Brown marks on the face are often grouped together as “pigmentation”, but that word does not identify the cause. If you are researching pigmentation treatment near Preston, the useful first question is what type of mark you have—not which procedure to book.
Melasma and sun spots can both affect appearance, yet they need different expectations and assessment. This guide explains the distinction and the questions to bring to a consultation in Longridge.
What is a sun spot?
A solar lentigo, commonly called a sun spot or age spot, is a benign pigmented lesion associated with accumulated ultraviolet exposure. These marks often appear on sun-exposed areas, including the face and backs of the hands, and can persist through winter. [1]
That description is not a way to diagnose a mark yourself. Several conditions can look similar, and uncertainty may require further investigation before cosmetic treatment. A confirmed harmless sun spot does not have to be treated. [1]
How is melasma different?
Melasma usually produces flat brown or greyish patches on the face. Pregnancy, hormonal medicines and sunlight can contribute. It can occur in different skin tones and is not contagious. [2]
Unlike a promise to “remove a blemish”, melasma management needs a longer view. The British Association of Dermatologists explains that there is currently no cure, although treatment may improve its appearance. Pigmentation can return after treatment stops. [2]
When should your GP check a mark?
Arrange a GP appointment for a mole that changes size, shape or colour, becomes painful or itchy, or is inflamed, bleeding or crusty. The NHS also advises assessment of a new or unusual mark that has not gone away after a few weeks. [3]
Do not use a cosmetic procedure to deal with an unexplained changing mark. Tell the assessing clinician when it appeared, how it has changed and whether you or a family member has had skin cancer. A referral for further checks does not necessarily mean cancer. [3]
Why the same laser plan may not suit both
For confirmed sun spots, options can include pigment-targeting laser, light treatments and chemical peels. Procedures can leave darker or paler patches, sometimes permanently. Choosing no treatment remains reasonable. [1]
With melasma, laser response is variable. Laser or peels can worsen pigmentation; other risks include irritation and scarring. These possibilities should be discussed before committing. [2]
A melasma plan should consider skin tone, the depth of pigmentation and possible triggers. There is no single best treatment for everyone. [4] Ask why the proposed approach fits your assessment, what improvement is realistic, and how a limited response would be managed.
What can you do between appointments?
Sun protection is part of melasma management. The American Academy of Dermatology recommends shade, a wide-brimmed hat and broad-spectrum sunscreen of at least SPF 30. A tinted sunscreen containing iron oxide may be worth discussing. [4]
Bring a list of skincare products and medicines to your consultation. Explain previous treatments, irritation and any pregnancy or breastfeeding. Ask for a written plan covering preparation, aftercare, costs and review appointments. Avoid changing several products at once without discussing how they fit the plan.
Frequently asked questions
Can I identify melasma from a photograph?
A photograph can help explain your concern, but an assessment may be needed to distinguish melasma from another condition. A dermatologist may use closer examination or further tests when the diagnosis is uncertain. [4]
Will pigmentation treatment permanently clear my skin?
No permanent clearance should be assumed. Melasma can recur, and sun protection remains relevant after sun-spot treatment. Ask about maintenance rather than relying on a guarantee. [1] [2]
Do I need to book a procedure straight away?
No. Start with assessment and take time to consider the explanation, alternatives and risks. You can choose to wait or not proceed.
