The PLA Flex Adhesive is great for advanced lash artists, and is not an adhesive for beginners. Flex has a super wide range, working in 20-75% humidity. We have tested this adhesive at every humidity level, ensuring that it works in many environments. Flex can be a quick adhesive, curing at 0.5-1 second. We use clean raw materials and fast polymerisation, resulting in low fumes. Flex stays fresh longer before needing a new drop during your appointments. Flex adhesive should never be frozen or kept in a refrigerator.

PLA’s Flex Adhesive has a treated bottle, allowing no fumes to be emitted. This increases the shelf life and leaves a safer adhesive for both lash artists and their clients.

Each bottle has been batch tested for safety by an independent toxicologist in the UK for grades to meet EU cosmetic regulations. We test each batch to ensure consistency and performance are maintained. Blended and packaged for Paris Lash Academy in the UK.
