When a specific skin problem comes about, many people quickly jump to the conclusion that it is because their skin is simply genetically predisposed to that particular condition. While it is true that genetics play a role in your skin’s appearance to an extent, you might be surprised to find that many common skin concerns arise due to external factors over which you have much more control than you might think. If your body is deficient in certain nutrients, for example, it may show up in the form of dryness, itchiness, or redness on your skin. In the case of a tryptophan deficiency, these are the exact symptoms that you are likely to notice first.
What Is Tryptophan?
Tryptophan is an essential amino acid, meaning that it needs to be obtained from external sources because your body is unable to synthesize it on its own. As a result, when you do not get enough tryptophan through diet and supplements, there can be negative health effects on your entire body, including your skin. In particular, tryptophan is important to your skin’s health and appearance, as well as your overall wellness, because it is the precursor to a variety of different substances, including niacin. Niacin is a type of B vitamin and is involved in toxin removal, promoting healthy circulation, and regulating hormone production within the body . Because tryptophan is a precursor to niacin, a deficiency in this essential amino acid can lead to a number of skin and health concerns, including a condition called pellagra.
Signs of Pellagra
Although pellagra is a vitamin deficiency, it can be caused by a lack of either cellular niacin or its precursor, tryptophan . The first and most noticeable signs of pellagra show up on the skin in the form of dermatitis, redness, and even lesions that tend to become more pronounced with sun exposure . Following these skin symptoms, you may notice additional concerns related to pellagra, including diarrhea and dementia. In the case of pellagra, these negative effects on the skin can be reversed by getting enough tryptophan through diet, supplements, and even topical skincare products that contain amino acids.
Anti-Aging Benefits of Niacin
While pellagra is an extreme example of the possible negative effects that a tryptophan deficiency could have on your skin and overall health, this particular amino acid can also play a role in anti-aging strategies for your skin. Niacinamide is a derivative of niacin, which requires an adequate amount of tryptophan within the body. Niacinamide has been shown to help enhance the skin’s natural barrier function, which keeps moisture sealed inside while simultaneously keeping toxins and other harmful substances out . In addition, studies have found that niacinamide can help to reduce the appearance of lines, wrinkles, and age spots, as well as inhibit a process known as glycation, which can damage proteins like the collagen and elastin in your skin [2, 3].
Replenishing the Skin with Amino Acid Skin Care
As you can see, there are many different working parts that need to be just right in order for your skin to function properly and look and feel healthy and youthful. This is where regularly using amino acid skin care products can have a large impact, as amino acids play a role in many different specific functions within the skin, including serving as precursors to substances like niacin. Similarly, because amino acids are needed in order to synthesize any protein, they play a key role in triggering your skin to produce more collagen, which, in turn, helps to diminish the appearance of lines, wrinkles, and sagging skin.
