Dark spots, age spots, and freckles all come down to one thing: patches of skin producing more pigment than the areas around them. Most are harmless and cosmetic. What fades them, what prevents them, and what needs a dermatologist are three different questions, and the honest answers are more useful than the marketing ones.
The Main Types of Dark Spots
All of them start in the same place. Melanocytes are the cells that make melanin, the pigment that gives skin its colour. They package it into tiny parcels and hand it off to the surrounding skin cells. When those melanocytes become locally overactive, or when there are simply more of them in one area, pigment builds up and a spot appears.
Where that pigment sits matters more than most people realise. Pigment held in the upper layer of skin fades far more readily than pigment that has dropped into the deeper layer. It is the single best predictor of how patient you will need to be.
Sun spots (solar lentigines)
Flat brown patches on the areas that see the most sun: face, hands, forearms, shoulders. You will also hear them called age spots, brown spots, or liver spots. They are driven by cumulative ultraviolet exposure rather than by age itself, which is why they cluster where the sun hits rather than spreading evenly. They become steadily more common with cumulative sun exposure. DermNet reports they may be found in up to 90% of light-skinned people over the age of 60.
Post-inflammatory hyperpigmentation (PIH)
The flat discoloured marks left behind after the skin has been inflamed or injured. Acne is the most common cause, but eczema, burns, surgery, and cosmetic procedures all do it too. It is extremely common in deeper skin tones: up to 65% of people with darker skin develop PIH after inflammatory acne, and one 2026 review puts that figure as high as 85%.
Two useful things to know. First, PIH held in the upper layer typically settles over 6 to 12 months. Deeper PIH, which looks more blue-grey than brown, improves slowly and can be permanent. Second, the red marks left after acne are a different thing entirely, called post-inflammatory erythema. They are a blood-vessel change, not a pigment change, and nothing aimed at pigment will touch them.
Melasma
Larger, less sharply defined patches, usually across the cheeks, upper lip, forehead, or jawline. It is strongly linked to hormones such as pregnancy, the contraceptive pill, hormonal IUDs and implants, and HRT. It also runs in families. Family history is common, reported in roughly 55% to 64% of patients in some studies, though the figure varies considerably between populations.
One correction worth making, because older skincare articles still repeat it: melasma is not usually temporary. Current dermatology describes it as a chronic, relapsing condition where preventing recurrence matters as much as clearing the pigment in the first place. Up to 30% of pregnancy-related cases are still present ten years later. That is not a reason for despair. It is a reason to expect maintenance rather than a cure.
The ones nobody writes about
A survey of 48,000 adults across 34 countries found that two forms of hyperpigmentation are actually reported more often than melasma: darkening under the arms (17.2%) and around the eyes (14.7%). If your main concern is dark circles, you are in far more company than the internet suggests, and it is a different problem with a different set of answers.
What Causes Them
Ultraviolet exposure is the through-line. It is the primary driver of sun spots, it darkens freckles, it deepens PIH, and it drives melasma relapse. It is the single most important aggravating factor across all of these conditions, though PIH is fundamentally inflammation-driven and can appear on skin that sees very little sun.
But the picture has widened. Visible light, particularly the short-wavelength blue end of the spectrum in ordinary daylight, is now recognised as a clinically significant trigger for melasma, especially in deeper skin tones. That matters practically, because most untinted sunscreens are built around UV protection and give limited defence against visible-light-induced pigmentation. Tinted sunscreens containing iron oxides do better. In a randomised melasma trial, the group using a sunscreen with visible-light protection improved more than the group using a UV-only formula.
Worth being clear about what this does not mean: the evidence points to daylight, not screens. A published report on short-term exposure to blue light from electronic devices found it did not worsen melasma. Current evidence does not show that ordinary screen use causes meaningful hyperpigmentation.
Inflammation is the second major driver. Anything that irritates the skin can leave pigment behind, which is why picking at a blemish reliably makes the mark worse and longer-lasting. Hormones are the third. And some medications cause skin darkening too, though this is where a lot of older articles go wrong: antibiotics and antimalarials can cause a condition called drug-induced pigmentation, which is a separate entity from melasma. The medication most clearly linked to melasma-like facial pigmentation is the anti-seizure drug phenytoin. DermNet reports that around 10% of patients taking it develop pigmentation of the face and neck resembling melasma.
Why They Bother People More Than They "Should"
Dark spots are usually described as purely cosmetic, and clinically that is accurate. It also badly undersells how much they affect people.
The 48,000-person international survey found that half of respondents had at least one pigmentary disorder, that these conditions lasted five years or more in 70% of cases, and that they carried a high self-reported impact on quality of life along with a real sense of social stigma.
The finding I think is most worth knowing: in a systematic review and meta-analysis of 14 studies covering nearly 1,400 people with melasma, clinical severity did not reliably predict distress. Five studies found a significant relationship between severity and quality of life; seven found none. Someone with faint, barely visible pigmentation can be as affected as someone with obvious patches. If your spots bother you more than people around you think they warrant, that is a documented pattern, not an overreaction.
Prevention Comes First
No ingredient and no procedure works as well as not adding more spots in the first place, and none of them hold their results without it.
Daily broad-spectrum SPF 30 or higher is the single most important step. It prevents new sun spots, keeps existing ones from darkening, and protects the results of any treatment you have. Every clinical trial referenced in this article mandated sunscreen use alongside whatever was being tested, which tells you something about how essential it is considered to be.
If melasma is your concern specifically, a tinted mineral sunscreen with iron oxides gives you visible-light protection that a clear sunscreen does not.
What Actually Removes Sun Spots
This is the part most skincare articles skip, so here it is plainly: for an established, sharply defined sun spot, in-office procedures remove pigment far more effectively than any cream does. A 2025 systematic review of 41 clinical trials covering more than 3,200 people found that laser and light-based treatments produced some of the highest reported response rates.
Reported success rates in clinical studies
- Intense pulsed light (IPL): 75-90%
- Picosecond laser: 68-93%
- Q-switched laser: 36-77%
- Cryotherapy (freezing): 37-71%
- Chemical peels: 12-46%
- Fractional CO2 laser: 8-23%
Ranges are wide because they pool many different trials, and the studies did not all define success the same way. Mardani et al., 2025.
The 2026 international expert consensus on hyperpigmentation states that lasers and chemical peels of superficial to medium depth are recommended as first-line treatment for pigment changes resulting from chronic photodamage, and that lasers are more effective than cryotherapy or topical treatments for established, visible sun spots in fair skin types. As with any expert framework, the right choice depends on your diagnosis, your skin tone, and what you are trying to achieve.
A few honest caveats that rarely make it into clinic marketing:
- Picosecond lasers are not clearly better than older Q-switched lasers at clearing pigment. Two head-to-head studies disagree. Where picosecond does appear to win is on side effects. One trial found darkening afterwards in 5% of picosecond-treated spots versus 30% with Q-switched.
- Darkening after treatment is common, not rare. In one 2024 randomised study of 67 sun spots treated with a 532 nm Q-switched Nd:YAG laser, post-inflammatory hyperpigmentation developed in 55.3% of control lesions, compared with 31.0% of lesions treated afterwards with a triple combination cream. Those figures are specific to that laser and that protocol, not to laser treatment in general.
- The wavelengths that work best on pigment carry the most risk in deeper skin tones. Current guidance advises caution with IPL and 532 nm lasers in Fitzpatrick V-VI skin. This is a conversation to have with a practitioner experienced in treating your skin tone, not an afterthought.
- Treatment does not prevent future pigmentation. Without ongoing sun protection, treated areas can repigment and new sun spots keep forming. Every source stresses this.
- Freezing is effective but can leave a pale mark where the spot was, which on the backs of the hands can be as noticeable as the spot itself.
There is genuinely new work here: newer picosecond wavelengths that appear to cause less collateral damage to surrounding skin, and combination protocols pairing a procedure with a topical. But the honest summary is that the field has refined its existing tools rather than discovered a new one. There has been no newly approved drug for sun spots in the last three years; the activity has been in devices.
Where Skincare Fits
Given all that, it would be easy to conclude that creams are pointless. They are not, but their role is specific, and worth being straight about.
Topical skincare earns its place in four ways: preventing new spots from forming, supporting the skin around and after a procedure, maintaining results so pigment does not return, and helping with faint, diffuse unevenness where there is no distinct spot to target. The 2026 expert consensus reaches the same conclusion, describing topical agents as suitable for preparation and sufficient for light or ill-defined spots.
Vitamin C is one of the most widely studied cosmetic ingredients used for uneven pigmentation, and the evidence has a shape worth understanding. The largest controlled dataset, a Bayesian meta-analysis of 31 vehicle-controlled studies in 741 volunteers, found a clear dose-response for preventing UV-induced pigmentation, but no added benefit during the fading phase. In other words, vitamin C's best-evidenced role is protective. That is not a small thing when ultraviolet exposure is the primary driver of sun spots. In the interest of full disclosure, the authors of that analysis were all employees of a cosmetics manufacturer, which is worth knowing even though the underlying studies were vehicle-controlled.
Licorice extract is one of the botanical ingredients used in products aimed at uneven pigmentation. Its own clinical literature is small, so it is worth being precise about what the wider evidence shows: a meta-analysis of 12 randomised trials covering 695 people with melasma found that botanical topical therapies as a category had a favourable tolerability profile, with significantly fewer adverse reactions than harsher comparators and no serious side effects reported. That is a finding about botanicals generally, not about licorice specifically.
Both appear in InviCible Primer+™, developed by Dr. Minas Chrysopoulo, Board-Certified Reconstructive Plastic Surgeon. It combines 17% Stabilized Vitamin C with Licorice Extract as part of the ProBiosyn-4™ complex, in a cream that massages in easily under makeup or sunscreen and is not greasy. It contains no hydroquinone. Since September 2020, over-the-counter skin-lightening products containing hydroquinone cannot legally be marketed in the United States without an FDA-approved new drug application, though it remains available through prescription channels.
Primer+™ is formulated with 17% Stabilized Vitamin C and Licorice Extract to support a brighter, more even-looking complexion and help reduce the visible appearance of discolouration. It is not a substitute for a laser on an established sun spot, and anyone telling you otherwise is selling. It was formulated with sensitive skin and everyday tolerability in mind. It should not be applied to open wounds.
When to See a Professional
Most dark spots are entirely benign. But this is the section to read twice, because the stakes are asymmetric.
See a board-certified dermatologist if a spot changes in size, shape, or colour, has irregular borders, itches or bleeds, or simply looks different from your other spots. The American Academy of Dermatology is blunt about why: what looks like an age spot can be a skin cancer, and using a fading treatment on one gives it time to grow.
This applies with particular force before any cosmetic procedure. A laser can destroy the visible pigment of a spot while leaving behind something that needed a biopsy, and in doing so remove the very visual cue that would have prompted one. Different things can also exist within the same spot. Have pigmented lesions assessed before they are treated, not after.
Sun spots are also a visible marker of cumulative ultraviolet damage. They are retained as one of the predictors in a validated melanoma risk model, and a case-control study found that a heavy count of solar lentigines on the arm was strongly associated with lentigo maligna melanoma. Their presence is a reasonable prompt for a full skin check, whatever you decide to do about their appearance.
A Routine for a More Even Look
- Get anything unusual checked first. Before starting any fading routine, have a dermatologist look at spots that are new, changing, irregular, or different from the rest. This takes one appointment and it comes before everything else.
- Cleanse gently. Morning and night, with a mild cleanser and lukewarm water. Aggressive scrubbing causes inflammation, and inflammation causes pigment.
- Apply Vitamin C in the morning. Smooth a pea-sized amount of Primer+™ over clean skin for antioxidant support and a more even-looking base under makeup.
- Protect with SPF every single day. Broad-spectrum SPF 30 or higher, reapplied when you are outdoors. If melasma is your concern, choose a tinted mineral sunscreen with iron oxides for visible-light protection.
- Leave marks alone while they heal. Picking a blemish extends the inflammation that creates the mark in the first place. This is the cheapest and most-ignored step here.
- Stay consistent, and give it months. Topical results are gradual. If your spots are sharply defined and long-standing, talk to a dermatologist about a procedure and use your routine to protect and maintain the result.
Frequently Asked Questions
What is the difference between age spots and freckles?
Age spots, known medically as solar lentigines, are flat brown patches on sun-exposed skin that tend to persist without treatment. Freckles are usually smaller and genetic, and they often darken with sun exposure and fade in winter. Both are driven by melanin, but freckles come and go while sun spots accumulate.
What actually removes sun spots?
For established, clearly defined sun spots, in-office procedures are the most effective option. A 2025 systematic review of 41 clinical trials found intense pulsed light and pigment-specific lasers had the highest reported success rates, ahead of freezing and chemical peels. Creams work more slowly and are best suited to prevention, faint unevenness, and maintaining results afterwards.
Can dark spots be faded with skincare alone?
Their appearance can be visibly softened over time with daily sun protection and ingredients such as Vitamin C and licorice extract. Change is gradual, unfolding over months rather than days, and faint or diffuse discolouration responds better than a sharply defined spot. Sun protection is what makes any of it hold.
Does blue light from screens cause dark spots?
Visible light in ordinary daylight is now recognised as a trigger for melasma, particularly in deeper skin tones, which is why tinted sunscreens with iron oxides are recommended for it. The evidence for screens is a different matter. A published report on short-term blue light from electronic devices found it did not worsen melasma, and current evidence does not show that ordinary screen use causes meaningful hyperpigmentation.
When should I see a doctor about a spot?
See a board-certified dermatologist if a spot changes in size, shape or colour, has irregular borders, itches or bleeds, or looks different from your other spots. Have any pigmented lesion assessed before it is treated cosmetically, because a procedure can remove the visible pigment while leaving something that needed a closer look.
