How to get the look: Fairycore-inspired make-up is in, which means sparkles, face gems and glitter.

Don't go for subtle, says Skinner. "The 'no make-up look' is gone. Clean girl is out!"

There's a child-like quality to festival make-up, he says, so embrace it - think playful colour and crystals.

To stand out, he suggests using glitter in hair partings or your shoulders.

"Personally, I say use gems as they're bigger and more impactful, plus you can peel them off at the end of night and reuse them in the morning."

What to be aware of: Skip near the eyes to avoid nasty scratches on your cornea, says the British Skin Foundation's Dr Emma Wedgeworth, and never use craft glitter.

Use biodegradable, eco-friendly products that are better for the environment and softer on the skin. Safe adhesives, like lash glue, will keep it in place.
