The Body Signs Series #3 – Dry Skin

Dry skin. Seems like a common problem which we often try to solve with lotions and potions… but sometimes hydrating your skin is not enough. For healthy, glowing skin you also need sufficient amounts of these nutrients:

👉Vitamin A, which plays a key role in skin cell proliferation & differentiation, photo protection (from UV light), and overall skin health.

  • It is also an important epigenetic regulator that influences the expression of hundreds of genes. 
  • Other signs of deficiency include acne, eyesight problems, gingivitis, bone & joint pain, skin hyperpigmentation, poor wound healing, psoriasis and more.
  • Zinc deficiency can impair vitamin A metabolism & function

👉Biotin, which plays a key role in the production of fatty acids that nourish the skin, as well as energy metabolism and cell membrane integrity.

  • It is also another potent regulator of genetic expression.
  • Other signs of deficiency include sore & reddened tongue, hair thinning and brittleness, slow cognition, seborrheic-like dermatitis and more.

👉Zinc, which can reduce skin inflammation and is needed for collagen production and wound healing.

  • And (no surprise here) this mineral also plays a role in regulating gene expression.
  • Other signs of deficiency include acne, poor vision, cracks in corners of mouth, geographic tongue, impaired wound healing, hair thinning and brittleness, loss of taste, weak nails, diarrhea and more.
  • Note: zinc, copper, iron & calcium all interact in each other’s absorption and metabolism.

👉Essential fatty acids, which are needed for healthy cell membranes, skin barrier integrity, protection from UV light, wound healing and reduction in skin sensitivity.

  • Remember, we have trillions of cells with fatty membranes and our brain is made up of nearly 60% fat, which makes healthy dietary fats an important component of our body’s physical structure.
  • Other signs of deficiency include acne, reduced visual acuity, dry hair, dandruff, weak nails, parasthesia and neuropathy, impaired memory, increased thirst, eczema, dermatitis, poor mental health and more.

✳️ The above are only some of the functions & deficiency signs of these nutrients, our physiology is quite complex and many nutrients interact in multiple ways, so we should not view them in isolation.

✳️✳️ As always, it is recommended to check your nutrient levels and speak with your healthcare provider before coming to conclusions and starting any supplementation.

Your body is talking, are you listening? 👀
