Melasma, Freckles or Sun Spots? How to Tell Types of Pigmentation Apart

Short answer

Melasma, freckles and sun spots are told apart by location, age of onset and seasonal change. Melasma is a broad, symmetrical, hormone-related patch on the cheeks, forehead and upper lip. Freckles start in childhood and fade in winter. Sun spots are sharply defined and stay all year. In Denizli, Dr. Tuba Çelebi Kayhan identifies your type at an examination.

Melasma, freckles and sun spots can sit side by side on the same face. All three are brown and all three darken in the sun, yet their causes, their depth and the way they respond to treatment are quite different. Knowing which one you have is the first step towards knowing what to do about it.

At our clinic we give each mark its own name before planning any treatment; pigmentation treatment in Denizli starts with this distinction. The clues below do not replace an examination, but they show you what to pay attention to when you describe your pigmentation.

How Are Different Types of Pigmentation Told Apart?

Three questions are the most useful: when did the mark start, where on the face or body does it sit, and does it change with the seasons?

Type of markWhat does it look like?When and where does it appear?
MelasmaBroad, symmetrical, brown or greyish, with irregular edgesIn adulthood; cheeks, forehead, bridge of the nose, upper lip, chin
Freckles (ephelides)Small, light brown, scattered dotsIn childhood; sun-exposed face, shoulders and arms; darker in summer
Sun spot (solar lentigo)Larger than a freckle, flat brown mark with clear bordersFrom middle age; face, backs of the hands, chest; stays in winter
Post-inflammatory pigmentationBrown mark in the shape of an old spot or woundAt any age; where inflammation has been, more visible in darker skin
BirthmarkCafé-au-lait, blue-grey or dark brown, same shape for yearsFrom birth or the first years of life; anywhere on the body

How Do You Recognise Melasma?

The most striking feature of melasma is its symmetry: similar patches appear on both cheeks, on both sides of the forehead or above the upper lip. The edges are irregular enough to look like a map, and the colour can shift from brown towards grey.

Hormones play the decisive role. It typically starts during pregnancy or while taking the contraceptive pill, and it darkens with sun and heat. Melasma that appears in pregnancy follows a course of its own: pigmentation during pregnancy often fades after the birth, and both protection and the timing of treatment change around this period.

Why does melasma darken in summer and never fully clear in winter?

Sunlight and heat stimulate the pigment cells in melasma again, so the patch becomes more obvious in summer. It may lighten a little in winter, but because the hormonal trigger is still there, it does not disappear completely. A mark that vanishes entirely with the season points to freckles rather than melasma.

Why Do Freckles Fade in Winter While Sun Spots Stay?

In freckles the number of pigment cells does not increase; the existing cells simply produce more pigment in the sun. When there is less sun, production falls and freckles fade in winter. Freckles run in families and are more noticeable in fair-skinned people with red or blonde hair.

In a sun spot, years of sun damage have increased the number of pigment cells. That is why the mark stays in place regardless of the season, and new ones are added with age. The marks known as age spots or liver spots mostly belong to this group too.

How Can You Tell a Mark Left After a Spot or Wound?

Post-inflammatory pigmentation appears where inflammation or injury has affected the skin. It can follow a spot, an insect bite, eczema, a burn or a harsh cosmetic treatment. The mark often keeps the shape of the lesion that caused it: a round mark after a spot, a line after a scratch.

These marks usually fade on their own over months, but sun and fresh inflammation make the process longer. They are more visible in darker skin and can last longer there.

How Are Birthmarks Distinguished from Other Marks?

Birthmarks are present from birth or appear in the first years of life; they show no obvious change with sun or season. The main ones are:

  • Café-au-lait mark: a flat mark the colour of milky coffee, with clear borders.
  • Naevus of Ota: a deep, blue-grey mark around the eye and temple.
  • Mongolian spot: a blue-grey mark on the lower back and buttocks of babies, which fades over the years.
  • Congenital mole: a brown or dark lesion, sometimes hairy, which may be raised.

Congenital moles are not pigment marks but belong to the mole group, and depending on their size they may need regular monitoring.

When Should a Mark Be Examined Like a Mole?

Not everything that is flat and brown is a harmless mark. If any of the following features are present, the mark needs to be examined as if it were a mole:

  • A mark that appears for the first time in adulthood and keeps growing
  • A mark containing more than one colour, or black or red areas
  • A mark with irregular edges, where one half does not match the other
  • A mark that itches, bleeds or crusts
  • A mark that slowly spreads on older, sun-damaged facial skin and has an uneven tone

The last point matters: a superficial type of melanoma called lentigo maligna can look like a sun spot in its early stage. For this reason, before applying a cream or laser to a suspicious mark, we carry out a mole check with dermoscopy.

Can You Work Out the Type of Mark at Home?

Some clues can be noticed at home. Looking through old photos to see when the mark first appeared, comparing how it looks in summer and winter, and noting any link with pregnancy or the pill all genuinely help the examination.

A definite distinction, however, means looking at how deep the pigment sits and how it is spread in the skin. At the examination we use daylight, magnification, special light where needed and a dermatoscope. Two different types of pigmentation on the same face also make telling them apart at home harder.

How Does the Type of Mark Change the Treatment?

Sun spots respond well to light and laser; freckles fade but return with the sun; melasma needs long-term cream treatment and strict sun protection. In post-inflammatory pigmentation, the source of the inflammation is treated first, and some birthmarks need no treatment at all. You can see which method stands out for which mark in our comparison of pigmentation treatment options.

What Should You Bring to a Pigmentation Examination in Denizli?

It speeds up the examination if you remember when the mark began, whether it darkens in summer, whether it is linked to pregnancy or hormonal medication, and which creams you have used so far. If you have old photos showing the mark, bring them as well. After the examination we plan melasma and sun spot treatment that suits your type of pigmentation together with you.

Frequently asked questions

Does melasma only affect women?
No. Melasma is a more prominent problem in women, but it is also seen in men. In men too, sun and heat are the most important triggers.
My freckles are increasing with age. Are they still freckles?
True freckles begin in childhood and do not increase with age; they may even become fewer. Dots that appear for the first time in adulthood and do not fade in winter are usually sun spots, and in fair-skinned people the two can be present together.
What does it mean if a mark looks grey or bluish?
Grey and bluish tones suggest that the pigment sits in a deeper layer of the skin. This colour is seen in deep melasma and in birthmarks such as naevus of Ota; these marks respond more slowly to treatment.
Does a birthmark grow over time?
Café-au-lait marks grow in proportion to the body as a child grows; this is normal. If a birthmark grows out of proportion or changes in colour or surface, we recommend bringing it to an examination.
Is the red mark left by a spot also pigmentation?
A red or purple mark is caused by widened blood vessels in healing tissue and is different from a brown pigment mark. A brown mark reflects an increase in pigment, and the two are treated in different ways.
Should I see a dermatologist in Denizli to find out what type of mark I have?
Yes. Telling pigment marks apart, and distinguishing them from moles, is the work of a dermatologist. At our clinic we look at your mark in daylight and with a dermatoscope, identify its type and then discuss monitoring or a treatment plan.
