Acne is a disorder that affects the skin’s oil glands and hair follicles. The small holes in your skin (pores) connect to oil glands under the skin. … The pores connect to the glands by a canal called a follicle. Inside the follicles, oil carries dead skin cells to the surface of the skin.
Stress triggers acne and acne results in more stress, so it’s a very vicious cycle. Basically, when you’re under pressure, your skin produces stress hormones, including cortisol, that can stimulate your oil glands to make testosterone that then increases oil production and clogs pores.
Benzoyl peroxide, also known as BP, or, since the BP oil spill, as BPO, is the active ingredient in the majority of acne products you can buy over the counter or get by prescription. Benzoyl peroxide breaks down into two compounds that both kill bacteria and reduce the sensitivity to the skin to the immune system.
Distinguish between a sebaceous cyst and epidermoid cyst. An epidermoid cyst is more common than a sebaceous cyst. Each will have slightly different symptoms and will be treated just a little differently. Therefore, it is important that the cyst you have on your skin is diagnosed appropriately for effective treatment.
Both types of cysts are flesh-colored or white-yellow and have a smooth surface.
Epidermoid cysts are more common. These are slow growing and often painless. They don’t usually require treatment, unless they are causing pain or become infected.
Pilar cysts are composed primarily of keratin (the protein that makes up hair and nails) and form from the outer hair root sheath, typically on the head. A pilar cyst is often thought to be another term for a sebaceous cysts, but they are in fact different.
Sebaceous cysts are commonly found in the hair follicles on the head. They form inside the glands that secrete sebum, an oily substance that coats the hair. When these normal secretions are trapped, they develop into a pouch containing a cheese-like substance. They are commonly found in areas near the neck, upper back, and on the scalp. Sebaceous cysts are often confused with pilar or epidermoid cysts.
Distinguish between cysts in the breast and tumors. Cysts can be in one or both breasts. Without a mammogram or needle biopsy it is almost impossible to distinguish between the two different types of lumps in the breast. Symptoms of a breast cyst will include:
- Smooth, easily movable lump with distinct edges
- Pain or tenderness over the lump
- Size and tenderness will increase just before your period starts
- Size and tenderness will decrease when your period ends
Understand cystic acne. Acne is a general term that describes a variety of different types of pimples, blackheads, pustules, whiteheads and cysts. Cystic acne are nodules that are red, raised, often 2–4 mm in size and nodular and are the most severe form of acne. The infection in a cystic acne is deeper than that in other pustules or whiteheads. Cystic acne is painful.
