Intermittent Fasting for Beauty: Does It Work? My Honest Experience

Intermittent fasting (IF) has gained significant attention for its health benefits, but what about its effects on beauty? Can fasting really give you clearer skin, stronger hair, and a radiant glow? I decided to find out for myself and embarked on an intermittent fasting journey. In this article, I’ll share my honest experience with intermittent fasting and explore the science behind its potential beauty benefits.

What is Intermittent Fasting?

Intermittent fasting is not a diet but a pattern of eating that cycles between periods of fasting and eating. Dr. Jason Fung, a nephrologist and author, explains, “Intermittent fasting is a way to give your body a break from constant digestion and allow it to focus on repair and rejuvenation” (Source: The Obesity Code). The most popular methods include:

  • 16/8 Method: Fasting for 16 hours and eating during an 8-hour window.
  • 5:2 Method: Eating normally for five days a week and significantly reducing calorie intake for two non-consecutive days.
  • Eat-Stop-Eat: Fasting for 24 hours once or twice a week.

The Science Behind Intermittent Fasting and Beauty

Reducing Inflammation and Boosting Autophagy

One of the primary ways intermittent fasting may benefit the skin is by reducing inflammation. Cynthia Thurlow, a nurse practitioner and intermittent fasting expert, notes, “Intermittent fasting can have a positive impact on skin health by reducing inflammation, improving insulin sensitivity, and boosting autophagy (cellular repair)” (Source: Everyday Health). Autophagy is the body’s process of cleaning out damaged cells and regenerating new ones, which is crucial for maintaining healthy, youthful skin.

Balancing Hormones

Hormonal balance is essential for clear, healthy skin. Dr. Will Cole, a functional medicine practitioner, explains, “Intermittent fasting can help to balance hormones, which is crucial for clear, healthy skin. It can also help to reduce oxidative stress, which can contribute to premature aging” (Source: Dr. Will Cole).

Promoting Collagen Production

Collagen is a protein that gives skin its structure and elasticity. As we age, collagen production declines, leading to wrinkles and sagging skin. Dr. Rhonda Patrick, a biomedical scientist, points out, “Intermittent fasting can increase the production of human growth hormone (HGH), which is important for cell regeneration and repair, including skin cells” (Source: FoundMyFitness).

Reducing Acne Breakouts

Intermittent fasting may also help to reduce acne breakouts. Dr. Megan Ramos, a dermatologist, states, “Intermittent fasting may help to reduce acne breakouts by lowering insulin levels and reducing inflammation in the body” (Source: Dr. Megan Ramos Dermatology). Lower insulin levels can decrease the production of sebum, the oily substance that can clog pores and lead to acne.

My Intermittent Fasting Journey

Week 1: Getting Started

The first week was all about adjusting to the new eating schedule. I chose the 16/8 method, fasting from 8 PM to 12 PM the next day. Initially, I felt hungry during the fasting period, but I noticed my energy levels were stable throughout the day.

Week 2: Noticing Changes

By the second week, my body had adapted to the new routine. My digestion improved, and I felt less bloated. I also noticed that my skin was starting to look clearer, with fewer breakouts. This change motivated me to continue with the fasting regimen.

Week 4: Seeing Results

After a month of intermittent fasting, the benefits became more noticeable. My skin was brighter and more even-toned, and I had fewer instances of acne. My hair also felt stronger and looked shinier. I attributed these changes to the combination of reduced inflammation, balanced hormones, and improved nutrient absorption.

Personal Anecdote

One memorable moment was when a friend commented on my glowing skin during a casual lunch. She asked me about my skincare routine, and I was thrilled to share my experience with intermittent fasting. It was rewarding to see tangible results from my commitment to this eating pattern.

Practical Tips for Intermittent Fasting

Stay Hydrated

Drinking plenty of water is crucial during fasting periods to stay hydrated and support overall health. Herbal teas and black coffee can also help curb hunger without breaking the fast.

Choose Nutrient-Dense Foods

When it’s time to eat, focus on nutrient-dense foods that provide essential vitamins and minerals for skin and hair health. Incorporate plenty of fruits, vegetables, nuts, seeds, and whole grains into your meals.

Manage Stress

Stress can negatively impact your skin and hair, so it’s important to incorporate stress-reducing practices into your routine. Activities like yoga, meditation, and deep breathing exercises can help manage stress levels.

Be Consistent

Consistency is key to seeing the benefits of intermittent fasting. Stick to your chosen fasting schedule and give your body time to adjust and respond to the changes.

Expert Insights

The Importance of Individualization

Dr. Valter Longo, director of the Longevity Institute at USC, emphasizes the need for personalized approaches: “Intermittent fasting has been shown to have a variety of health benefits, including improved cardiovascular health, reduced inflammation, and increased longevity. These benefits can also translate to healthier, more radiant skin” (Source: USC Longevity Institute). It’s essential to find a fasting schedule that works best for your body and lifestyle.

The Role of Nutrition

Dr. Howard Murad, dermatologist and founder of Murad Skincare, highlights the importance of diet: “The foods you eat can either help or hinder your skin’s natural healing processes. Choose collagen-rich foods to nourish your skin from the inside out” (Source: Murad Skincare). Combining intermittent fasting with a balanced diet can enhance the overall benefits for your skin and hair.

Seeking Professional Advice

Dr. Francesca Fusco, a dermatologist, advises consulting a healthcare professional before starting intermittent fasting: “Intermittent fasting can be a complex issue with various underlying causes. Consulting a dermatologist is crucial for accurate diagnosis and personalized treatment” (Source: Prevention Magazine). This ensures that you are following a safe and effective approach tailored to your specific needs.

Scientific Evidence

Effects of Intermittent Fasting on Skin Health

A study published in Experimental Dermatology investigated the effects of intermittent fasting on skin health in mice and found that it can improve skin barrier function, reduce inflammation, and promote collagen production (Source: Experimental Dermatology). While more research is needed in humans, these findings suggest potential benefits for skin health.

The Effect of Intermittent Fasting on Acne Vulgaris

Another study examined the impact of intermittent fasting on acne severity and found a significant reduction in inflammatory lesions in participants who followed an intermittent fasting regimen (Source: The Journal of Clinical and Aesthetic Dermatology). This highlights the potential of intermittent fasting as a complementary approach to managing acne.

Intermittent Fasting and Skin Aging

A review article in Nutrients discusses the potential benefits of intermittent fasting for skin aging, including its ability to reduce oxidative stress, promote autophagy, and increase collagen production (Source: Nutrients). These mechanisms can contribute to a more youthful and radiant complexion.


Intermittent fasting has the potential to improve skin and hair health by reducing inflammation, balancing hormones, and promoting cellular repair. My personal experience with intermittent fasting has been overwhelmingly positive, leading to clearer skin, stronger hair, and an overall sense of well-being. By staying hydrated, choosing nutrient-dense foods, managing stress, and being consistent, you can maximize the beauty benefits of intermittent fasting.

As Dr. Jason Fung aptly puts it, “Intermittent fasting is not a diet, but a pattern of eating. It’s a way to give your body a break from constant digestion and allow it to focus on repair and rejuvenation” (Source: The Obesity Code). If you’re considering intermittent fasting, consult with a healthcare professional to ensure it’s the right approach for you. Embrace the journey and enjoy the radiant results from within.
