artist or a DIY enthusiast, this sealant creates a protective waterproof barrier that locks in curls and keeps extensions looking fresh for up to four weeks. The innovative black diamond pigment adds a subtle shimmer that enhances the natural look of your lashes, making them appear darker and more defined.

Key Features and Benefits

  • Extended Retention: The advanced polymer formula bonds with the lash adhesive to prevent premature shedding, helping extensions last up to 4 weeks.
  • Waterproof Coating: Creates a durable, water-resistant seal that protects against humidity, sweat, and tears, so your lashes stay flawless all day.
  • Brush Type Applicator: The precision brush allows for targeted application along the lash line, ensuring even coverage without clumping or sticky residue.
  • Black Diamond Pigment: Infused with micro-fine black diamond particles that add depth and a natural luster to your lashes, making them look fuller and more vibrant.
  • Safe and Gentle: Formulated without harsh chemicals, this sealant is safe for use with all types of lash extensions, including synthetic, mink, and silk.
  • Easy to Remove: When it's time for a refill, the sealant dissolves effortlessly with a gentle oil-based remover, leaving no residue behind.

How to Use

After your lash extensions are applied and the adhesive is fully cured (typically 24 hours), apply a thin layer of Black Diamond Lash Sealant along the base of the extensions using the brush. Start from the inner corner and work outward, coating the lash line where the extension meets the natural lash. Avoid getting the product on the skin or into the eyes. Allow the sealant to dry naturally for 30 seconds. For best results, reapply every 2–3 days or after each lash bath. Use only with professional lash extensions; do not apply directly to natural lashes.

Who It Is For

This sealant is ideal for lash technicians who want to offer clients extended wear, as well as individuals who wear lash extensions and want to maximize their investment. It's especially beneficial for those with oily skin or active lifestyles, as the waterproof formula resists breakdown from natural oils and moisture. Perfect for brides, travelers, or anyone who wants their lashes to last longer between fills.

Why Choose This Product

BL Lashes is a trusted brand in the lash industry, known for high-quality products that deliver professional results. The Black Diamond Lash Sealant stands out because of its unique black diamond pigment, which not only seals but also enhances the appearance of your lashes. Unlike other sealants that can leave a white residue or feel sticky, this formula dries clear and leaves lashes feeling soft and flexible. Plus, the convenient brush applicator makes it easy to apply at home or in the salon. With a 0.24 fl.oz bottle, you get approximately 60 applications, making it a cost-effective solution for maintaining beautiful lash extensions.
