What should you know about Kiehl's uneven skin tone?

Uneven tone is a visible change rather than a diagnosis. Darker patches may follow sun exposure, hormonal influences, or inflammation from acne, eczema, irritation, or an injury. Melasma often appears as patchy brown or grey-brown areas, commonly on the face. Sun spots and broader signs of sun-damaged skin can also create contrast between nearby areas. When a mark develops after inflammation settles, it may be post-inflammatory hyperpigmentation.

The colour, pattern, timing, and skin history help a clinician narrow the possibilities. A photo taken in consistent lighting can help you track gradual change, but it cannot replace an examination when the appearance is new or changing.

Use broad-spectrum sunscreen as directed, reapply when appropriate, and add shade, clothing, or a hat during strong sun. Keep cleansing gentle and moisturise if the skin feels dry. Avoid picking spots and stop products that cause burning, persistent stinging, or a rash. Introducing one new active product at a time makes irritation easier to identify.

A clinician can check the pattern before suggesting treatment. Options may include a tailored skin-brightening treatment, a chemical peel, or an IPL photofacial, depending on the cause, skin type, and risk of further pigment change. These procedures need individual assessment and careful aftercare.

Arrange a dermatology assessment if the colour change is new, spreading, persistent, or difficult to distinguish from a mole or other mark. Seek prompt medical advice for a spot that changes in size, shape, or colour, bleeds, repeatedly crusts, becomes painful, or does not heal. Get urgent help for sudden widespread colour change with facial swelling, breathing trouble, or other severe symptoms.

Ask what pattern or trigger best fits the change, whether any current products could be irritating your skin, and which treatment is appropriate for your skin type. You can also ask how long to test a routine, what changes should make you stop it, and what aftercare is needed after a procedure.
