3. Persistent redness or rashes.
Chronic facial redness, with visible blood vessels or inflammatory outbreaks, can be a sign of rosacea. If lesions appear on other parts of the body, they may be associated with allergic reactions, infections, lupus, or even autoimmune diseases.
4. Brittle or spotted nails.
Although not skin per se, nails are part of the integumentary system. Fragile nails, nails with dark lines, or changes in their shape can indicate nutritional deficiencies, heart disease, or thyroid problems.
5. Extreme dryness and flaking.
Dry skin that doesn’t improve with moisturizing can be linked to conditions such as hypothyroidism, psoriasis, or atopic dermatitis. It could also be a sign of chronic dehydration or poor nutrient absorption.
6. Appearance of bruises without apparent cause
If the skin bruises easily and without obvious blows, there may be a problem in coagulation, vitamin K deficiency or blood disorders such as thrombocytopenia.
