Magnesium is one of the body’s most important minerals, involved in over 300 biochemical reactions. It promotes muscle and nerve function, maintains blood pressure, supports bone health and encourages cellular healing. And yet many of us unknowingly run low on magnesium, thanks to a poor diet, chronic stress and some medical conditions.

And when levels of magnesium drop, the body starts to display them externally — often long before there are internal signs of trouble. As the face is a reflection of our health and what occurs on the inside manifests on the outside, subtle variations in the skin, eyes and even the face muscles can mark a deficiency that you should investigate.

According to Chennai-based Dr Riya Menon, MD (Nutrition & Metabolic Health), magnesium deficiency is "one of the most under-recognised sources of fatigue, skin sluggishness and premature aging". She warns that even small clues in the face could serve as early-warning signals, prompting people to do something about deficiencies before they compromise health further.

Recognizing these visual cues can be a key in addressing the imbalance through diet, supplementation and lifestyle changes.

Dull and Dry Skin

Low magnesium impacts hydration balance and collagen synthesis, so skin may appear dry, dull or textured. This is because magnesium plays a role in regulating cellular repair as well as holding up the skin’s elasticity. Lack of it can lead to prematurely ageing facial contours.

Muscle Twitches and Facial Spasms

Magnesium regulates muscle contraction. A shortage may lead to little random twitches in the eyes, lips or cheeks. Such spasms may initially be bothersome, but develop into recognizable discomfort if ignored.

Dark Circles and Puffy Eyes

Dark circles and bags under the eyes can be exacerbated by stress and poor sleep, which are in turn aggravated by low magnesium. And because magnesium helps regulate cortisol and supports restful sleep, low levels can manifest themselves in tired, puffy eyes.

Acne and Breakouts

Magnesium also plays a role in inflammation and balancing hormones, which can affect acne problems. If you’re breaking out — but nailing your skin care routine — a diet imbalance could be to blame.

Premature Wrinkles

Magnesium, by virtue of its support for antioxidant defences, contributes to the acceleration of oxidative stress in skin cells at low levels. This leads to an accelerated development of wrinkles and skin slackening especially in the area around the forehead and eyes.

Your body can tell you a lot about your health and that includes the face, where magnesium deficiency is concerned. From tired-looking skin to long-lasting dark circles, these early signs are enough to prompt a closer look at diet and lifestyle. Catch these symptoms — and replenish your magnesium levels— early in order to resurrect both your health and that natural glow you miss.
