Preventing clogged sweat ducts involves:

| Type | Depth | Presentation | Key Feature | |------|-------|--------------|--------------| | | Stratum corneum (most superficial) | Clear, fragile, 1–2 mm vesicles without erythema | "Dewdrops on skin"; no itching | | Miliaria Rubra (Prickly Heat) | Intraepidermal (mid-epidermis) | Red papules and vesicles, intense pruritus, burning | Most common type; anhidrosis in affected areas | | Miliaria Pustulosa | Intraepidermal (superficial) | Pustules on an erythematous base | Often represents infected rubra; purulent | | Miliaria Profunda | Dermoepidermal junction (deep) | Flesh-colored papules, minimal erythema | Occurs after repeated episodes of rubra; compensatory hyperhidrosis elsewhere |

⭐⭐⭐⭐ (4.5/5) – Comprehensive, clinically actionable, and well-structured, though newer topical keratolytics (e.g., salicylic acid) deserve more investigation.
