"Discussions of metabolism usually focus on its relationship to weight, which often depends on one or another type of diet, nutritional supplements, or lifestyle," says Dr. Lindsey Clark , metabolic medicine specialist and antiaging expert . "When we focus on boosting our digestive metabolism, we often forget that our skin also depends on our metabolism."
Your skin is one of the most important parts of your body. A balanced and functioning metabolism is the key to healthy skin at all stages of life. Metabolism affects your skin. Especially since your skin has its own metabolism.
"Skin metabolism refers to the rate of cell renewal and the biological processes that occur between epidermal and dermal cells to produce collagen and repair damage caused by UV rays or aging," says Dr. Clean.
old age
Your skin's metabolism also slows down, as does your digestive metabolism, as you age. This can be illustrated by the example of "baby skin". When we are children, skin cells are shed every 2 weeks, compared to 22 days for adults and 50 days for adults. The rate of skin cell renewal is directly related to how soft, supple and supple your skin is.
Slow cell turnover not only affects the quality of your skin, but also the way skincare products work on your skin. As with the digestive system, our absorption of nutrients becomes less efficient as we age, and the same goes for the skin. Malabsorption of nutrients can further complicate your skin's metabolic capabilities.

The environment can have a big impact on your metabolism and skin health. UVA rays are not absorbed by the ozone layer and can penetrate the dermis, the deepest layer of human skin. UV rays have a variety of effects on the skin, including immediate redness and darkening of the skin, the formation of fine lines, wrinkles and age spots.
Also, UVA rays can enter through windows, which is why doctors and dermatologists recommend applying sunscreen every day, even when you're not outdoors. UVB is another form of UV light, and unlike UVA, not all UVB rays reach the Earth because some of them are absorbed by the ozone layer. Because UVB rays are shorter and have a higher frequency, they cause more skin damage when they penetrate the epidermis (top layer of skin).
UVB radiation causes sunburn and delayed tanning. It plays an important role in the development of all types of skin cancer by damaging the DNA of skin cells and the immune system. UVB is also important for the synthesis of vitamin D3.
Another environmental variable that can affect skin metabolism is environmental pollution. In 2010, researchers began to understand how microparticles emitted by industry and automobiles can disrupt metabolism, destroy skin microflora, and contribute to cancer and aging.
food
"You are what you eat" is a famous saying familiar to many of us. The point of this saying is that nutrient-dense foods help skin cells regenerate and heal themselves. A balanced diet is essential for healthy skin function.
Eating processed foods won't harm your skin as long as they are part of a balanced diet and eaten in moderation. However, if your diet consists mostly of processed foods, you're missing out on important nutrients that are important to skin health and the body's ability to protect systems from infection.
emphasize
When the mind or body is under stress (due to a real or imagined threat), our brain releases hormones that cause the stress hormone cortisol to be released from our adrenal glands. Our skin has receptors for these stress hormones and their activation leads to various changes in our skin such as:
- Increased inflammation
- Impaired wound healing
- Increases oil and sebum production
- Compromised immunity to infections
Not only can stress cause changes in our brain and body chemistry that lead to skin changes, it can also contribute to our behavioral responses (conscious or unconscious). For example, some people touch their face when they're nervous, keeping whatever they're holding to their face can make acne worse.
When we are very stressed, we drift away from our healthy habits. We can spend less time taking care of ourselves if we sleep less, eat junk food, don't exercise, and don't wash our faces regularly. All of these activities can have a negative effect on our skin.
