What is acne? • Acne is pimples on the surface of the skin as a result of pores in the skin becoming clogged with sebum.
What causes acne? • Acne is caused by overactive sebaceous glands in the skin and the accumulation of the oil, dead skin cells, and bacteria in the pores.
Acne and Teenagers • When hormones become active during puberty they stimulate the sebaceous glands to produce more oil than usual. This often results in acne for teenagers.
Mild Acne • Most people suffer from mild acne, which includes blackheads and whiteheads.
Moderate Acne • Moderate acne includes papules, red inflammed pimples and pustules, and red pimples with white centers.
Severe Acne • Severe acne is characterized by nodules and painful, pus-filled cysts or lumps under the surface of the skin.
What is the t-zone? • The t-zone includes the forehead, nose and chin. • People are very prone to pimples in this area because it contains many oil-producing glands.

Over Washing • Sometimes we are tempted to wash our faces several times a day when we have acne. • If you over-wash your face you can further damage or irritate your acne by drying out your skin.
Make-up and Acne • You can still use make-up during acne breakouts as long as the make-up is non comedogenic . • Some make-ups and concealers contain acne fighting products like benzoyl peroxide and salicylic acid.

Acne on the Body • We can also develop acne on other body parts such as our backs and chest. • Avoid tight clothing in these areas because it can rub the skin and cause irritation which can make acne worse.
Non Comedogenic Skin Products • Non comedogenic skin products are things such as lotions, creams and make-up that will not clog pores.
Tips to help prevent breakouts • Wash face twice per day with warm water and soap. • Don’t pop pimples. • Avoid touching your face with your fingers. • Clean sunglasses and glasses frequently. • Avoid tight clothing to prevent acne on the body. • Remove all make-up before bedtime. • Keep hair clean and out of your face. • Protect your skin from the sun.
Why is it not a good idea to pop pimples? • It is not a good idea to pop pimples because you can push infected materials deeper into the skin which can lead to more swelling, redness and perhaps scarring.
What is the link between popping pimples and acne scarring? • Popping pimples pushes the contents of the pimple deeper into the skin which causes more swelling and redness. • This can cause permanent red and brown marks to form.
Laser Resurfacing • A doctor or dermatologist can perform laser surgery to help heal acne scars. • The laser will remove the top layer of skin and tightens the middle layer. • This process will smooth the surface of the skin.
Dermabrasion • Dermabrasion is a method used to treat acne scarring. • A rotating wire brush or spinning diamond instrument is used to wear down the surface of the skin.
Fractional Laser Therapy • Fractional laser therapy works at a deeper level than both dermabrasion and laser resurfacing. • It doesn’t wound the top layer of skin so time to heal is shorter.
Don’t Do It! • Doctor’s do not recommend that you load up your face with fancy creams of lotions that will only irritate your skin further.
Eczema • Eczema is a skin condition that cause skin to become red, itchy, and dry. • You can recognize eczema by the dry red patches that often form where your skin bends like on your elbows, knees, face and neck.
