Here’s a special event for all the sunscreen nerds! I’ve teamed up with Jen of The Eco Well to organise the Sunscreen E-Summit, which is happening 15 May! This is a FREE event featuring some incredible speakers that you’d normally have to pay expensive conference fees to learn from, including academic researchers, ingredient supplier representatives, sunscreen formulators and regulatory experts. …
