The line between essential and non-essential nutrients used to be precise. The first criterion was based on the definition of essential – the nutrient is or is not vital. The second related to the body’s ability or inability to produce the nutrient on its own steam; if it can, the nutrient is ‘non-essential’ and if it cannot, it is ‘essential’ and must be obtained through food or supplementation. However, there is a category between the two and, in addition to topical dry skin care, you may need supplementation that you previously thought unnecessary. The category between essential and non-essential is known as ‘conditionally essential’. It refers to nutrients that the body is inherently capable of synthesizing, but no longer being produced at all or in adequate quantities due to factors such as stress, illness or aging. Many of these nutrients are related to health factors that are important in dry skin care. Which nutrients should concern you? Two of the most important are the amino acids cysteine and methionine. Cysteine is the amino acid in alpha-keratin, the major protein found in hair, skin and nails. It promotes collagen production and is largely responsible for skin elasticity and texture. Both methionine and cysteine are also powerful antioxidants and detoxifying agents. The body’s ability to fighting free radicals and rid the body of toxins are vital functions for dry skin care and prevention. Cysteine is a non-essential amino acid – it can be synthesized by the body – but only with adequate quantities of methionine. As methionine production is reduced by stress, illness and aging, cysteine production also decreases. As most dry skin is caused by loss of moisture and exposure to harsh chemicals, it is important to use a good topical dry skin treatment that keeps moisture in and chemicals out. However, if you have been under stress, ill or are getting on in years, it’s also a good idea to supplement your diet with these amino acids.
