A guide to common causes of facial pigmentation, sun protection, and why treatment should match the cause.
# Dark Spots and Facial Pigmentation
Dark spots can develop after acne, sun exposure, hormonal changes, or certain skin conditions. Because different conditions can look similar, identifying the cause is an important first step.
## Common reasons for pigmentation
Post-inflammatory hyperpigmentation can follow acne or irritation. Melasma may appear as brown or grey-brown patches and can be influenced by hormones and sunlight. Freckles and other spots have different causes, so new or changing marks should be assessed rather than self-diagnosed.
## Daily habits that may help
- Use broad-spectrum sunscreen daily and reapply as directed, especially outdoors.
- Wear a hat or seek shade when sunlight is strong.
- Choose gentle skin-care products and avoid repeatedly irritating the skin.
- Do not use unlabelled bleaching creams or products containing undisclosed ingredients.
## Treatment depends on the diagnosis
A clinician may discuss topical treatments, prescription medicines, peels, or device-based procedures when appropriate. Not every treatment suits every skin tone or condition; some procedures can worsen pigmentation if selected or performed incorrectly.
## When to seek assessment
Arrange a professional assessment for persistent pigmentation, irritation, uncertain lesions, or spots that change in size, shape, or colour. Prompt medical evaluation is important for a rapidly changing or unusual spot.
