Shah often recommends over-the-counter retinols or prescription retinoids to her acne-prone patients. “I find that compared to other treatments they are beneficial for not just treating acne but also preventing new acne from forming as they help prevent that initial stage of the follicle getting clogged,” she says. “They can also help with some of the post acne [problems] such as hyperpigmentation.” But keep in mind if you have sensitive skin (or eczema or rosacea), a prescription retinoid might be too strong an option. However, your dermatologist can recommend an over-the-counter retinol with a low concentration (0.1 to 0.25 percent), which might be better tolerated. Retinol also isn’t a quick fix. It takes time to see results, and it’s something you’ll have to keep using to maintain its benefits. Shah also mentions that retinol plays well with other acne treatments on the list. "Retinol can be combined with other over-the-counter or prescription medications such as benzoyl peroxide, topical antibiotics, and oral medications. The right combination depends on the severity of the acne and your skin type."
The second reason is that alcohol is super at removing oil from the skin. The problem lies in the fact that alcohol removes too much of this oil. This can cause your complexion to become raw and irritated. Also, your glands will react to the sudden lack of oil/sebum by trying to generate more and more. As noted before, this will result in a viscious cycle that will be disastrous for the well-being of your skin.

In terms of their effectiveness, both these ingredients are beneficial. Any related product worth its salt will have either one of these in their formula. In fact, some products incorporate both. However, in saying this, our research has provided conclusive proof that salicylic acid is the one to choose. Below are the main points as to why we think this is the case:


Hypertrophic scars are uncommon, and are characterized by increased collagen content after the abnormal healing response.[31] They are described as firm and raised from the skin.[31][33] Hypertrophic scars remain within the original margins of the wound, whereas keloid scars can form scar tissue outside of these borders.[31] Keloid scars from acne occur more often in men and people with darker skin, and usually occur on the trunk of the body.[31]
Any acne treatment is a weeks-long experiment that you’re conducting with your skin. Acne is slow to heal, and in some cases, it can get worse before it gets better (nearly every benzoyl peroxide product we looked at emphasized the likeliness of irritating acne further, and starting off with a lighter application). April W. Armstrong, a doctor at the University of California Davis Health System, recommends waiting at least one month before you deem a product ineffective.
Dermabrasion is an effective therapeutic procedure for reducing the appearance of superficial atrophic scars of the boxcar and rolling varieties.[31] Ice-pick scars do not respond well to treatment with dermabrasion due to their depth.[31] The procedure is painful and has many potential side effects such as skin sensitivity to sunlight, redness, and decreased pigmentation of the skin.[31] Dermabrasion has fallen out of favor with the introduction of laser resurfacing.[31] Unlike dermabrasion, there is no evidence that microdermabrasion is an effective treatment for acne.[8]
Considerations: Despite the frequent referencing of an initial flare of acne when starting is tretinoin, there is no scientific evidence to back this up. You should not expect an initial worsening of acne.3-4 Exposure to sunlight should be minimized as you may be more sensitive to its rays. Ask your doctor before using other medication on the skin, especially anything containing sulfur, resorcinol, or salicylic acid, as the combination may be too irritating. Abrasive soaps and cleansers should be used with caution for the same reason. Side effects can include skin irritation, swelling, lightening or darkening of the skin, an increase in acne sores, excessive redness, and crusted or blistered skin.
Clascoterone is a topical antiandrogen which has demonstrated effectiveness in the treatment of acne in both males and females and is currently in the late stages of clinical development.[120][121][122][123] It has shown no systemic absorption or associated antiandrogenic side effects.[122][123][124] In a direct head-to-head comparison, clascoterone showed greater effectiveness than topical isotretinoin.[122][123][124] 5α-Reductase inhibitors such as finasteride and dutasteride may be useful for the treatment of acne in both males and females, but have not been thoroughly evaluated for this purpose.[1][125][126][127] In addition, the high risk of birth defects with 5α-reductase inhibitors limits their use in women.[1][126] However, 5α-reductase inhibitors can be combined with birth control pills to prevent pregnancy, and are frequently used to treat excessive hair in women.[125] There is no evidence as of 2010 to support the use of cimetidine or ketoconazole in the treatment of acne.[128]
Combination therapy—using medications of different classes together, each with a different mechanism of action—has been demonstrated to be a more efficacious approach to acne treatment than monotherapy.[10][46] The use of topical benzoyl peroxide and antibiotics together has been shown to be more effective than antibiotics alone.[10] Similarly, using a topical retinoid with an antibiotic clears acne lesions faster than the use of antibiotics alone.[10] Frequently used combinations include the following: antibiotic and benzoyl peroxide, antibiotic and topical retinoid, or topical retinoid and benzoyl peroxide.[46] The pairing of benzoyl peroxide with a retinoid is preferred over the combination of a topical antibiotic with a retinoid since both regimens are effective but benzoyl peroxide does not lead to antibiotic resistance.[10]
The relationship between diet and acne is unclear, as there is no high-quality evidence that establishes any definitive link between them.[51] High-glycemic-load diets have been found to have different degrees of effect on acne severity.[7][52][53] Multiple randomized controlled trials and nonrandomized studies have found a lower-glycemic-load diet to be effective in reducing acne.[52] There is weak observational evidence suggesting that dairy milk consumption is positively associated with a higher frequency and severity of acne.[50][51][52][54][55] Milk contains whey protein and hormones such as bovine IGF-1 and precursors of dihydrotestosterone.[52] These components are hypothesized to promote the effects of insulin and IGF-1 and thereby increase the production of androgen hormones, sebum, and promote the formation of comedones.[52][56] Available evidence does not support a link between eating chocolate or salt and acne severity.[51][54] Chocolate does contain varying amounts of sugar, which can lead to a high glycemic load, and it can be made with or without milk. Few studies have examined the relationship between obesity and acne.[2] Vitamin B12 may trigger skin outbreaks similar to acne (acneiform eruptions), or worsen existing acne, when taken in doses exceeding the recommended daily intake.[57] Eating greasy foods does not increase acne nor make it worse.[58][59] One review linked a Western pattern diet, high in simple carbohydrates, milk and dairy products, and trans fats and saturated fats, along with a low omega-3 fatty acids, with acne.[56]
Decreased levels of retinoic acid in the skin may contribute to comedo formation. To address this deficiency, methods to increase the skin's production of retinoid acid are being explored.[10] A vaccine against inflammatory acne has shown promising results in mice and humans.[49][180] Some have voiced concerns about creating a vaccine designed to neutralize a stable community of normal skin bacteria that is known to protect the skin from colonization by more harmful microorganisms.[181]
