Brown patches across the cheeks, forehead or upper lip that were not there two summers ago. Flat spots on the hands and chest. Marks left by spots that used to fade in a fortnight and now take a year. Pigmentation is one of the most visible changes of midlife skin, and it is also one of the most treatable — provided you get the type right and accept that the timeline is months, not weeks.

The three things people lump together

They look similar and are treated differently.

Melasma — symmetrical brown or grey-brown patches, usually on cheeks, forehead, upper lip and jaw. Hormonally influenced, worsened by sun and heat, and prone to returning. Far more common in women, and more common in medium to deeper skin tones.

Sun spots (solar lentigines) — discrete, flat brown spots on the face, hands, chest and shoulders. Accumulated sun exposure, showing up decades later.

Post-inflammatory hyperpigmentation — marks left behind by spots, eczema, or any inflammation. Extremely common in midlife because skin heals more slowly, and it is the main reason midlife acne is so demoralising — see adult acne in perimenopause.

Why the transition makes it worse

  • Melasma is driven partly by estrogen and progesterone, which is why it classically appears in pregnancy and on the combined pill. In perimenopause, fluctuating hormones can trigger or worsen it
  • Heat is an independent trigger, not just light — which means hot flashes may contribute. This is under-appreciated and worth knowing if your melasma flares alongside vasomotor symptoms; see hot flash triggers and relief
  • Cumulative sun damage surfaces now. Most of the spots appearing in your fifties were earned in your twenties
  • Slower cell turnover means pigment clears less efficiently
  • Slower healing means every spot and scratch leaves a longer-lasting mark

The non-negotiable

Nothing else in this article works without it: daily sunscreen, all year, on the face, neck, chest and the backs of the hands.

For pigmentation specifically:

  • SPF 30 minimum, 50 preferable, broad spectrum
  • Reapply if you are outside for extended periods
  • Visible light matters for melasma, not just UV. This is why tinted sunscreens containing iron oxides outperform untinted ones for melasma specifically — a genuinely useful detail that most people are never told
  • Mineral filters (zinc oxide, titanium dioxide) are often better tolerated by sensitive midlife skin

A tinted mineral sunscreen with iron oxides is the single highest-value purchase for this problem. Also useful: a wide-brimmed hat, and shade during the strongest hours.

Treating pigmentation without sun protection is emptying a bath with the tap running.

What has evidence

For melasma and general pigmentation:

  • Azelaic acid — good evidence, well tolerated, and it treats acne and redness at the same time. A sensible first choice for midlife skin
  • Tranexamic acid, topically, with growing evidence for melasma. Oral tranexamic acid is used by specialists in some cases, but it carries clot risk and is not something to source informally — this matters given that menopause and hormone therapy are already part of your clot risk picture; see HRT and blood clot risk
  • Retinoids, which speed cell turnover and help pigment clear, and independently improve texture and fine lines
  • Vitamin C, modest but reasonable, and it pairs well with sunscreen
  • Niacinamide, mild, well tolerated, barrier-supporting
  • Hydroquinone, effective and the traditional benchmark, but it should be used in courses under supervision rather than indefinitely, and its availability differs by country
  • Kojic acid, arbutin, cysteamine — secondary options with some support

Procedures — chemical peels, certain lasers and microneedling — can help, but melasma is notorious for rebounding worse after aggressive treatment, particularly heat-based devices. This is one to do with an experienced practitioner who has seen a lot of melasma, not at a general beauty salon.

What to expect, honestly

  • Three to six months before meaningful change. Pigment sits deeper than most people assume
  • Melasma is managed, not cured. It commonly returns with sun, heat, or hormonal change. That is not a failure of the treatment
  • Sun spots respond better than melasma to procedures
  • Post-inflammatory marks fade on their own, but slowly — sunscreen and a retinoid speed it up
  • Introduce one active at a time. Irritating your skin causes inflammation, and inflammation causes more pigment. The most common self-inflicted setback here is being too aggressive

Does HRT cause or help it?

Melasma is hormonally influenced, so hormone therapy can trigger or worsen it in some women — as the combined pill can.

It is not a common reason to stop treatment, and it is manageable with sun protection and topicals. If melasma appeared or worsened after starting, it is worth raising: the route and the progestogen type can be discussed, and transdermal versus oral may be worth trying. See HRT types and forms and HRT risks and benefits.

Equally, treating hot flashes may help indirectly if heat is one of your triggers.

What needs a doctor, not a serum

This is the part that matters more than the cosmetics. See a clinician about:

  • A mole or spot that is changing in size, shape, or colour
  • Asymmetry, irregular borders, multiple colours, diameter over about 6mm, or any evolution
  • A spot that itches, bleeds, or does not heal
  • A new pigmented streak under a nail
  • A single spot that looks different from all your others

Midlife is when skin cancer risk rises, and "just pigmentation" is a common assumption that occasionally goes badly. If in doubt, get it looked at — see health screening in your 50s.

Also worth checking: sudden widespread darkening, particularly with fatigue and low blood pressure, which has medical causes unrelated to skin, and new pigmentation after starting a medication, since several drugs cause it — see medications that mimic menopause.

The simple version

Tinted mineral sunscreen every day, one active ingredient introduced slowly, three months of patience, and get anything that is changing checked. That is most of what works, and it costs less than one course of a device treatment.
