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 common during pregnancy. In fact, more than one out of every two pregnant women can expect to develop acne. In some cases, the acne may be severe. The primary cause of acne when you're pregnant is the increased hormone levels in the first trimester. The higher level increases the skin's production of natural oils. It's hard to predict who will develop pregnancy acne.
