The Importance of a Nutritional Treatment Approach for Acne

Key vitamins & minerals required for healthy skin
Pantothenic acid (Vitamin B5) is essential for our ability to cope with stressful events, as it supports the adrenal glands in the making of hormones that counteract the stress response. It’s involved in the metabolism of fats and is required for the synthesis of steroid hormones<4>. This is important, because issues with metabolising fats may affect the sebum in the skin. In addition, stress in many forms poses as an aggravating factor in acne lesions<5>. Zinc is extremely important for our skin. It’s important for normal skin renewal processes while being essential for wound healing<6>. Zinc is involved in the metabolism of androgen hormones and is an essential trace mineral that is a component in over 200 enzymes in the body. Our diets can often be lacking in this important mineral due to soil deficiencies<7>,<8>. Deficiencies in zinc can result in delayed wound healing, impaired immune function, and hormonal imbalances. Similarly, deficiencies in nutrients such as Vitamin A and Niacin (Vitamin B3), can result in skin and hormonal problems6. Folic acid deficiency can also produce changes in the skin<9>. Folate (Vitamin B9) is essential for proper cell division, DNA synthesis, replication, and repair. This role is particularly important within skin, which when functioning properly is a proliferating tissue that depends upon a balance of growth and differentiation to maintain homeostasis. Adequate levels are required for the synthesis of new cells, which promotes the vital processes of skin turnover, barrier formation and wound healing<10>. Silica is a component of collagen and is therefore essential for the strength and resilience of connective tissue is therefore required for the proper integrity of the skin<11>. Like Silica, Copper is important for connective tissue formation and is also involved in the production of elastin and collagen. Copper is also a component of the antioxidant Super Oxide Dismutase (SOD) and may, therefore, assist in protecting the body from the damaging effects of free radicals <12>. Biotin also contributes to the maintenance of normal skin<13>, with biotin deficiency resulting in a variety of skin complaints. Other ingredients for skin health The skin is composed of protein, water, and fat. Ensuring you are getting a good intake of the skins building blocks, is important for skin health. Collagen represents a family of 28 different proteins, which account for 30% of the total protein mass in the human body and plays a pivotal role in the structure of several tissues, including the skin, providing rigidity and integrity<14>. Certain nutrients such as Silica and Copper are necessary for collagen formation within the body and preliminary evidence also suggests that consumption of hydrolyzed collagen may have beneficial effects in the skin. In a double-blind placebo-controlled trial of 69 healthy female adults, oral supplementation of collagen peptides was shown to improve skin elasticity, a statistically significant result when compared to placebo<15>. Essential Fatty Acids (EFAs), such as those found in fish oil and chia seeds, are necessary for skin function. Animal studies have provided a wealth of knowledge on the cutaneous consequences of EFA deficiency. Experimentally induced EFA deficiency has resulted in changes that have been shown to be similar in all species and have presented as follows<16>:- The epidermis becomes thin and discoloured, scaly and rough
- The skins sebaceous glands increase in size
- The viscosity of sebum (or oily secretion of the sebaceous glands) increases.
- There is excess production of Keratin, a skin protein, in the sebaceous ducts (hyperkeratosis)
- Skin capillaries become weakened
- There is impaired or delayed healing of wounds, possibly as a result of defective collagen
- There is increased water loss from the skin into the atmosphere via diffusion and evaporation (transepidermal water loss)
