Stages of Dermatitis

Dermatitis moves through three overlapping phases - the same patch of skin can show all of them over a bad month. Knowing the phase tells you what the skin needs.

Acute stage: the flare

• Intense itch, redness, warmth, swelling
• Tiny fluid-filled blisters that weep and form yellowish crusts
• Skin needs: calming - cool compresses, the right anti-inflammatory cream prescribed early, and resisting the scratch with everything available

Subacute stage: the simmer

• Redness settles into dry, scaly, flaky patches
• Itch persists at a lower but constant level - this is where scratching quietly does its long-term damage
• Skin needs: generous moisturiser to rebuild the barrier, continued anti-inflammatory treatment as advised, trigger avoidance

Chronic stage: the thickening

• Weeks to months of scratching produce lichenification - leathery, thickened skin with deep skin lines, often darker than surrounding skin
• Cracks (fissures) appear on hands, heels and finger tips - painful, and open doors for infection
• Skin needs: months of barrier repair - heavy moisturisers, patience, and breaking the itch-scratch cycle at its root

The cycle that drives all three

Itch -> scratch -> barrier damage -> more inflammation -> more itch. Every treatment that works - moisturiser, steroid, antihistamine at night, short nails, cotton gloves on children - is a different way of cutting this loop.

One-line summary

Dermatitis runs acute (weeping, red, furious), subacute (dry, flaky, simmering) and chronic (thick, leathery, cracked) - all three driven by one itch-scratch cycle that every effective treatment exists to break.
