Both salicylic acid and benzoyl acid are commonly found in the top acne treatments for getting rid of mild to severe acne. They work in tandem to getting rid of the dead skin and killing bacteria, which are two of the main contributors to the spread of acne. Salicylic acid breaks up the skin to clear pores from skin, oil and bacteria and benzoyl peroxide kills the bacteria slowly over a 48-hour period.
Alpha-Hydroxy Acids – These are synthetic acids derived from sugary fruits that remove dead skin cells3 while reducing inflammation. The two common types that can be found in over-the-counter acne treatments are glycolic acid and lactic acid. Another benefit of these acids is that they improve the appearance of your acne scars and make your pores look smaller by stimulating the growth of new, healthy skin.
Azelaic acid is a natural acid that is derived from various grains like wheat and barley. It helps reduce acne by preventing skin cell buildup, killing p. acnes bacteria, and reducing inflammation4. This means it can help reduce all kinds of acne, from blackheads to pimples. Blackheads and whiteheads form when dead skin cells combine with sebum, the oil our skin naturally produces and get clogged in a pore. To get rid of this kind of acne, it helps to regulate your skin cell production and exfoliate your skin to remove excess dead skin cells. Azelaic acid is a great way to do both of these things, while also decreasing inflammation and killing bacteria. When the skin is inflamed, it swells slightly, causing the pores to constrict. This traps dead skin cells and sebum inside, leading to blackheads and whiteheads, and if bacteria get trapped as well, then pimples can also form.
Hypertrophic scars are uncommon, and are characterized by increased collagen content after the abnormal healing response. They are described as firm and raised from the skin. Hypertrophic scars remain within the original margins of the wound, whereas keloid scars can form scar tissue outside of these borders. Keloid scars from acne occur more often in men and people with darker skin, and usually occur on the trunk of the body.
Although the late stages of pregnancy are associated with an increase in sebaceous gland activity in the skin, pregnancy has not been reliably associated with worsened acne severity. In general, topically applied medications are considered the first-line approach to acne treatment during pregnancy, as they have little systemic absorption and are therefore unlikely to harm a developing fetus. Highly recommended therapies include topically applied benzoyl peroxide (category C) and azelaic acid (category B). Salicylic acid carries a category C safety rating due to higher systemic absorption (9–25%), and an association between the use of anti-inflammatory medications in the third trimester and adverse effects to the developing fetus including too little amniotic fluid in the uterus and early closure of the babies' ductus arteriosus blood vessel. Prolonged use of salicylic acid over significant areas of the skin or under occlusive dressings is not recommended as these methods increase systemic absorption and the potential for fetal harm. Tretinoin (category C) and adapalene (category C) are very poorly absorbed, but certain studies have suggested teratogenic effects in the first trimester. Due to persistent safety concerns, topical retinoids are not recommended for use during pregnancy. In studies examining the effects of topical retinoids during pregnancy, fetal harm has not been seen in the second and third trimesters. Retinoids contraindicated for use during pregnancy include the topical retinoid tazarotene, and oral retinoids isotretinoin and acitretin (all category X). Spironolactone is relatively contraindicated for use during pregnancy due to its antiandrogen effects. Finasteride is not recommended as it is highly teratogenic.
A complete skin care regimen to control acne usually starts with washing. The ideal face wash creates a soft creamy lather in warm water. It rinses off dirt, excess oil, and makeup, leaving the face ready for the next step in daily skin care, whether that is toner, moisturizer, exfoliant, sunblock, or more makeup. It is fragrance-free, and it does not create a foam, film, or tingly sensation on the face. Any product that foams and suds vigorously, like a detergent, is a strict no-no for acne treatment, especially on dry skin.
If your acne is severe, painful, or refusing to get lost, you may just be beyond what an over-the-counter treatment can do. Not only can a professional set you up with the really powerful stuff, but also Fitz Patrick explains that “working closely with an aesthetician or dermatologist means you can keep tweaking a routine to make it work best for you.”
The predisposition to acne for specific individuals is likely explained by a genetic component, a theory which is supported by studies examining the rates of acne among twins and first-degree relatives. Severe acne may be associated with XYY syndrome. Acne susceptibility is likely due to the influence of multiple genes, as the disease does not follow a classic (Mendelian) inheritance pattern. Multiple gene candidates have been proposed including certain variations in tumor necrosis factor-alpha (TNF-alpha), IL-1 alpha, and CYP1A1 genes, among others. Increased risk is associated with the 308 G/A single nucleotide polymorphism variation in the gene for TNF.
If you have dark brown spots where acne has healed, you absolutely, positively have to avoid any of the irritant ingredients listed above. Your product has to be gentle enough not to cause irritation and strong enough to remove makeup. If you are on a budget, then Black Opal Skin Perfecting Blemish Wash, Burt’s Bees Natural Acne Solutions Purifying Gel Cleanser, or Neutrogena Oil-Free Acne Wash will work well. ProActiv Renewing Cleanser or PanOxy soap cost a little more but help heal pimples.
Pimples are raised red spots with a white center that develop when blocked hair follicles become inflamed or infected with bacteria. Blockages and inflammation that develop deep inside hair follicles produce cystlike lumps beneath the surface of your skin. Other pores in your skin, which are the openings of the sweat glands, aren't usually involved in acne.
A major mechanism of acne-related skin inflammation is mediated by P. acnes's ability to bind and activate a class of immune system receptors known as toll-like receptors (TLRs), especially TLR2 and TLR4. Activation of TLR2 and TLR4 by P. acnes leads to increased secretion of IL-1α, IL-8, and TNF-α. Release of these inflammatory signals attracts various immune cells to the hair follicle including neutrophils, macrophages, and Th1 cells. IL-1α stimulates increased skin cell activity and reproduction, which in turn fuels comedo development. Furthermore, sebaceous gland cells produce more antimicrobial peptides, such as HBD1 and HBD2, in response to binding of TLR2 and TLR4.
