A stye (hordeolum) is a local, acutely inflamed growth (swelling, lesion) of the eyelid. They can occur at the lid margin or farther up the lid on either the inner (tarsal) side or the outer (skin) side of the lid. A chalazion is the chronic form of a stye, and its cellular makeup is different than that of a stye.Both the meibomian and sebaceous oil glands of the lid can be involved in this process, which begins with a blockage of the normal openings of these glands, leading to the swelling. Typically, there is bacterial contamination.
Perioral dermatitis is an acne-like condition of unknown cause. Some possible causes are the use of topical corticosteroid creams, cosmetic products, oral contraceptives, fluoride and anti-tartar ingredients in dental products, and it tends to occur in those prone to eczema.
Lupus is a disease in which your body's self-protection mechanism (immune system) attacks your own body rather than a foreign invader. The cause of lupus is unknown, and the disease usually takes one of two forms: systemic lupus erythematosus (SLE), which can affect any body organ; and discoid lupus erythematosus (DLE), which is milder and usually affects only the skin. About 5%–10% of patients with discoid lupus erythematosus will progress to systemic lupus.
Folliculitis refers to an infection of the hair follicles, the tiny pouches under the skin that hold the hair. Folliculitis is most common on the parts of the body that experience friction, such as the face, scalp, back, and thighs. The friction caused by clothing, shaving, and substances such as sweat, oils, and cosmetics can block and irritate the follicles, allowing bacteria that normally reside on the skin, such as Staphylococcus, to get into these follicles and cause the infection. Once infected, the follicles look like red pimples with a hair in the middle of them.
Allergic contact dermatitis is a delayed hypersensitivity reaction (the reaction to the allergen occurs 48–72 hours after exposure). The most common allergens causing allergic contact dermatitis often change with time, as certain chemicals come in or out of use in the manufacture of products that come in contact with the skin. Most recently, common causes of allergic contact dermatitis include nickel, chromates, rubber chemicals, and topical antibiotic ointments and creams. Frequent sensitizers in the general population also include fragrance, formaldehyde, lanolin (wool grease found in ointments and cosmetics), and a host of other common environmental chemicals. Nickel is found in jewelry, belt buckles, metal closures on clothing, and some cell phones. Chromates are used in the process of tanning leather for shoes and in cement, so they can affect construction workers who are in contact with cement. Rubber chemicals are found in gloves, balloons, elastic in garments, mouse pads, and swim goggles. Neomycin is common in triple antibiotic first aid ointments such as Neosporin® (and generic versions of Neosporin) as well as other combination preparations with other antibacterials (eg, Polysporin®). It may also be found in eye preparations and eardrops. Bacitracin is a common ingredient in antibiotic ointments and creams and can cause allergic contact dermatitis as well.Common allergen-containing products include cosmetics, soaps, dyes, and jewelry. Poison ivy is a frequent cause and is discussed separately.
Allergic contact dermatitis is an allergy to a substance (the allergen) touching the skin. The reaction occurs 48–72 hours after exposure. Common allergens are nickel, chromates, rubber chemicals, and neomycin (an antibacterial medication).Nickel is found in jewelry, belt buckles, and metal closures on clothing. Chromates are found in shoe leathers. Rubber chemicals are found in gloves, balloons, and elastic in clothes. Neomycin is common in triple-antibiotic first-aid ointments such as Neosporin® (and generic versions of Neosporin) as well as other combination preparations containing other antibacterials and corticosteroids, as well as other topical ointments, creams, and lotions. It may also be found in eye medications, eardrops, and some vaccines. Common allergen-containing products include cosmetics, soaps, dyes, and jewelry. The most frequent triggers are fragrance, nickel, neomycin, formaldehyde, lanolin, and other chemicals that are common in the environment. Poison ivy is a frequent cause and is discussed separately.
Onychoschizia, commonly known as nail splitting but also known as onychoschisis or lamellar dystrophy, is a condition that causes horizontal splits within the nail plate. Nail splitting is often seen together with onychorrhexis – long-wise (longitudinal) splitting or ridging of the nail plate – and these 2 diseases together are called "brittle nail syndrome." Frequent wetting and drying of the hands is the most common cause of nail splitting, so this condition is, therefore, common among house cleaners, nurses, and hairdressers. Nail splitting may also be caused by nail cosmetics (hardeners, polish, polish removers/solvents), nail procedures, and occupational exposure to various chemicals (alkalis, acids, cement, solvents, thioglycolates, salt, sugar solutions). Injury (trauma) may also play a role in the development of brittle nails. Brittle nails may occur due to medical problems, including gland (endocrine system) diseases, tuberculosis, Sjögren syndrome, and malnutrition. People with other skin diseases, such as lichen planus and psoriasis, as well as people taking oral medications made from vitamin A, may also develop nail splitting.
Nail lifting (onycholysis) is the spontaneous separation (detachment) of the fingernail or toenail from the nail bed at the end of the nail (distal) and/or on the sides of the nail (lateral). The appearance of nail lifting may resemble a half-moon, or the free edge of the nail may rise up like a hood. Nail lifting creates space under the nail that gathers dirt and debris made of protein in the nails (keratin). As water accumulates under the nail, bacteria and yeast can also cause the area to become infected.Nail lifting may occur with other skin conditions, such as various forms of eczema (including hand dermatitis), psoriasis, and lichen planus. Nail lifting may also occur with underlying medical problems, including thyroid disease, pregnancy, some forms of infection, and rarely some forms of cancer. Other possible causes are injury to the nails, use of nail cosmetics, and aggressive manicures.Nail lifting may be caused by some medications, such as chemotherapy and drugs made from vitamin A. Some medications (commonly tetracycline) may interact with sunlight to cause nail lifting.
As two aestheticians who have worked in a medical spa for quite some time, we have noticed two distinct trends. First, there are certain treatments that are popular year-round, and second, there are distinct spikes in requests for certain services that correlate with specific seasons. In this post we share our observations with you.
The Food and Drug Administration (FDA) has approved Xeomin for for temporary improvement of moderate to severe glabellar lines (frown lines). Under the brand name Bocouture, Xeomin is already approved in 14 countries including Germany, France, the United Kingdom, Italy and Spain. It was FDA-approved in 2010 for the treatment of cervical dystonia and blepharospasm.
The end of summer is perfect timing for the last topic in my series on Summer Skin Fitness. I started the summer with colorblind laser therapies and then described how you can manage pesky conditions that are made worse by the summer sun. Now summer is nearly over, which makes it the perfect time for treating visible leg veins. In this post I explain 3 different types of visible and bothersome leg veins, treatments that are available, and why this is a good time of year to address them.
CNN reported that the Food and Drug Administration (FDA) has released a warning to consumers that skin creams, beauty and antiseptic soaps and lotions contaminated with mercury have been found in at least 7 states. The products are made aborad and sold within the United States as skin lighteners and anti-aging creams. Products are being promoted as being able to remove age spots, freckles, wrinkles, other skin blemishes and even acne medication for teens.
The FDA has limited oversight when it comes to cosmetics. So what can be done to protect consumers from products that cause adverse affects? Kwa and Xu highlight efforts to regulate a $60 billion industry and explain how you can help.
Cosmetics is a multibillion-dollar-a-year industry with limited regulations. The FDA lacks the power to approve products or an ingredient used in cosmetics and has not specifically determined what is “safe.” Because compounds placed on the skin can readily be absorbed into the body, is this something to be concerned about?
A multitude of over-the-counter skin care products – from sunscreens and moisturizers to cosmetics – tout vitamins and antioxidants as ingredients. What importance do vitamins play in skin and skin health, and do these products really work?
Today’s buzzword in many industries is green, including the personal care and cosmetics business. Words like natural and organic figure prominently on labels and in advertisements. But I’ve discovered it’s hard to get a handle on such terms, even when we are dedicated label readers.
