Why Your Dark Spots Got Worse After 40

(It’s Not Just the Sun)

By Mandy Spence, PA-C | Aura Aesthetics & Wellness, Greenville, SC

You have been wearing SPF. You have tried the vitamin C serums. You have done the facials.

And yet…the dark spots are still there. Or they are getting darker. Or they showed up in places you do not even spend time in the sun.

Here is what most people are never told: pigmentation after 40 is rarely just a sun damage problem. Hormones play a significant role, and until you understand that connection, you can treat the surface all you want and still not get the results you are after.

Your skin and your hormones are more connected than you think

Estrogen influences melanin production, which is the pigment that gives your skin and dark spots their color. When estrogen levels are stable, melanin production tends to stay regulated. When estrogen starts to fluctuate, as it does in perimenopause, that regulation breaks down.

According to the Menopause Society, changes in estrogen during the perimenopausal transition have documented effects on skin pigmentation, barrier function, and collagen production, not just the dryness and thinning most women hear about.

The result? Uneven pigmentation. Spots that seem to come out of nowhere. Existing spots that suddenly look darker. Patches across the cheeks, upper lip, or forehead (classic melasma territory) that were not there a few years ago.

This is why so many women notice a shift in their skin in their 40s and early 50s that does not quite match what they remember about sun damage. It is not all in your head. It is hormonal.

Melasma vs. sun damage: they are not the same thing

Both show up as discoloration. Both can get worse in the sun. But they have different root causes — which means they respond differently to treatment.

Sun damage (solar lentigines)

Results from years of UV exposure. The spots tend to be well-defined, flat, and scattered — especially on the hands, chest, and face. They respond well to targeted laser treatments and resurfacing when properly assessed.

Melasma

Hormonally driven and UV-triggered. It tends to appear in larger, blotchy patches, usually symmetrically across the face. It is far more common in women, and it is closely tied to estrogen — which is why it often appears during pregnancy, while on hormonal contraceptives, or during perimenopause. The American Academy of Dermatology notes that melasma is one of the most challenging skin conditions to treat precisely because of its hormonal component.

Treating melasma the same way you treat sun spots will get you limited results. The inflammation from aggressive treatments can actually make melasma worse — a phenomenon called post-inflammatory hyperpigmentation.

Why topicals alone plateau

Brightening serums, retinoids, and over-the-counter products absolutely have a place in a good skincare routine. But they work at the surface level. If the hormonal signal driving melanin overproduction is still active underneath, you are fighting upstream.

This is the wall most women hit: they do everything right, they see a little improvement, and then it stops. The issue is not the product — it is that they are addressing the symptom without addressing what is causing it.

What actually helps

Effective pigmentation treatment at this stage typically involves a combination of approaches:

• Addressing the hormonal piece. If you are in perimenopause and your hormones are fluctuating, that is worth evaluating. Hormone balance does not just affect how your skin looks — it affects how well any aesthetic treatment works and how long the results last.
• Targeted in-office treatments. Depending on whether you are dealing with sun damage, melasma, or a combination, the right treatment changes. Laser treatments, chemical peels, and medical-grade resurfacing can significantly reduce pigmentation — but the approach needs to be matched to the type of pigmentation you have. Getting this wrong can cause a flare-up rather than improvement, especially with melasma.
• A plan, not a one-off appointment. Pigmentation is one of the most stubborn skin concerns to treat because it requires consistency. A single peel or one laser session will get you some results, but a coordinated plan — the right sequence of treatments, the right at-home maintenance, and attention to what is driving it hormonally — is what produces lasting change. At Aura Aesthetics & Wellness in Greenville, SC, we build that plan with you in the consultation.

What I see in practice

Women who have tried multiple products, maybe a facial or two, sometimes even a laser treatment somewhere else, and are frustrated because nothing has really moved the needle.

The missing piece is usually one of two things: they do not know which type of pigmentation they are dealing with, or no one has connected their skin to what is happening hormonally. When we address both, results look very different.

You are not being vain. You are being proactive. The skin changes you are noticing after 40 are real and they are not a failure of effort. They are a signal that the approach needs to change.

The takeaway

If your dark spots are getting worse despite doing everything right, it is a signal that the surface-level approach is not getting to the root of it.

Pigmentation at this stage of life is a whole-body conversation: skin, hormones, and a treatment plan that understands the difference.

If you are ready to stop guessing and start with a real plan, I would love to sit down with you.

Other Frequently Asked Questions

Why are my dark spots getting worse after 40?

After 40, estrogen levels begin to fluctuate during perimenopause. Estrogen regulates melanin production — the pigment responsible for skin color and dark spots. When estrogen becomes unstable, melanin production can become irregular, leading to new dark spots or existing ones getting darker, even in areas that are not heavily sun-exposed.

What is the difference between melasma and sun spots?

Sun spots are caused by cumulative UV exposure and tend to be well-defined, flat spots on the hands, chest, and face. Melasma is hormonally driven and UV-triggered, appearing as larger, blotchy patches — often symmetrically across the cheeks, upper lip, or forehead. They require different treatment approaches. Treating melasma like sun spots can trigger a flare-up.

Can perimenopause cause dark spots on my face?

Yes. Perimenopause causes estrogen fluctuations that can trigger or worsen facial pigmentation, including melasma. Many women notice new skin discoloration or worsening of existing spots during this time — even with consistent sun protection. This is a hormonal skin issue, not just a skincare issue.

Why is my brightening serum not working on my dark spots?

Topical brightening products work at the surface level. If the underlying hormonal signal driving melanin overproduction is still active, you are addressing the symptom without the cause. Most women hit a plateau because the root issue — hormonal fluctuation — has not been evaluated.

What treatments work best for hormonal dark spots and melasma?

Effective treatment combines three things: evaluating and addressing the hormonal component, targeted in-office treatments matched to your specific type of pigmentation, and a consistent plan with proper at-home maintenance. A single treatment rarely produces lasting results. A coordinated plan does.
