Hyperpigmentation Not Fading? 7 Reasons Your Routine Has Stalled

Reviewed by Skintique's skincare experts · Updated July 2026

If you have been running a brightening routine for months and the marks look much the same, the culprit usually is not a bad serum. It is that something else in the picture is working against you. Most often, the mark you are treating simply is not the kind your routine suits. Pigmentation is one of the few skincare concerns where the diagnosis matters more than the shopping list, because two patches that look near-identical in the mirror can behave completely differently over six months.

This guide is about diagnosis and troubleshooting, not product selection. If you have already worked out what you are dealing with and want help choosing a formula, our buyer's guide to products for hyperpigmentation covers that ground properly. What follows is the other half of the job: why routines stall, and what to change.

Are you actually looking at pigment?

The single most common wasted effort is treating a red mark with a brightening routine. After a spot clears, two different things can be left behind. Post-inflammatory hyperpigmentation is brown, tan or grey-brown and is a melanin problem. Post-inflammatory erythema is pink, red or purple and is a blood-vessel problem. The mark is dilated capillaries, not pigment. A working group of pigmentary specialists writing in American Journal of Clinical Dermatology noted that post-inflammatory hyperpigmentation is more common in darker skin tones and post-inflammatory erythema in lighter ones, though both occur across all skin tones.

There is a simple test. Press firmly on the mark with a clean fingertip, or stretch the skin either side of it, and watch what happens. Red marks blanch. The colour largely disappears under pressure and floods back when you let go. Brown pigment does not; it sits there unchanged. If your marks blanch, no amount of vitamin C, arbutin or kojic acid will shift them, because there is no excess melanin to influence. That is a different conversation, and our guide to preventing and treating acne scars is the better starting point.

2. The colour and the edge tell you how much a cream can do

This is the part almost no article explains, and it is the reason so many people conclude that "nothing works". Excess melanin can sit at different levels in the skin, and dermatology classifies pigmentation accordingly: epidermal, dermal or mixed. It is a distinction with real consequences. Reviewing disorders of hyperpigmentation in the Journal of the American Academy of Dermatology, Wang and colleagues describe how the depth at which melanin sits, whether epidermal, dermal or mixed, shapes both the clinical appearance of a mark and how it behaves.

You can make an educated guess at home. According to DermNet's clinical description of melasma, epidermal pigmentation tends to have a well-defined border and a distinctly dark brown colour, and typically responds well. Dermal pigmentation tends to be ill-defined at the edges and light brown to blue-grey, and typically responds poorly. Mixed patterns, a bit of both, are the most common, and usually show partial improvement. DermNet describes dermal pigment as giving a characteristic grey-purple-brown hue.

So: sharply outlined, chocolate brown, gets more obvious in bright light? Good news, that is the responsive kind. Hazy edges, a smoky or bluish cast, oddly flat in appearance? A topical routine can still improve how the surrounding skin looks, but expect a slower and more partial result, and be sceptical of anything promising to erase it. This is not a failure of your products. It is where the pigment happens to be sitting.

Are you protecting against UV but not visible light?

Almost everyone with pigmentation has been told to wear SPF. Far fewer have been told that a standard broad-spectrum sunscreen is only doing part of the job. Visible light, the ordinary daylight you can see, is itself a pigmentation trigger, and conventional sunscreens do not filter it.

The evidence here is unusually clear. In a 2021 Journal of the American Academy of Dermatology review of tinted sunscreens, Lyons and colleagues set out the mechanism: visible light can induce redness in lighter skin and pigmentation in darker skin; broad-spectrum sunscreens protect against ultraviolet but not adequately against visible light; and for a sunscreen to block visible light, it has to be visible on the skin. Zinc oxide and titanium dioxide are used at nanoparticle size precisely so they do not leave a white cast, which is also why they do not shield against visible light. Tinted formulas containing iron oxides and pigmentary titanium dioxide do. The authors concluded that tinted sunscreens are of benefit to people with pigmentation concerns.

If your dark spots have plateaued despite diligent SPF use, switching from a clear formula to a tinted one is the highest-value single change available to you. Look for iron oxides (often listed as CI 77491, CI 77492, CI 77499) on the ingredient list. Skintique's tinted Heliocare sunscreens and the wider sunscreen range include shaded options, and our broad spectrum sunscreen buyer's guide compares finishes and textures in detail. One caveat worth knowing: UVA passes through ordinary window glass, so a desk by a window or a long drive still counts as exposure.

4. You escalated when you should have steadied

The intuitive response to a stalled routine is to go harder: a stronger retinol, more frequent acids, a course of aggressive peels. With pigmentation this is the classic own goal, because inflammation is one of the things that generates pigment in the first place. Post-inflammatory hyperpigmentation follows injury or irritation of the skin, and DermNet is blunt about the risk with procedures: peels, lasers and IPL may help epidermal pigmentation but can also aggravate it by injuring the skin, and are not effective against dermal pigmentation at all.

In practice this means visible redness, stinging, flaking or tightness is not a sign that a pigmentation routine is working. It is a sign to ease off. If your skin is reactive, a slower approach is genuinely more likely to get you there: gentler exfoliating acids such as PHAs, which are better tolerated than glycolic acid, and a well-supported barrier underneath everything. Our guides to the skin barrier and choosing between AHAs and BHAs are worth reading before you increase anything.

Are you pulling one lever when there are three?

A routine that has been running on vitamin C alone for six months is not a failed routine, it is an incomplete one. There are three distinct jobs, and most stalled routines are doing one or two of them well and one badly:

• Protect. Daily sunscreen, tinted where possible, all year round. Without it, the other two are working against a tide.
• Interrupt. Ingredients that influence melanin formation. Vitamin C, alpha arbutin, kojic acid, liquorice root, niacinamide and tranexamic acid all sit here, and they do not all work the same way.
• Lift. Encouraging turnover of already-pigmented cells, via retinoids or exfoliating acids.

If you have been faithful to one family for months without change, the useful move is sideways, not upwards. Someone who has only ever tried vitamin C has options they have not touched: the tranexamic acid range, azelaic acid, a good choice where marks sit alongside congestion and skin is easily provoked, or the broader discolouration collection. Introduce one new active at a time so you can tell what did what.

Is the trigger still running?

Some pigmentation is not stalling; it is being topped up faster than it fades. DermNet lists the factors implicated in melasma specifically: family history, with around 60% of people reporting affected relatives; sun exposure, including visible light; hormones, where pregnancy, oestrogen or progesterone contraception, coils, implants and HRT are implicated in about a quarter of affected women, and thyroid disorders are associated too; and certain medications and scented products, which can provoke a phototoxic reaction.

That last one catches people out. A perfumed soap, toiletry or cosmetic worn in the sun can be part of the picture, and it is a cheap thing to rule out. Heat exposure is also worth watching if your patches flare in summer, saunas or hot workouts. Our guide to skincare during a heatwave covers the practical adjustments. And if a hormonal driver is still active, the honest expectation is maintenance rather than resolution until that changes.

7. You are measuring progress in the mirror

Pigmentation fades too slowly to perceive day to day, and bathroom lighting varies enough to fake both improvement and relapse. Take a photograph on day one, same window, same time of day, no makeup, no flash, then take one once a month, and only compare month one to month four. Almost everyone who says "nothing is happening" has never done this and is comparing today's face to a memory. Give a genuine change at least twelve weeks before you judge it, and expect longer for the marks that were slowest to appear.

When is it not a skincare question?

Some things belong with a clinician rather than a routine. Any pigmented spot that is changing in size, shape or colour, has an irregular border or more than one colour, itches or bleeds should be looked at by a GP. That is not a cosmetic question, and it is not one to research online. Pigmentation that appeared suddenly, follows starting a new medication, or has that ill-defined blue-grey character also merits a professional opinion, because prescription options and in-clinic procedures sit outside what any cosmetic product can offer. Prescription-strength lightening agents are not available over the counter in the UK for good reason: used unsupervised and long term, they carry their own risk of a stubborn discolouration.

If you are unsure which of the seven scenarios above describes your skin, that is exactly the sort of thing worth a second opinion. You can book a virtual consultation and talk it through before you buy anything else.

The short version

Press the mark and see if it blanches. Look at its edge and its colour to set a realistic expectation. Switch to a tinted sunscreen. Stop escalating and let irritation settle. Add a different family of active rather than a stronger version of the same one. Rule out a trigger that is still running. Then photograph it monthly and give it three months. Most stalled pigmentation routines fix themselves on one of those seven points, and the ones that do not are usually telling you the answer was never going to come out of a bottle.
