DIY Sunscreen Hack - Or Fail?

Описание: ☀️ Busting Sunscreen Myths  
 
Don’t let misinformation get in the way of sun protection and healthy skin this summer!  
 
I do appreciate that this beauty creator is recommending sunscreen. Unfortunately, this DIY (and any sunscreen DIY really) is not recommended as it involves mixing sunscreen into other products. 
 
Sunscreens not only need to be applied at a dosage of 2 mg per cm2 to get the protection advertised on the bottle but need to form a continuous film on the skin. This is what ensures not only even coverage but that your sunscreen remains in place until it’s time to reapply. 
 
Sunscreen tips this summer: 
store bottle in cool, dark place 
always keep in original packaging 
apply liberally and often 
apply 1/4 tsp for face, neck, and ears 
apply a little less than 1 shot glass for the body (35 mL, about 7 teaspoons) 
wait 15 minutes after applying sunscreen to get dressed, apply makeup, etc
 
I hope this helps and my main message this summer is to be be critical of the content you consume - and whether the person sharing it has the necessary knowledge.
