Many people may have experienced acne problems during adolescence.

At teenage, a large amount of DHEA (dehydroepiandrosterone) hormone, which is one of the adrenal male hormones, inclined to be secreted more. This is one of the causes of adolescent pimples. 
However, this DHEA begins to decrease in the 20’s, so these kind of acne will be naturally cleared.

On the other hand, not a few people suffer from “adult acne” in their twenties and thirties.

This is due to the combination of various factors different from acne experienced in teens, and it is particularly seen in women more than men .

Various menstrual issues including PMS and menstrual irregularities, in addition to gynecological diseases, medications, and stress also can increase the secretion of male hormones, cuing in acne.

It is highly possible that the increase of male hormones can cause acne appeared around the mouth and face line before menstruation.

If your skin is prone to acne over period of time, due to your menstrual cycle or busy life style, what you can do first would be to switch to your skincare  for acne, only when it blemishes your skin.

When you feel stressed, it can disturb the hormone balance as well as trigger neurotransmitter called substance P. This may stimulate the sebaceous glands, increasing sebum secretion, resulting inflamed acne.*

If your acne feels like to be associated with emotional problems and tend to break out in a specific place such as the cheek, you should review your lifestyle including sleeping pattern and diet, and find a time to relax yourself.

Also, if your stress is likely to be linked to digestive disorders as well, you can look at diet or supplementation for the intestinal environment. Fermented foods and probiotics can improve both the skin and digestive system. 

When you take carbs such as rice, bread and pasta into the body, they are broken down into sugars, raises blood sugar levels and turns to the energy source. When the blood sugar level rises, insulin is secreted in an attempt to lower it, and excess sugar becomes triglyceride, which becomes accumulated in the body. This can trigger the formulation of acne as a material for sebum can augment.

In your diet, take Vitamins A, C, E and B to improve breakout. Broccoli, tomato, tofu (soybean products), and seaweed are recommended.

Other causes of acne include high humidity and temperature environment, skin irritation of hair care and make-up products, and inheritance etc.
For these cases, review the product you are currently using and your lifestyle and diet.

If you are suffering from “adult acne” for a long period of time, first try changing your skincare for acne, review your diet, sleep, and manage your stress, and in some cases, take supplement to treat from inside. By doing so, you can improve your symptoms sooner.
