The difference between dry and dehydrated skin

Although the symptoms overlap, there are distinct differences:

• Dry skin feels rough, appears flaky, and may itch or crack.
• Dehydrated skin looks dull, feels tight, and shows accelerated signs of aging, such as fine lines and sagging.

The Pinch Test: Lightly pinch a small area of your skin (cheek or back of the hand). If it doesn’t bounce back within three seconds, your skin is likely dehydrated.

Dehydration occurs when your body loses more water than it takes in. To prioritise essential functions, your body diverts water to vital organs which is beneficial for overall health but can negatively impact your skin.

The most common cause of dehydration is insufficient water intake. However, other factors like excessive sweating during exercise or in hot weather can also contribute. Prolonged sun exposure is another culprit, as UVA rays increase oxidants and free radicals in the skin, accelerating the aging process. Conditions like sunburn, heatstroke, fevers and diarrhea can further deplete your hydration levels.

Certain medications, such as antihistamines and laxatives, can also lead to dehydration. In some cases, underlying medical conditions like hyperhidrosis (excessive sweating) or diabetes may be responsible. If your symptoms persist despite increasing hydration, it’s a good idea to consult your doctor for further evaluation.

The primary cause of dry skin is often environmental factors. Low humidity, frequent or prolonged bathing, and the use of abrasive products can strip your skin of its natural oils.

It’s also important to review the ingredients in the soaps and detergents you use, as these may contribute to dryness. Additionally, your overall health can play a significant role. Conditions such as malnutrition, sudden weight loss, dermatitis or even chronic kidney disease can lead to skin dryness. Identifying and addressing these factors is key to restoring your skin’s moisture balance.

• There are several simple remedies you can try at home to improve your skin’s condition. For dehydrated skin, ensure you’re drinking plenty of water and incorporating electrolyte drinks into your routine. The added sodium, potassium, and magnesium can give your hydration levels a much-needed boost. For dry skin, investing in high-quality moisturizers, serums, or lotions is essential. Just be sure to select products tailored to your skin type. Our expert team is always available to guide you in making the best choices.
