Considerations: Despite the frequent referencing of an initial flare of acne when starting is tretinoin, there is no scientific evidence to back this up. You should not expect an initial worsening of acne.3-4 Exposure to sunlight should be minimized as you may be more sensitive to its rays. Ask your doctor before using other medication on the skin, especially anything containing sulfur, resorcinol, or salicylic acid, as the combination may be too irritating. Abrasive soaps and cleansers should be used with caution for the same reason. Side effects can include skin irritation, swelling, lightening or darkening of the skin, an increase in acne sores, excessive redness, and crusted or blistered skin.
Clean your face really well using a mild face cleanser and gently pat dry. Let your skin further air dry and don’t put anything else on it. Don’t put anything else on your face like moisturizer, serum, toner, etc. After a half hour, carefully check your cheeks, chin, forehead and nose, with a hand mirror, for any shine. Also, check if your skin feels tight when you smile or make exaggerated facial expressions.
Efforts to better understand the mechanisms of sebum production are underway. The aim of this research is to develop medications that target and interfere with the hormones that are known to increase sebum production (e.g., IGF-1 and alpha-melanocyte-stimulating hormone). Additional sebum-lowering medications being researched include topical antiandrogens and peroxisome proliferator-activated receptor modulators. Another avenue of early-stage research has focused on how to best use laser and light therapy to selectively destroy sebum-producing glands in the skin's hair follicles in order to reduce sebum production and improve acne appearance.
Again, this is another straightforward method but one that is very effective. We use our sense of touch every day of our lives to ascertain the nature of things. Understanding what type of skin you have is also something that your sense of touch can help you with. Oily complexions will leave visible residue on your fingertips, while healthy, fresh skin will feel smooth to the touch.
If a pore is open, it’s called a blackhead or “open comedo”. Because of the opening, contact with the air oxidizes the dead skin cells inside the pore. The air contact turns the melanin inside them darker in color, similar to the way a peeled banana left exposed to the air will darken. This is how the blackhead forms. The color of a blackhead is not because of dirt. It’s a mixture of air and the skin pigment called melanin.

Genetics play a big part in who gets acne and how severely, but each blemish can be blamed on some combination of sebum production, a bacteria called Propionibacterium acnes (P. acnes), plugged follicles, and inflammation. Finding a good treatment is really about finding the right combination of ingredients to troubleshoot each of those issues. Some factors that might worsen acne include hormones, certain medications, diet and stress.
