New Dark Spots After 45: Why They Appear in Menopause — and What Fades Them

They are flat, they are brown, and they were not there before. On the cheekbones and temples, across the chest, on the backs of the hands. Nothing hurts, nothing itches, and that is exactly why most women leave them alone for two years and then start looking for something that works.

The first useful thing to know is that "dark spots" is not one thing. It is three, they respond to different treatment, and telling them apart is most of the job.

The three things people call dark spots

• •Sun spots. Small, flat, tan to dark brown, with a fairly definite edge. They sit where the sun has been over a lifetime: cheekbones, forehead, chest, forearms, the backs of the hands. Each one is a patch of skin that has been quietly overproducing pigment for years.
• •Melasma. Larger, softer-edged patches that come in symmetrical clouds — across both cheeks, the upper lip, the forehead. It is the hormonal one: it flares in pregnancy, with the pill, and for some women with hormone therapy, and it is stubborn in a way sun spots are not. Heat and light both feed it, which is why it comes back every summer.
• •The mark left behind. A brown or grey shadow where a spot, a scratch or a patch of irritation used to be. It is not a stain and it is not permanent — it is pigment the skin made in response to inflammation, and it fades on its own, slowly.

If you cannot tell which you have, treat that as a reason to ask a doctor rather than a reason to guess — melasma in particular gets worse under some of the treatments that clear sun spots.

Why they surface now

Two things converge. The first is arithmetic: pigment damage accumulates and there is simply more of it by fifty than there was at thirty. The second is that the skin holding it has changed — it is thinner, it repairs more slowly, and it inflames more easily than it used to. Skin that inflames easily makes pigment easily, so every spot, every scratch and every reaction to a product that stings now has a decent chance of leaving a mark behind it.

That second half is the part you can still do something about. The first is history.

What actually fades them

• •Sunscreen, every single morning, without exception. This is not the boring preamble to the real answer — it is the answer. Every other treatment on this list is trying to remove pigment while daylight puts more back. Women who use the actives and skip the sunscreen spend a year going nowhere and conclude the actives do not work.
• •Vitamin C in the morning, which interrupts pigment production and works well under sunscreen.
• •Niacinamide, one of the gentlest options there is — it stops finished pigment being handed up to the surface, and it suits reactive skin that flinches at everything else.
• •Azelaic acid, the quiet all-rounder: it works on pigment, on the redness around it, and on breakouts, and it is safe for melasma.
• •A retinoid at night, which speeds up how fast pigmented cells reach the surface and leave. Introduce it carefully on this skin: how to start retinol safely, low and slow.
• •Ask a doctor about the stronger options if six months of the above has not moved it. Prescription creams and in-office treatments exist, they work, and on melasma especially they are worth the appointment rather than a fourth serum.

You do not need all of these. Two, used consistently for three months, will beat five used for three weeks.

What makes them worse

• •Sun, obviously — but also heat. Melasma responds to warmth as well as light, so hot yoga, saunas and a hot stove all count.
• •Picking a spot. Every squeeze buys a mark that lasts months longer than the spot would have.
• •Aggressive scrubs and strong peels on thinning skin. They inflame it, and inflamed skin makes more pigment. It is entirely possible to darken a patch by attacking it.
• •Anything that stings. A product your skin reacts to is a product that is manufacturing tomorrow's mark, however good its ingredient list looks.
• •Fragrance, on skin that has turned reactive. Same reasoning — irritation is the raw material.

The one kind of spot that is not cosmetic

This is the section a page trying to sell you a serum leaves out, so here it is first-hand.

Do not try to fade a spot you have not had looked at. Almost all of these are harmless. Some are not, and the ones that are not can be dealt with easily when they are found early. See a doctor about a spot that:

• •has changed — in size, shape, color or thickness — over weeks or months
• •has an uneven edge or more than one color in it
• •is itching, bleeding, crusting, or has not healed
• •is noticeably different from all your others, even if you cannot say how

That last one has a name among dermatologists — the ugly duckling — and it is the single most useful thing a non-expert can notice. A skin check is ten minutes and it is the only item on this page that is not about how you look.

How long it takes

Three to six months for sun spots, longer for melasma, and the marks left by old breakouts fade on their own timetable regardless of what you put on them. Take a photo in the same light on the first day, because pigment fades too gradually to see in a mirror — and mirrors are where women decide, wrongly, that nothing is happening.

If breakouts are leaving you new marks faster than you can fade the old ones, deal with that end first: menopause acne, and what actually clears it.
