BL Lashes Crystal Drop
Best for professional lash techs and hobbyists seeking a clear, waterproof shield that helps retention without changing lash color. The Crystal Drop offers a brush-type sealant to guard against moisture and oil while preserving adhesive strength. Suitable for clients requesting a discreet finish and reliable wear.
Best used with standard lash adhesives; avoid over-application to prevent gloss buildup on lash roots.
BL Lashes Black Diamond
Best for clients who want a darker lash-line finish resembling mascara. The Black Diamond sealant provides a dark, mascara-like look and extended fill longevity while maintaining a waterproof barrier. Choose this for clients seeking a pronounced finish; caution: may appear visible if over-applied on very light lashes.
Super Bonder for Eyelash Extensions
Best for professionals seeking a rapid-setting booster that works with any adhesive. This Bonder acts as an accelerator and sealer, maximizing retention up to about 30% and helping lashes stay put after wet exposure. Caution: designed for professional salon use only; avoid self-application or use with clusters.
Stacy Lash Primer
Best for pre-application prep to maximize adhesion. Stacy Lash Primer removes oils, makeup residue, and dust to provide a clean bonding surface, improving retention. Practical for techs maintaining a kit of prep supplies. Limitation: results depend on proper surface preparation and adhesive compatibility.
FADVAN Lash Sealant
Best for DIY lash projects seeking a light, transparent barrier that extends retention up to about two weeks. The sealant is thin and easy to remove with standard lash removers, making it suitable for removable or trial applications. Use with cluster lash glue for best results; avoid heavy layering that can feel stiff.
Buying Guide: Key Considerations For Sealants For Eyelash Extensions
- Finish and appearance: Clear versus dark finishes; mascara-like finishes can alter lash appearance and are best for clients wanting a defined look.
- Retention goals: Some sealants are optimized for short-term coatings (days to two weeks); others aim for longer wear with waterproof properties.
- Compatibility: Ensure compatibility with your primary lash adhesive and any primers you use to avoid chemical conflicts.
- Application method: Brush-type applicators offer quick, even coats; droppers and built-in droppers help control amounts for prep steps.
- Professional versus DIY: Some products are labeled for professional salon use only; follow these guidelines to maintain safety and warranty.
- Removal: Consider how easily the sealant can be removed or softened during lash removal sessions without affecting natural lashes.
- Safety and skin contact: Look for non-irritating formulas; if you or your client has sensitive eyes, test a small area before full application.
FAQ
- What is a lash sealant and why use it?
Answer: A lash sealant forms a protective barrier around the lash adhesive, reducing moisture and oil exposure, which can improve retention and reduce premature shedding. - Can sealants replace a lash primer?
Answer: No. Sealants and primers serve different roles. Primers prep the natural lash surface for adhesion, while sealants protect and extend retention after application. - Is a dark finish better than a clear finish?
Answer: It depends on client preference. Dark finishes give a mascara-like look, while clear finishes are discreet and maintain natural lash color. - Are sealants safe for sensitive eyes?
Answer: Use products labeled as gentle or formulated for sensitive eyes and perform a patch test as needed. - How should sealants be applied for best results?
Answer: Apply a thin coat over sealed areas after adhesive curing, following product instructions. Avoid over-application to prevent gloppy or sticky buildup. - Should sealants be used daily?
Answer: Use according to client needs and product guidelines. Some are designed for longer wear, while others are better for frequent touch-ups.
