Brittle nails and dry skin are common as people age, and they often result from a combination of natural aging processes, lifestyle factors, and underlying health conditions. Here’s a breakdown of the main causes:
🧬 Natural Aging Process
-
Reduced Oil Production: Sebaceous glands produce less oil over time, leading to drier skin and less flexible nails.
-
Slower Cell Turnover: Skin regenerates more slowly, leading to a rougher texture and dryness.
-
Collagen and Elastin Decline: These proteins help skin and nails stay firm and strong. Their reduction weakens nail structure and skin elasticity.
-
Thinner Skin and Nails: The skin becomes thinner and more fragile, and nails can become thinner and more prone to splitting.
💧 Hydration & Nutrition
-
Dehydration: Older adults may drink less water, contributing to dryness.
-
Nutrient Deficiency: Lack of biotin, vitamins A, C, D, E, zinc, and omega-3 fatty acids can weaken nails and dry out skin.
-
Poor Diet: Diets low in protein and healthy fats impact keratin and lipid production.
☀️ Environmental & Lifestyle Factors
-
Sun Damage: Cumulative UV exposure breaks down collagen and dehydrates skin.
-
Frequent Hand Washing or Harsh Soaps: Strips natural oils from the skin and nails.
-
Cold, Dry Weather: Lower humidity draws moisture out of skin and nails.
-
Use of Nail Polish Removers: Especially those with acetone, which dries and weakens nails.
🩺 Medical Conditions
-
Thyroid Disorders: Can lead to dry skin and brittle nails.
-
Diabetes: Affects circulation and skin health.
-
Psoriasis or Eczema: Skin conditions that become more pronounced with age.
-
Peripheral Circulatory Issues: Can reduce blood supply to extremities, affecting nail and skin health.
🧴 Tips for Prevention & Management
-
Use moisturizers with ceramides or urea.
-
Apply cuticle oils and nail hardeners sparingly.
-
Wear gloves when doing dishes or cleaning.
-
Stay hydrated and eat a balanced diet.
