What should you know about dark spots diabetes?

Diabetes can affect skin health through changes in circulation, healing, and susceptibility to irritation or infection. Darkening may appear after inflammation, scratching, or a healed rash. Velvety darker skin in body folds can have a different cause and deserves assessment. The colour, texture, location, and speed of change help a clinician narrow the possibilities. Similar-looking patches may be [Post-Inflammatory Hyperpigmentation](/conditions/post-inflammatory-hyperpigmentation/) or [Tinea Versicolor](/conditions/tinea-versicolor/), rather than a diabetes-related change.

Note when the spots began, whether they itch or hurt, and whether they followed a cut, rash, shaving, or friction. Photographing them in consistent lighting can help show change over time. Keep the area gently cleansed and moisturised, avoid picking, and use sun protection on exposed skin. If diabetes is known, follow the established glucose-care plan and arrange a dermatology or primary-care review before trying bleaching products or procedures. Depending on the diagnosis, options may include [Skin Brightening Treatment](/treatments/aesthetic-procedures/skin-brightening-treatment/) or another targeted approach.

Arrange a prompt assessment if a spot changes quickly, bleeds, becomes painful, develops an open area, or is joined by warmth, swelling, pus, or fever. Seek timely medical advice for new widespread darkening, marked thirst or urination, unexplained weight change, or a wound that is slow to heal. These features need clinical assessment rather than cosmetic treatment.

Could the pattern fit post-inflammatory pigmentation, a fungal condition, or another skin problem? Do I need diabetes testing or a review of existing glucose control? Which ingredients or procedures are suitable for my skin and medical history?
