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 happens when oil (sebaceous) glands come to life around puberty, when these glands are stimulated by male hormones that are produced in the adrenal glands of both boys and girls. The oil glands, which are located just beneath the skin, continuously produce and secrete oil through openings in the skin.
