If hormone operation is malfunction, the sebaceous glands will secrete more sebum. The outer layers of skin will be quickenly shed. Such remainders will block the path of sebaceous glands and follicles as well. This state will help Proteobacteria Acne which hide in sebaceous glands to grow up and cause acne. Another cause is the irritation and allergy of cosmetics, drugs or some food (but still no research to prove which food cause acne)

Why whitehead Why blackhead

The excess oil and unusual dead skin cells will group into soft white stuff to block follicles. If the top of follicles is blocked by skin cell, it is called Whitehead/Milia. If nothing block the top of follicles, the white stuff will hit the air and change to black color which is called Blackhead. Whitehead and Blackhead will become Papules and Pustules when bacteria grow up in the blocked follicles. The inflamed and excess oil will make the wall of sebaceous glands leak out. The oil and dead skin cells bacteria will dissolve through cell tissue. The immune system will repair skin cell so that it make the inflamed pimple.

How to treat acne?

Do not waste your time to treat only seen acne since the causes are under your skin. Any treatment will not work for example: if you use the product for drying blemishes, not only it canot absorb oil on blemishes but also make skin irritation and caused scar. Therefore, the best way to treat acne is to scrub to reduce the accumation of dead skin cells for both outer layers of skin and follicles.

To kill the bacteria that cause acne, to reduce oil and make hormone balance to control the secretion of sebum: use soluble cleanser and no ingredient of skin irritation such as soab, scrub in order to avoid stimulation of follicles and to reduce skin infection and dry. The cleansers which contain dead skin cells scrub and antibacteria do not quite work because before these agent activate, they are already washed out.

Exfoliating dead skin cells: since acne is caused inside follicles and related to sebum secretion so the product with salicylic acid which can dissolve oil is enable to exfoliate dead skin cells in follicles mildly. Advise to use gel or lotion without viscosity substance because it will not block up the follicles. Scrub or AHA acid will not work because the exfoliating agent cannot deep into follicles.

Kill bacteria: Alcohol and Sulfura are good ingredients to kill bacteria but they also dry the skin and causes itching so we suggest to use the product with Benzoyl peroxide or Tea Tree (2.5%,5% or 10%). Antibody medicine can kill acne bacteria but also kill Probiotics bacteria.

Increase the creation of skin cells: Dermatologist may use Tretinoin, Differin and Azelaic acid substance which help to skin cells to grow up until it can change the shape of follicles to secret oil easily.

The last supporter: If acne is still be even you have already tried many products, you should consult with Dermatologist. There is one of the best medicine to treat acne: Accutane. Accutane is high vitamin A and is used for severe acne. It also help skin smooth and firm. However ; Accutane is the last choice and must be used under doctor advise because this medicine have severe side effect such as defect during pregnancy and mental problem.
