For decades, we have told patients that there were no studies to support that drinking soda made acne worse, although if that was their experience then they should not consume soda. Over the recent years, more and more evidence has emerged showing that diet can affect acne. The first study showed that drinking non-organic milk may exacerbate acne. Recently a study published in the The Journal of Academic Nurtition (J Acad Nutr Diet. 2017 Jun 9. doi: 10.1016/j.jand.2017.03.024 ) showed that consuming high-glycemic index carbohydrates is correlated with worsening of acne.
In short, the recommendations have not changed–for all persons, eating a good healthy diet is recommended. What has changed is the evidence showing that poor eating habits is connected with worsening of acne. For all of my patients, acne or not, I recommend avoiding white rice, white potatoes, white flour, and sugar in their diet. Unfortunately, most of my patients, with or without acne, consume a large amount of these high-glycemic index foods, which contributes to obesity, fatigue, and the development of type II diabetes.
One of the most effective topcal acne treatments has been retinoids–Retin A, Differin, & Tazorac. Well now, Differin has been approved for OTC use–no prescription needed. That’s right. Anyone will soon be able to get this medication. This medication combined with OTC Benzoyl Peroxide gel is a 1-2 punch for acne.
Differin works great with our RSB SkinCare Acne kit.
Without question, the single most effective product for acne that is available without a prescription is benzoyl peroxide. All work equally as well for the face–2.5%, 5%, or 10%. Stronger does not mean better, just more drying.
For the face, the gel works great. There are alcohol-based gels for oily skin, and water-based gels–for more dry skin.
These products will bleach hair, clothing, washcloths, towels, and sheets. Therefore, I recommend using them in the MORNING and at dinner time, but wash face before bedtime.
It takes a MINIMUM of 6 weeks to see ANY improvement, so be patient! by 12 weeks, most patients will see 50% improvement. DO NOT spot treat, but treat the entire face. This product works well for pustules and red bumps, but not as well for clogged pores, such as blackheads.
A study published in the Journal of the American Academy of Dermatology evaluated 10 male patients ages 18 to 35. This study showed that the more cocoa ingested, the more the participants’ acne flared.
