Skin Reabsorption While On Keto: What To Expect

The ketogenic diet is a popular, effective way to lose body fat and has been linked to several health benefits, including clearer skin. However, the high-fat, low-carb diet can also have negative side effects on the skin, including acne and keto rash. So, will skin reabsorb when doing keto? The answer is yes and no. While keto can help clear acne due to its low-carb nature, stabilising blood sugar levels, and reducing insulin and IGF-1 release, it can also cause acne due to high-calorie and high-leucine content, as well as increased acidity in urine. The key to avoiding acne while on keto is to ensure a balanced diet with the right types of fats and a moderate intake of meat and dairy.

The keto diet can reduce wrinkles and fine lines

The keto diet is a high-fat, low-carb diet that has gained traction for its ability to help people lose weight. However, its effects on the skin have also been a topic of interest. While the keto diet has been associated with both positive and negative impacts on the skin, there is evidence to suggest that it can help reduce wrinkles and fine lines.

The keto diet is based on putting your body into a state of ketosis, where it burns fat instead of carbohydrates for energy. This is achieved by drastically reducing carbohydrate intake, typically to around 5% of one's diet, while increasing fat consumption to roughly 70-80%.

• Lowering blood sugar levels: The keto diet's restriction of carbohydrates and refined sugars helps to lower blood sugar levels. High blood sugar can lead to a process called glycation, which weakens collagen and causes wrinkles, fine lines, and sagging skin.
• Increasing collagen production: Many foods included in the keto diet encourage collagen production. Collagen is a protein that provides structure to the skin, keeping it firm and wrinkle-free. Foods such as fish, chicken, eggs, and avocados contain omega-3 fatty acids, healthy fats, and collagen, all of which contribute to strengthening the skin's collagen.
• Reducing inflammation: The keto diet has anti-inflammatory effects, which can help reduce redness and inflammation associated with acne and other skin conditions. Inflammation can also contribute to the formation of wrinkles and fine lines.
• Sun damage prevention: The keto diet emphasizes the consumption of omega-3 and omega-6 fatty acids, which are known to prevent sun damage. Sun damage is a major contributor to skin ageing, including the formation of wrinkles and fine lines.

Important considerations:

While the keto diet has the potential to reduce wrinkles and fine lines, it is important to note that individual results may vary. Additionally, the keto diet should be approached with caution as it can be restrictive and may not be suitable for everyone. It is always recommended to consult with a healthcare professional before starting any new diet.

It can regulate oil production

The keto diet can have a positive impact on oil production in the skin. The high oil content in the keto diet can make the skin look dewy and healthy, as more oil is released onto the skin by the oil glands. However, it is important to note that too much fat in the diet might not be great for the skin. The high amounts of fat in the keto diet may increase the production of sebum, which can lead to acne.

The key to regulating oil production is to focus on consuming healthy fats and avoiding excess calories. Coconut oil, for example, is keto-friendly and can help meet increased fat needs without adding carbs to the diet. It also contains medium-chain triglycerides (MCTs), which may boost fat burning. However, it is important to consume coconut oil in moderation, as it is high in calories.

Avocado oil and olive oil are also recommended on the keto diet. These oils are rich in monounsaturated fatty acids, which may support heart health and decrease inflammation. Avocado oil has a high smoke point, making it ideal for frying, while olive oil is better suited for salad dressings due to its low smoke point.

Macadamia nut oil is another good choice on the keto diet, as it has a low glycaemic index and provides fibre and B vitamins. It is important to consult with a nutritionist to determine the appropriate dosage for macadamia nut oil.

In addition to consuming healthy fats, it is also crucial to avoid trans fats, which are found in highly processed foods and unhealthy snacks. These fats can promote inflammation and introduce cell-damaging free radicals.

By focusing on healthy fats and avoiding excess calories and inflammatory trans fats, the keto diet can help regulate oil production in the skin, leading to a dewy and healthy complexion.

It can improve acne symptoms

The keto diet can be beneficial for acne due to its anti-inflammatory nature. The diet's restriction of carbohydrates and focus on healthy fats can help to reduce inflammation in the body, which is a significant promoter of acne. By eliminating simple carbohydrates, in particular, the keto diet targets the body's excess inflammation. This can result in clearer, less congested, and less red skin.

Additionally, the keto diet encourages the consumption of foods that are beneficial for the skin, such as non-starchy vegetables (like spinach and cauliflower), plant-based fat sources (like olive oil and avocado), and fatty fish (like salmon and mackerel). These foods provide essential nutrients and healthy fats that can improve skin health and help prevent acne.

However, it is important to note that the high amounts of fat in the keto diet can also lead to increased sebum production, which may trigger acne breakouts. The diet's impact on acne may vary from person to person, and other factors, such as dairy consumption, can also influence acne symptoms.

A small pilot study found that young women who followed a low-calorie keto diet experienced improvements in their acne, with a reduction in acne severity of 41.5% over a 45-day period. The study also reported improvements in the participants' quality of life, with a 45% increase in their quality-of-life scores.

In conclusion, while the keto diet may help improve acne symptoms for some individuals, it is not a guaranteed solution, and there are other factors to consider, such as the potential for increased sebum production and individual differences in skin types.

It encourages the consumption of skin-boosting foods

The keto diet encourages the consumption of skin-boosting foods, which can be beneficial for the skin.

Alisha Temples, a licensed nutritionist at Fueled and Fed Nutrition, says that "many foods that are beneficial for the skin can be included in a keto diet". These include non-starchy vegetables such as spinach, collard greens, cucumber, and cauliflower, as well as plant-based fat sources like olive oil and avocado. Fatty fish like salmon, mackerel, and sardines are also recommended.

Rachel Daniels, senior director of nutrition at Virtual Health Partners, adds that the keto diet is very low in carbs and refined sugars, which can reduce wrinkles and sagging skin. This is because excess sugar intake leads to a process called glycation, which produces advanced glycosylation end products (AGES) that weaken collagen and lead to wrinkles and sagging skin. Daniels also notes that the keto diet focuses on good-quality fats, including omega-3 and omega-6 fatty acids, which benefit the skin and can prevent sun damage.

Additionally, Daniels points out that the keto diet promotes the consumption of nutrient-dense, low-carb vegetables that are rich in vitamin A retinoids. This vitamin is essential for maintaining glowing and youthful skin as it prevents skin damage, promotes skin cell production, and protects against skin infections.

While the keto diet can be beneficial for the skin, it is important to note that it may not be suitable for everyone. Some people may experience negative side effects, such as acne or the "keto rash", officially known as prurigo pigmentosa. It is always recommended to consult with a medical professional before making any significant dietary changes.

It can cause a keto rash

The keto diet can have both positive and negative impacts on your skin. While it may improve your complexion, it can also cause a rare skin condition known as "keto rash" or prurigo pigmentosa. This condition is characterised by an itchy, red rash that typically appears on the upper back, chest, and abdomen. It can also spread to the neck, face, scalp, and suprapubic region in some cases.

Keto rash is most common among people of Asian descent, particularly young women, although it has also been reported in people of Middle Eastern, Caucasian, Hispanic, and African descent. The exact cause of keto rash is unknown, but it is strongly correlated with the presence of ketosis in the body, which is the state of using stored fat instead of glucose for energy. This is achieved by following a low-carbohydrate, high-fat ketogenic diet.

There are several ways to treat keto rash, including:

• Reintroducing carbohydrates: Increasing carbohydrate intake can help alleviate rash symptoms without completely abandoning the keto diet. A moderately low-carb diet may be a suitable alternative.
• Correcting nutrient deficiencies: Nutrient deficiencies, especially in vitamins A, B-12, and C, have been linked to skin conditions. Eating a variety of colourful fruits and vegetables can help ensure adequate nutrient intake.
• Eliminating food allergens: Many common keto-friendly foods, such as eggs, dairy, fish, and nuts, are also known allergens. Identifying and eliminating specific food allergens can help reduce inflammation and improve rash symptoms.
• Incorporating anti-inflammatory supplements: Certain supplements, such as probiotics, prebiotics, vitamin D, and fish oil, have been clinically studied and found to help improve symptoms of dermatitis.
• Skincare: Taking proper care of the skin is crucial, especially when dealing with inflammatory skin conditions. Using lukewarm water, gentle soaps, and keeping the skin moisturised are recommended.
• Medication: If home treatments are ineffective, a visit to a doctor may be necessary. Antibiotics such as minocycline and doxycycline have been prescribed to treat prurigo pigmentosa effectively.

To prevent keto rash, it is advisable to gradually lower carbohydrate intake, supplement with a multivitamin, and consult a doctor or dietitian when making significant dietary changes.
