Best holiday Shellac to avoid sunlight damage

[Skinpassion]

Hi everyone all my clients who come back from holiday have faded shellac. Myself I have noticed on holiday my shellac dulls on day one and fades! Any good colours to use that have less of an effect? Or anything we can do to stop the dulling of top coat

Dulling of top coat is product breakdown... Probably down to suntan lotion with insect repellent in it, or the repellent by itself. Most repellents contain Deet which melts gel polish and L&P like acetone.
