Blemishes
“Blemish” is a broad term that refers to any type of skin mark. There are numerous types of blemishes. Can be red, white, brown, black or grey in colour.
Scarring of the skin occurs when the dermis layer becomes damaged. The dermis is the deep layer of skin where small blood vessels (capillaries), sweat glands, hair follicles, and nerve endings are located. Anything that causes the skin to open can lead to scarring, such as a wound or popped pimples. An overproduction of melanin can cause uneven skin tone or dark patches.
The causes of hyperpigmentation include:
sun exposure
acne scarring
hormonal changes, such as during pregnancy
Infections
Certain types of skin infections can cause blemishes to erupt on the skin. These include Malassezia folliculitis (fungal acne), an infection in the hair follicles. This condition is caused by an overgrowth of yeast and causes pustules to form.
Acne may have a genetic link. Certain hereditary conditions can also cause blemishes to occur.
Sun exposure
Overexposure to the sun’s harmful ultraviolet (UV) A and B rays can cause skin cancer,
hyperpigmentation, and other forms of skin damage.
Clogged pores
An overproduction of oil by the sebaceous glands can cause blemishes. Hormonal changes often trigger this overproduction, such as puberty. Excess oil can mingle with dead skin cells, dirt, or bacteria. This results in pimples, pustules, blackheads, and whiteheads to form.
Pores can become clogged from products, such as makeup, sunscreen, or moisturizers. Look for products labeled as noncomedogenic. These are designed to not clog pores.
Hairstyling products can also clog pores if they get onto your face.
Environmental toxins, such as dirt, car exhaust, and pollution, can sit on your skin, mingle with oil, and clog pores. You can also transfer dirt and bacteria onto your face by touching your face with your hands.
Diet
What you eat might have an impact on your skin. Food allergies and contact dermatitis can both cause skin irritation and bumps. Dairy products, such as skim milk, may cause allergies to some people. Diets high in sugar and simple carbohydrates may also lead to blemishes.
Medications
Some prescription and over the counter (OTC) medications may cause acne as a side effect.
Treatments effective are microdermabrasion, hydrabrasion, peels, skin needling, products especially skin lighteners and sunscreen.
