TEA TREE OIL Side Effects & Safety. Tea tree oil is POSSIBLY SAFE for most people when put on the skin, but it can cause skin irritation and swelling. In people with acne, it can sometimes cause skin dryness, itching, stinging, burning, and redness.
Baby acne is a very common skin rash which usually develops in the first few weeks after birth. It is more common in boy babies than girl babies. This rash confuses many parents who assume (and not unreasonably) that acne is something which affects adults, especially teenagers.
Acne is a broader term than pimples. Acne refers to the skin disease involving sebum (skin oil), keratinization (shedding dead skin cells), and bacteria. It can range from very mild acne consisting of mostly blackheads, to severe cystic acne. Somewhere in the middle, but leaning towards more severe acne is what most would call pimples.
