Lavender induces tranquility too, but it can also cause enough skin irritation that in May 2014 the Swedish Chemicals Agency (SCA) proposed a health warning on lavender products. The European Union is now considering labeling lavender, “May Be Harmful if Inhaled.” More specifically, a lavender allergy is caused by a compound within lavender extract called linalool. Linalool produces lavender’s fragrance and reacts with air to form the skin irritant. The natural extract of a lavender plant contains 20 to 40 percent linalool, depending on the plant variety, and chemists can synthesize linalool at a purity of 97 percent.

Acne myths
Despite being one of the most widespread skin conditions, acne is also one of the most poorly understood. There are many myths and misconceptions about it:

'Acne is caused by having dirty skin and poor hygiene'
Most of the biological reactions that trigger acne occur beneath the skin, not on the surface, so the cleanliness of your skin has no effect on your acne. Washing your face more than twice a day could just aggravate your skin.
