Hypo-pigmentation is characterized by the light spots that result from a lack of melanin. With this type of skin damage, melanocytes are depleted from the injured area or lose their ability to produce melanin. This occurs when healthy skin has been replaced with scar tissue. Because scar tissue has a light pink color, it’s more noticeable on people with darker skin tones.
When answering the question "why does stress cause acne?", it is important to note that stress is not the definitive catalyst for breakouts, but rather a factor that worsens a previously existing condition. When stress levels are consistently heightened, adrenal glands signal the production of the male hormone androgen, which signals sebaceous oil glands to secrete more sebum. As this excess oil builds up, acne is more likely to develop. As women produce a larger percentage of androgens in the adrenal gland than men, stress more commonly has an affectation on acne frequency in women.
Comedo (whiteheads or blackheads) or papules. The comedo is the basic acne lesion, which is a plugged pore. If the plugged pore stays under the skin, it's called a closed comedo and forms a white bump or whitehead. Blackheads are comedos that open up and appear blackish on the surface of the skin. This black color is not due to dirt, but because the air reacts with the excess oil.
Sometimes it seems like pimples sprout up overnight, but the process of pimple formation is a bit more complex. So what are the most common causes of pimples? A variety of factors can result in an acne blemish. Pimples can develop on anyone at any age, but tend to be most common amongst teens. Why do teenagers get the brunt of breakouts? Hormone fluctuations. When hormone levels increase, the sebaceous glands found within the skin’s hair follicles produce an excess of sebum. Sebum is a waxy substance that the body produce to keep the skin soft and moisturized. However, when hormonal changes cause an increase in sebum production, the pores can become clogged. This sticky substance can collect dead skin cells, debris, and bacteria, forming a plug in the follicle. Blackheads, whiteheads, pimples, and pustules all begin the same way. Preventing pimples means discovering the reasons you’re breaking out and doing all you can to combat these factors. There is no single answer to the age old question of how to get rid of pimples.
Dermarolling: Those little needle rollers you've been seeing all over social media? Turns out, they're good for more than just a cute Instagram video. "Microneedling works by creating a small 'injury' to the skin, which in turn can increase collagen and elastin production, improving scars and fine wrinkles and reducing hyperpigmentation," explains dermatologist and founder of Curology, David Lortscher, MD. Use the microneedler a few times a week as a part of your nighttime routine after cleansing and before toning. "It’s particularly important to pay attention to sterility, and remember that overdoing can damage the skin and incite inflammation, so proceed with caution if you are considering home treatments. Consider a consultation with a dermatologist to explore in-office options," says Dr. Lortscher.
Drugs: Some medications may cause or worsen acne, such as those containing iodides, bromides, or oral or injected steroids (either the medically prescribed prednisone [Deltasone, Orasone, Prednicen-M, Liquid Pred] or the steroids that bodybuilders or athletes sometimes take). Other drugs that can cause or aggravate acne are anticonvulsant medications and lithium (Eskalith, Lithobid). Most cases of acne, however, are not drug related.
