Keto And Acne: Is There A Link?

The ketogenic diet is a high-fat, low-carb diet that encourages the body to enter a metabolic state called ketosis, in which fats are converted into ketones, which become the body's primary source of energy. While some people claim that the keto diet can help with weight loss, it also has several nasty side effects, including breakouts. The keto diet can be particularly stressful on the body, throwing many bodily functions out of balance and causing inflammation, which has been linked to skin conditions like acne.

However, the link between the keto diet and acne is complex and not yet fully understood. While some people experience acne breakouts while on the keto diet, others find that their skin clears up completely. Some researchers suggest that this may be because the keto diet reduces insulin levels and related hormones, which play a role in acne formation. Others point to the potential benefits of ketogenic diets in reducing inflammation and lowering insulin-like growth factor 1 (IGF-1) levels, both of which can contribute to acne.

Additionally, the quality of the keto diet may also play a role, with some suggesting that a nutritional keto diet that includes other healthy food items may improve acne by reducing inflammation. On the other hand, an excess of keto diet may cause skin breakouts by increasing the secretion of sebum, which is a food source for the acne-causing bacteria P. Acnes.

High-calorie diets and keto acne

While the keto diet may be great for your waistline, it can have some nasty side effects on your skin. One of the most common reasons for keto acne is a high-calorie diet.

When you reduce your calorie intake, your skin starts making less sebum, which is a key cause of acne. However, on the keto diet, it is common to start eating more calories than before, which can lead to acne breakouts and pimples. This is because high-calorie diets open a pathway in your body called mTORC-1, which senses how much energy you are giving your body. When you give your body a lot of energy in the form of calories, mTORC-1 opens and your body goes into hypermode, stimulating the growth and repair of various things, including skin cells. This overgrowth of skin cells inside your pores, known as hyperkeratosis, can clog your pores and lead to acne.

A 2015 study found that high-fat diets, such as the keto diet, increase the production of sebum on the skin, which can increase your risk of acne. Additionally, a 2007 study showed that higher-fat diets were associated with higher levels of a specific marker for inflammation, known as the C-reactive protein. This suggests that high-fat diets may increase inflammation in the body, which has been linked to skin conditions like acne.

To avoid skin problems while on the keto diet, it is recommended to increase your water intake, as the diet can dehydrate your skin. It is also suggested to limit lactose, as milk and whey-based proteins have been linked to an increase in acne. Using an acne face wash containing salicylic acid or benzoyl peroxide can help remove excess oil and kill acne-causing bacteria. Finally, consider using hydrating products that contain hyaluronic acid, which can help plump up tired, dull-looking skin.

High leucine content and keto acne

High leucine content in the diet is a contributing factor to acne. Leucine is an amino acid found in meat and dairy proteins. It is a major component of whey protein, which is often consumed by people on the keto diet. Leucine activates mTORC1, a nutrient-sensitive kinase that plays a role in acne pathogenesis.

Leucine activates mTORC1 by translocating inactive mTORC1 to Rheb-enriched membrane compartments. mTORC1 is a key regulator of anabolism and lipogenesis. It stimulates the expression of PPARγ and SREBP-1c, promoting sebum production.

High-protein diets, specifically diets high in leucine, also activate and open the body's mTORC1 pathway. This leads to increased production of unbalanced sebum and skin cells, which can clog pores and cause acne.

To reduce acne, it is recommended to limit meat consumption and opt for a more plant-based diet. Vegan keto is a viable option, as it proves that a ketogenic diet can be achieved without a high intake of meat.

Ketogenic diets and skin inflammation

The ketogenic diet is a high-fat, low-carb diet that encourages the body to enter a metabolic state called ketosis, where fats are broken down into ketones, which become the body's primary source of energy instead of carbohydrates or protein. While this dietary shift can have immediate effects on overall health, it can also impact skin health.

The Benefits of Ketogenic Diets for Skin Inflammation

The ketogenic diet can help reduce skin inflammation and improve acne-prone skin in several ways:

• Lower Insulin Levels: Ketogenic diets decrease insulin levels, which can reduce the production of skin cells, sebum, and androgens, creating an environment less conducive to acne breakouts.
• Anti-Inflammatory Effects: Very low-carb and ketogenic diets have been shown to reduce inflammation in the body, which is a key driver of acne progression.
• Decrease in IGF-1 (Insulin-like Growth Factor 1): Restricting carbohydrates helps keep IGF-1 levels low, which can regulate sebum production and prevent clogged pores.

Potential Drawbacks of Ketogenic Diets for Skin Inflammation

However, it's important to note that the ketogenic diet may not be universally beneficial for skin health. In some cases, it can even exacerbate skin issues:

• High-Calorie Intake: The ketogenic diet often involves a high-calorie intake, which can lead to an increase in skin inflammation and acne.
• High Leucine Content: A ketogenic diet high in protein, especially the amino acid leucine, can activate the mTORC-1 pathway, leading to increased sebum production and skin cell growth, resulting in clogged pores and acne.
• Acidic Urine: Ketogenic diets can increase the acidity of urine, causing the body to reabsorb certain compounds it intended to eliminate. This can increase inflammation and worsen acne.
• Dehydration: The ketogenic diet can lead to water weight loss, causing skin cells to shrink and resulting in dry, irritated skin.
• High-Fat Intake: High-fat diets have been linked to increased sebum production and inflammation, which are risk factors for acne and other skin conditions like psoriasis and eczema.

Optimizing Skin Health on a Ketogenic Diet

To mitigate potential skin issues while on a ketogenic diet, consider the following:

• Ensure adequate water intake to counteract dehydration and keep skin cells hydrated.
• Limit lactose and dairy consumption, as these have been linked to increased acne.
• Use acne-specific cleansers containing salicylic acid or benzoyl peroxide to manage breakouts.
• Incorporate hydrating skincare products, such as hyaluronic acid, to plump and moisturize the skin.
• Exfoliate regularly to remove excess dirt, oils, and grime that can contribute to skin inflammation.
• Consult a dermatologist if skin issues persist, as they may recommend products containing retinoids to help shrink pores and minimize sebum production.
• Consider incorporating more whole foods, vegetables, and fatty fish into your diet, as these can promote skin health and reduce inflammation.

Ketogenic diets and skin dehydration

The ketogenic diet is a high-fat, low-carb diet that encourages the body to enter a metabolic state called ketosis, where fats are converted into ketones. While this diet has become increasingly popular for weight loss, it has also been associated with a range of side effects, including skin issues such as acne.

The keto diet can impact the skin in several ways, and the results vary from person to person. Some people report clearer and brighter complexions while following a keto diet, while others experience a strange, itchy red rash known as "keto rash" or prurigo pigmentosa. This rash often appears during the early stages of ketosis.

One of the critical mechanisms by which keto may affect the skin is through its impact on blood sugar levels. By eliminating simple carbohydrates, keto diets help stabilise blood sugar, reducing the release of insulin and insulin-like growth factor-1 (IGF-1). These hormones are linked to acne development.

Additionally, keto diets have anti-inflammatory properties, which can benefit skin conditions. A 2015 study found that high-fat diets increased the production of sebum on the skin, which can contribute to acne. However, it's important to note that not all fats are equal in this regard; omega-3 fatty acids, for example, are known to be beneficial for the skin.

Dehydration and Skin Health on Keto

One specific skin concern that may arise on a keto diet is dehydration. Ross C. Radusky, MD, a dermatologist at SoHo Skin & Laser Dermatology, P.C., explains that the ketogenic diet helps shed water weight, which can lead to a reduction in the size of skin cells. As a result, you may experience dry and irritated skin.

To counter this, Dr. Radusky recommends increasing water intake to ensure skin cells remain adequately hydrated. He also suggests using a 2% hyaluronic acid primer after cleansing and before moisturising, as hyaluronic acid can absorb a significant amount of water, helping to plump and hydrate the skin.

Other Tips for Skin Health on Keto

• Limit lactose, as milk and whey-based proteins have been linked to an increase in acne.
• Use an acne face wash containing salicylic acid or benzoyl peroxide to remove excess oil and exfoliate dead cells that block pores.
• Incorporate hydrating skincare products to naturally plump up tired, dull-looking skin.
• Exfoliate a few times a week to clear excess dirt, oils, and grime from the skin.
• If acne persists, consult a dermatologist, who may recommend products containing retinoids to help shrink pores and minimise sebum production.

While the ketogenic diet has the potential to improve skin health and clear acne for some individuals, it can also cause skin issues for others. Skin dehydration is one such concern, and by increasing water intake and using the right skincare products, it is possible to mitigate the effects of dehydration. However, it is always recommended to consult a dermatologist before making significant dietary changes to ensure they align with your specific skin and health needs.

Ketogenic diets and skin rashes

The ketogenic diet is a high-fat, low-carb diet that encourages the body to enter a metabolic state called ketosis, in which fats are converted into ketones, which become the body's primary source of energy instead of carbohydrates or protein. While this diet can have immediate effects on overall health, it also has some particular impacts on the skin.

In some cases, a well-formulated ketogenic diet has helped individuals reduce skin conditions like acne, but in others, it has elevated problems like rosacea and even skin rashes. The keto diet can cause the secretion of sebum in excess, which is food for the bacteria type P. Acnes that live in the hair follicles and outer skin layer. As these bacteria feed on sebum, their concentration dramatically increases, causing skin breakouts or acne.

The keto diet promotes the production of ketones in the body, which is loosely related to causing skin conditions like acne, rosacea (facial redness), and even skin rashes. However, the diet delivers the desired results when balanced with other nutritious food items.

How to Avoid Skin Problems on a Ketogenic Diet:

• Since the keto diet can suck moisture out of your skin, it is recommended to increase water intake.
• Limit lactose as studies have linked milk and whey-based proteins to an increase in acne.
• Use an acne face wash with salicylic acid or benzoyl peroxide. Salicylic acid helps remove excess oil, and benzoyl peroxide kills acne-causing bacteria.
• Use hydrating products that help naturally plump up tired, dull-looking skin.
• Exfoliate a few times a week to clear your face of excess dirt, oils, and grime.
• See a dermatologist if you are experiencing an acne breakout that you can't get under control. They may recommend products containing retinoids, which can help shrink pores and minimize sebum production.
• Consider ditching the diet as the Mediterranean diet, which is loaded with fatty fish, colorful fruits, and green leafy vegetables, is often considered the best diet for skin health.

Other Tips for Improving Skin Health:

• Consume fatty fish a couple of times a week as it contains anti-inflammatory omega-3 fatty acids, which may improve skin health.
• Eat low-carb vegetables with every meal as they may help promote hormonal regulation and improve skin health.
• Drink green tea, which contains the antioxidant EGCG, known to reduce acne lesions.
• Limit dark chocolate consumption as it may worsen breakouts, especially in acne-prone men.
• Eat mostly whole, minimally-processed foods as processed meats often contain sugar and other additives that can raise insulin levels and cause inflammation.
• Limit alcohol intake as it impairs hormonal balance, impacts sebum production, and increases the likelihood of acne eruptions.
• Exercise daily as it increases insulin sensitivity and reduces the severity of acne.
• Experiment with intermittent fasting, which can help decrease insulin and IGF-1 levels.
