5 Reasons why dermatologists and estheticians should study nutrition


The skin is the largest organ in the human body, and it's directly affected by the nutrients that we consume. Just as a healthy diet can promote overall health and wellness, it can also promote healthy skin. Conversely, a poor diet can lead to skin problems such as acne, eczema, and premature ageing. By understanding the role that nutrition plays in skin health, dermatologists can provide more effective treatments and recommendations to their patients.

 Dietary interventions have traditionally been an underappreciated aspect of dermatological therapy. Recent research, however, has found a significant association between diet and some dermatological diseases. Dietary interventions may be recommended as therapy, as in acne. Dietary change may help to prevent skin disease, as in aging of the skin or skin cancer.  J Clin Aesthet Dermatol. 2014 


Some skin conditions, such as acne and eczema, have been linked to dietary factors. For example, research has shown that a diet high in processed foods and sugar can increase the risk of acne, while a diet rich in omega-3 fatty acids may help reduce the severity of eczema. By studying nutrition, dermatologists can gain a better.

People with Acne have found to eat diets with significantly higher Glycaemic load. Acne sufferers on low glycaemic diets had reduced inflammation and reduced severity of acne.

 Several studies have evaluated the significance of the glycemic index of various foods and glycemic load in patients with acne, demonstrating individuals with acne who consume diets with a low glycemic load have reduced acne lesions compared with individuals on high glycemic load diet  American Journal of Clinical Dermatology


Many skin care products contain nutrients that can benefit the skin. Vitamin C, for example, is a popular ingredient in many skin care products because it can help to brighten the skin and reduce the appearance of fine lines and wrinkles. By studying nutrition, dermatologists can better understand the effects of these ingredients and recommend products that are most likely to be effective for their patients.

 The convergence of food and cosmetics in the beauty industry is a major trend in the recent years, gaining an enormous importance on consumer habits including the diet, the nutritional supplement intake and food-based cosmetics   Trends in Food Science & Technology


Many people are interested in using diet and nutrition to improve their skin health. They may turn to dermatologists for advice on which foods to eat (or avoid) in order to achieve healthy, radiant skin. By studying nutrition, dermatologists can provide accurate and evidence-based advice to their patients on how to achieve healthy skin through diet

  The movement among consumers to eat more natural, organic and cleaner foods that help promote better health and wellness is morphing into a new fast-growing trend: the convergence of food and beauty. As a result, two concurrent developments are taking center stage in the consumer-packaged goods industry — edible beauty, functional food and drink products specifically designed for cosmetic purposes, and the use of food ingredients as the sole or primary ingredient in beauty care products.  USA Chamber of Commerce.

Nutrition is an important factor in overall health and wellness. By understanding the role that nutrition plays in skin health, dermatologists can provide more comprehensive care to their patients and help them achieve overall health and wellness. This can include recommending a balanced diet and providing guidance on supplements that may be beneficial for the skin.

 A whole-foods Plant-based diet maximizes the antioxidant potential within our cells by providing essential vitamins, including vitamins A, C, and E. It also helps to eliminate harmful carcinogens and gerontotoxins within our bloodstream and has been shown to lengthen telomeres, which prevents cellular damage.   Diet and Dermatology, 2020
