How it works in skincare

In cosmetics and skincare formulations, a Safety Warning appears on packaging when an ingredient has been assessed by the Scientific Advisory Group on Chemical Safety or under UK REACH and is deemed to need specific usage limits, patch testing advice or avoidance instructions for certain groups. It ensures consumers can make informed choices while complying with the Cosmetic Products Regulation (EC) 1223/2009 as retained in UK law.

Where it comes from
