The skin is the body’s largest organ and one of its most visible messengers. Changes in the skin often reflect internal health, immune reactions, infections, or even cancer. Yet many skin warning signs are dismissed as cosmetic problems.

Dermatologists emphasise that while many rashes and acne flares are benign, persistent or unusual changes require evaluation.

Common skin problems and what they may signal

• Acne: hormonal shifts, stress, or metabolic issues.
• Rashes: allergic reactions, infections, or autoimmune conditions.
• Persistent itching: liver, kidney, or blood disorders.

Skin cancer warning signs

Any changing mole, non-healing sore, or rapidly growing lesion should be assessed. Early detection dramatically improves outcomes.

Why self-treatment can delay diagnosis

Over-the-counter creams may temporarily mask symptoms without addressing the cause. This delay can allow serious conditions to progress.

Protecting skin health

• Sun protection
• Avoiding harsh or unregulated products
• Seeking review for persistent changes

Bottom line: Skin changes are data. When they persist or evolve, they deserve medical attention.
