What is a pimple in the first place? A pimple is a small comedone, pustule or papule that forms a skin lesion; the more technical term is acne vulgaris. There are numerous causes, but regardless of the cause, pimples develop when the sebaceous glands (oil glands) get clogged and infected from bacteria. This is why pimples swell up and become red, pus-filled lesions on the surface, and just under the surface, of the skin. (2)
Baby acne generally lasts longer with breast-fed babies, since the same residual, oil-triggering hormones that the baby was exposed to in the uterus can come through the mother's milk, too. As a result, it often begins clearing up as your baby is weened off of breast-milk. It may even clear up sooner if your baby's oil glands have matured enough to handle the hormones before then.
The main hormonal driver of oily sebum production in the skin is dihydrotestosterone.[1] Another androgenic hormone responsible for increased sebaceous gland activity is DHEA-S. Higher amounts of DHEA-S are secreted during adrenarche (a stage of puberty), and this leads to an increase in sebum production. In a sebum-rich skin environment, the naturally occurring and largely commensal skin bacterium C. acnes readily grows and can cause inflammation within and around the follicle due to activation of the innate immune system.[10] C. acnes triggers skin inflammation in acne by increasing the production of several pro-inflammatory chemical signals (such as IL-1α, IL-8, TNF-α, and LTB4); IL-1α is known to be essential to comedo formation.[45]

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.

A nodule is an abnormal tissue growth which can either develop just below the skin or anywhere within the skin’s three layers (the epidermis, dermis, and subcutaneous tissue). Nodules commonly form in regions such as the face, neck, armpits, and groin, although they can also develop on internal organs such as the lungs, thyroid, and lymph nodes. They create solid, raised lumps that are more than 1 to 2 centimeters in diameter, with the potential to reach up to the size of a hazelnut. Nodules are hard and firm to the touch, unlike cysts whose pus makes them softer to the touch. This type of severe acne should be consulted by a doctor, as it might be indicative of a more serious condition.
Antibiotics. These work by killing excess skin bacteria and reducing redness. For the first few months of treatment, you may use both a retinoid and an antibiotic, with the antibiotic applied in the morning and the retinoid in the evening. The antibiotics are often combined with benzoyl peroxide to reduce the likelihood of developing antibiotic resistance. Examples include clindamycin with benzoyl peroxide (Benzaclin, Duac, Acanya) and erythromycin with benzoyl peroxide (Benzamycin). Topical antibiotics alone aren't recommended.

Therefore, it is very important that you wear sunscreen everyday, with an SPF of 30.Of note, after SPF 30, there are decreasing marginal returns in UVB protection. The % of UVB protection as a function of SPF Value is a log graph and plateaus after SPF 30. Therefore, there is not much difference in protection between SPF 40 and 50. Sunscreens with an SPF 100 are banned in some countries.
Baby acne almost always goes away on its own with no intervention. But bring it to your pediatrician's attention if the bumps look like they might be infected (for example, skin appears extra red, you notice swelling or discharge, or your child spikes a fever or has other symptoms) or if you suspect an allergic reaction or eczema (which may require a cream to keep the rash from spreading).

Sometimes birth control alone isn’t enough to really make a difference in hormonal acne. That’s when your doctor might recommend adding in an androgen blocker such as Spironalactone. Spiro (as it’s called) minimizes the amount of androgen hormones in circulation by blocking the receptors that bind with testosterone. When these pills are taken at the same time as an oral contraceptive, 90 percent of women see an improvement in breakouts, according to Linkner. The drug is sometimes prescribed to women with PCOS (polycystic ovarian syndrome) to relieve androgen-related symptoms like excessive hair growth, hypertension, oily skin, and acne.

Isotretinoin (previously known as Accutane) is the most effective form of acne therapy and the only one that can actually result in a cure for your acne. After finishing a course 80 percent of people never see acne again. It works so well because it unclogs pores, kills bacteria, reduces oil production and reduces inflammation. It's taken as a daily pill. Isotretinoin has numerous rare and potential side effects that has made it a controversial choice, but for patients with severe acne there is often no other option. Patients taking isotretinoin must also be on highly effective birth control as the drug can cause birth defects. Isotretinoin can only be taken under close medical supervision.
1. Topical Treatment: This refers to acne medications which are applied directly onto the skin, such as creams, gels, serums and ointments. Topical treatments can be found over-the-counter (OTC) or at a pharmacy when prescribed by a doctor. If you’re shopping for topical treatment solutions, look for products that contain acne-fighting ingredients such as salicylic acid, benzoyl peroxide, and glycolic acid that can penetrate pores to loosen and dissolve debris. Topical solutions are generally best suited to treat mild to moderate acne. 2. Systematic Treatment: Systemic acne medications are consumed orally, such as antibiotics or hormone pills, and work from the inside out to help clear your complexion. Antibiotics can help kill the bacteria lodged within infected pores to reduce inflammation, redness and swelling. Hormones pills such as birth control are frequently used to regulate androgen levels and treat hormonal acne. You won’t be able to purchase systemic treatments OTC and will need a doctor’s recommendation for these medications.

How to Handle It: Consider salicylic acid your secret weapon. "This beta hydroxy acid helps remove excess oil and exfoliate dead cells from the skin's surface to keep pores clear," says Zeichner. Try Clinique's Acne Solution Clearing Gel, a two-time Best of Beauty winner that packs both salicylic acid and sea whip extract — an ingredient with skin-soothing properties — to help counteract the dryness sometimes caused by salicylic acid. The formula does double duty: It works as a spot treatment for mild to moderate acne and as a nightly allover treatment for pimple prevention. And since it dries clear, you can wear it to fight zits whenever, wherever.

Flutamide, a pure antagonist of the androgen receptor, is effective in the treatment of acne in women.[101][108] It has generally been found to reduce symptoms of acne by 80 or 90% even at low doses, with several studies showing complete acne clearance.[101][109][110] In one study, flutamide decreased acne scores by 80% within 3 months, whereas spironolactone decreased symptoms by only 40% in the same time period.[110][111][112] In a large long-term study, 97% of women reported satisfaction with the control of their acne with flutamide.[113] Although effective, flutamide has a risk of serious liver toxicity, and cases of death in women taking even low doses of the medication to treat androgen-dependent skin and hair conditions have occurred.[114] As such, the use of flutamide for acne has become increasingly limited,[113][115][116] and it has been argued that continued use of flutamide for such purposes is unethical.[114] Bicalutamide, a pure androgen receptor antagonist with the same mechanism as flutamide and with comparable or superior antiandrogenic efficacy but without its risk of liver toxicity, is a potential alternative to flutamide in the treatment of androgen-dependent skin and hair conditions in women.[106][117][118][119]
Acne removal: Your dermatologist may perform a procedure called “drainage and extraction” to remove a large acne cyst. This procedure helps when the cyst does not respond to medicine. It also helps ease the pain and the chance that the cyst will leave a scar. If you absolutely have to get rid of a cyst quickly, your dermatologist may inject the cyst with medicine.
