For a long time, skincare was mostly dealing with the use of cleansers, creams, and serums. Though, the relationship between the skin and the internal body processes, particularly in the gut, has been newly discovered by science. The connection between the gut and skin is the explanation of the occurrence of these symptoms that the skin is affected by local or systemic infections, which is the case of gut inflammation.

What Is the Gut-Skin Axis?

The gut-skin relationship involves how the gut microbiome which includes bacteria, fungi and other microbes that live inside the digestive tract and the skin health. A well-balanced microbiome is the main factor for digestion, nutrient absorption, and immune system. However, if it is upset (dysbiosis), the microbiome can cause an inflammation of the whole body, which is the skin that can be the source of acne, rosacea, eczema, or early aging of the skin.

How Gut Health Affects Skin:

  1. Inflammation and Acne:The proliferation of bad bacteria in the gut causes them to produce toxins which will activate the immune system. This low-level inflammation can lead to aggravation of acne and other skin issues.
  2. Nutrient Absorption:The gut will be the area where are absorbed the nutrients that will benefit the skin such as zinc, vitamin c, vitamin e, and essential fatty acids. If the gut is weak, the skin will also be weak with the lack of nutrients needed for the repair and glow.
  3. Hormonal Balance:Intestines along with the community of bacteria living there are very involved in the breakdown and metabolism of hormones. A disordered gut can intensify the swings that cause a breakout, for example, in the area of the jaw or around the time of your period.
  4. Skin Barrier Function:A weakened gut has the capacity of the impaired skin barrier so that it is more vulnerable to dryness, irritation, and sensitivity.

  • Dairy (for some people): Has the potential to affect hormones and cause the situation with breakouts to worsen.
  • Highly Processed Foods: The presence of preservatives and additives in such kinds of food may lead to microbiome imbalance.
  • Excess Alcohol: Drinking excess alcohol makes the skin dry and has an impact on gut microbiome.

The gut-skin axis is still related to the diet however, the main factors that influence it are stress, sleep, and medication. Stress that lasts for a long time changes gut bacteria, while unhealthy sleep has a negative impact on skin repair function. Besides that, too many antibiotics that a person is taking may also harm the gut microbiome, which may consequently cause a series of skin flare-ups over time.
