Instead of trying to figure out what was in the sunscreen you used, try to go through all of the foods and drinks you consumed the day before you got your first acne, and the same day you got acne.

Acne come from inside. If it was just your sunscreen, Acne would be gone once you stop using it.
99% of people suffering from acne, have problem with liver, diet and digestion.
The problem could be on many levels, but liver is almost always overworked organ, affecting the rest of the digestion, colon, candida fungi, leaky gut, microbiota.
