The self tan shake up

Self tan products are changing and consumers are going to notice.
You should too.

DHA self tan shake up
New EU self tan regulations reduce the maximum level of DHA usage to 10%

If you sell a self tanning product you will likely be aware of a looming change to the limit of dihydroxyacetone (DHA) in self tanning products to a maximum of 10% which is going to affect a large number of products on the market.
