Keto Diet’s Effects on Skin Health and Complexion

The ketogenic (keto) diet has gained immense popularity in recent years, primarily for its potential weight loss benefits. However, many people are also curious about how this high-fat, low-carb diet may impact their skin health and complexion. In this article, we’ll explore the various ways the keto diet can affect your skin, both positively and negatively, and provide specific answers and solutions to common concerns.

Understanding the Keto Diet

Before diving into the effects of the keto diet on skin health, it’s essential to understand the basics of this eating plan. The keto diet involves consuming a high amount of fats, a moderate amount of proteins, and a very low amount of carbohydrates. This macronutrient distribution encourages the body to enter a state called ketosis, where it burns fat for energy instead of carbohydrates.

Positive Effects of the Keto Diet on Skin Health

There are several ways the keto diet can positively impact your skin health and complexion. Some of these benefits include:

1. Reduced Inflammation

One of the primary benefits of the keto diet is its potential to reduce inflammation in the body. Inflammation is a significant contributor to various skin issues, including acne, eczema, and psoriasis. By following a keto diet, you may experience a decrease in inflammation, leading to improved skin health and a clearer complexion.

A study published in the Journal of Investigative Dermatology found that a high-fat, low-carb diet could reduce inflammation and improve skin health in mice. While more research is needed to confirm these findings in humans, the results are promising.

2. Balanced Hormones

Hormonal imbalances can contribute to various skin issues, including acne and premature aging. The keto diet may help balance hormones by stabilizing insulin levels. Insulin is a hormone that regulates blood sugar levels, and high insulin levels can lead to increased sebum production and inflammation, both of which can contribute to acne.

A study published in the Journal of Clinical Endocrinology and Metabolism found that a low-carb diet could help improve hormonal balance in women with polycystic ovary syndrome (PCOS), a condition often associated with hormonal imbalances and acne.

Negative Effects of the Keto Diet on Skin Health

While the keto diet can offer some benefits for skin health, it’s essential to be aware of potential negative effects as well. Some of these include:

1. Keto Rash

One potential side effect of the keto diet is a skin condition called prurigo pigmentosa, commonly known as “keto rash.” This rash typically appears as itchy, red bumps on the skin and is thought to be related to the body’s adjustment to ketosis.

Although the exact cause of keto rash is not well understood, it’s believed to be related to the release of ketones and other byproducts during the fat-burning process. To alleviate keto rash, you may need to increase your carbohydrate intake slightly or consult with a healthcare professional for further guidance.

2. Nutrient Deficiencies

The restrictive nature of the keto diet can sometimes lead to nutrient deficiencies, which can negatively impact skin health. For example, a lack of essential fatty acids, vitamins, and minerals can contribute to dry skin, inflammation, and other skin issues.

To avoid nutrient deficiencies while following a keto diet, it’s crucial to consume a variety of nutrient-dense foods, such as leafy greens, nuts, seeds, and fatty fish. You may also consider taking a high-quality multivitamin to ensure you’re meeting your daily nutrient needs.

3. Dehydration

Dehydration is a common issue for those following a keto diet, as the body tends to lose more water during the initial stages of ketosis. Dehydration can lead to dry, dull skin and exacerbate existing skin issues.

To combat dehydration, make sure to drink plenty of water throughout the day and consider adding electrolytes to your diet, either through food sources or supplements.


The keto diet can have both positive and negative effects on skin health and complexion. While it may help reduce inflammation and balance hormones, it can also cause keto rash, nutrient deficiencies, and dehydration. To maximize the benefits of the keto diet for your skin, it’s essential to be aware of these potential issues and take steps to address them.

In summary, the keto diet can offer some benefits for skin health, but it’s crucial to be mindful of potential drawbacks. By staying well-hydrated, consuming a variety of nutrient-dense foods, and addressing any skin concerns that arise, you can enjoy the benefits of the keto diet while maintaining a healthy, glowing complexion.
