Which ingredient should be avoided in eyelash extension adhesives?

Formaldehyde is a known irritant and can pose serious health risks when used in products that are applied close to the eyes. It can cause allergic reactions, respiratory issues, and skin irritation. In the context of eyelash extension adhesives, the potential for formaldehyde to release vapors can be particularly hazardous in a setting where clients are often in close proximity to the adhesive and may be sensitive to chemical exposure.

While silicone, latex, and alcohol may have their own considerations in cosmetic applications, formaldehyde is generally recognized as a substance to avoid in eyelash extension products due to its potential effects on both the user and the client. This makes it essential for eyelash extension specialists to choose adhesives that do not contain formaldehyde, ensuring safer and more comfortable experiences for clients.
