Acne or breakouts on the forehead can be caused by all sorts of issues, but are most directly related to hormones and stress.
When stress levels rise the body produces more stress hormones, which cause over production of oil and thus a higher chance of a breakout. Lifestyle choices like exercising and sweating may help to get circulation and blood flow going.
Dark spots
Hyperpigmentation (dark spots), can be linked to pollution, smoking and sun damage.
Pollution can cause uneven skin tone, dehydration, dryness, dark spots, expedited aging, wrinkles, sagging and a deterioration of collagen. Pollution releases microscopic particles or free radicals that can go deep into the skin and cause damage to otherwise healthy cells.
As the experts at Effortlessskin.com explain: "These spots are the result of UV damage, although they can pop up years after the actual exposure. They never fade on their own and will get darker are a sign you've had a lot of UV exposure and have damaged skin.
"It's important to know skin cancers can develop from benign sunspots, and it can be hard to tell the difference, if you notice any areas that's changed in size, shape or colour should be checked out by your GP or a dermatologist."
Wrinkles and sagging
Overall signs of loss of elasticity, fine lines, wrinkles and sagging may be caused by Glycation.
The Glycation process (sugars from food and alcohol, that break down the collagen fibers in the skin) speeds up the aging process.
Foods that feed Glycation and cause inflammation in the body and the skin are carbohydrates, fried foods, sugar, fatty meats and alcohol.
Chin/jaw breakouts
Chin or jawline breakouts are typically hormonal acne. Try exfoliating more and always clean your cell phone anything that may touch your chin. Clean all makeup brushes as to not spread bacteria.
