If you have ever faded a dark spot over three months and watched it come back in three weeks, you already know the frustrating part. Treating pigmentation is slow. Causing it takes an afternoon.
This is the long version of why that happens, and what actually changes the outcome. It covers dark spots, tanning, melasma, and early ageing together, because they are four different symptoms of the same cause.
What UV Actually Does to Your Skin
Sunlight reaches you as two kinds of ultraviolet radiation, and they do different damage.
UVB has shorter wavelengths and stops at the outer layers of skin. It is what burns you. It peaks in the middle of the day, and it is much weaker through glass.
UVA has longer wavelengths and goes deeper, into the dermis where collagen and elastin live. It does not burn, so there is no warning signal. It stays roughly constant from morning to evening; it passes through cloud, and it passes through window glass.
That last point is the one most people get wrong. The sun that fades your car seats is reaching your face too, and because it never stings, nothing tells you to move.
Both wavelengths trigger melanocytes — the cells that produce melanin — to make more pigment. That response is protective. Melanin is your skin trying to shield its own DNA. The tan, the spots, and the patches are all evidence that the shielding was needed.
The Four Things People Actually Notice
The fastest visible response. Melanin production ramps up within hours of exposure and darkens the whole exposed area fairly evenly. It fades over weeks — but each cycle of tanning and fading is a cycle of cell damage and repair, and the repair gets less reliable over time.
Dark spots and hyperpigmentation
Localised patches where melanin production has become concentrated and stubborn. They show up most on the face, neck, chest, forearms and the backs of the hands — the areas that get sun every single day without anyone deciding they will.
They also form where skin has been inflamed. A healed pimple, a shaving nick, a scratch — the recovering area produces excess pigment, and UV exposure during healing makes that pigment much darker and much more permanent. This is post-inflammatory hyperpigmentation, and it is the reason dermatologists tell you to keep a healing spot out of the sun.
Larger, symmetrical patches, usually across the cheeks, forehead, and upper lip. Hormones set it up — pregnancy, oral contraceptives, thyroid changes — but UV and heat are what trigger and worsen it. Melasma is notoriously recurrent, and the single biggest factor in whether it stays away is how much UV the skin gets afterwards.
Heat matters here independently of UV, which is worth knowing if you spend time near a stove or in a hot commute.
The slow one. UVA breaking down collagen and elastin over years produces fine lines, loss of firmness, rough texture and a general dullness that no serum reverses quickly. Most of what people call “looking older” on sun-exposed skin is cumulative UVA exposure, not the passage of time. The skin on the inside of your upper arm is the same age as the skin on your face — it just has a different exposure history.
Why India Is a Harder Case Than The Advice Assumes
Most sun protection advice was written for lower-UV climates, and it quietly assumes conditions you do not have.
The UV index is high for most of the year,
not just in summer, and not just in the afternoon. It stays meaningful across far more of the day than in temperate climates.
Heat and humidity break the reapplication model
The instruction is to reapply every two hours. In practice, you are in a meeting, on a scooter, in a metro, or holding a child’s hand across a road. A layer that sits on skin is at the mercy of sweat, wiping, makeup, and time — and by mid-afternoon it is rarely doing what the label promised.
Darker skin tones do not opt out
Higher baseline melanin means more natural protection against burning, but it does not prevent pigmentation. In practice, pigmentation disorders are more visible and more persistent on brown skin, and melasma is more common. The idea that darker skin does not need sun protection is one of the more damaging myths in this category.
What Actually Changes The Outcome
There is a hierarchy here, and most people have it upside down.
1. Cover the skin
A physical barrier does not sweat off, does not need a timer, and does not vary with how thickly you applied it. It is protecting you at hour six exactly as well as at minute one.
2. Seek shade at peak hours
Free, and more effective than anything you can buy.
3. Apply a topical to what is left uncovered
Genuinely useful — for the parts a garment does not reach.
4. Treat the existing damage
Serums and actives work slowly, and only hold their gains if steps 1 to 3 are in place.
Most routines start at step 4 and skip step 1 entirely. That is why the spots come back.
What Sun Protective Clothing Actually Means
Not every garment protects. A regular cotton T-shirt can offer a UPF as low as 5, and wet or stretched fabric performs worse than dry fabric.
UPF — Ultraviolet Protection Factor — is the certified rating for how much UV a fabric lets through. UPF 50+ is the highest rating issued, and it means the fabric transmits under one-fiftieth of the UV hitting it.
The important property is that the rating lives in the fibre. It is not a coating on the surface, so it does not wash out, sweat off, or need reapplying. Wash the garment as often as you like.
Two things about our own numbers, since this is the part brands usually blur:
• The UV Jacket and UV Scarf use UPF 50+ certified fabric and block 98% of UVA and UVB across the area they cover.
• The UV Shield is a lens, not a textile. UPF is a fabric rating and does not apply to it. It blocks 99% of UVA and UVB.
Those figures are deliberately different because they are different materials measured different ways. Anyone quoting one tidy number across a whole range is rounding something.
And the honest limit: covered skin is protected, uncovered skin is not. A jacket protects your arms. It does nothing for your face.
Cover the parts that are out every day. The UV Jacket covers arms, torso, and hands. The UV Scarf covers neck, shoulders, and face when you need it.

The Face Is The Hard Part
Your face gets more cumulative UV than anywhere else on your body, and it is the place you least want to cover. It is also where dark spots, melasma and photoageing show first.
A hat brim helps, but only from directly overhead. Most UV reaching your face is scattered — bouncing off roads, water, glass and pale walls — and it arrives from below and from the sides, where a brim does nothing.
That is the gap the UV Shield is built for: a full-face lens that blocks 99% of UVA and UVB, with a heat-resistant, anti-glare lens you can see through clearly. It is the single highest-value piece of coverage for anyone dealing with facial pigmentation, because it covers the exact area that reacts most and that a topical struggles to hold protection on through a hot day.
Colour and finish options — clear, holographic, mirrored — are in the UV Shields collection.
The face is where it shows first.

Where a Topical Still Fits
We make wearable protection, so it would be convenient to tell you creams do not work. They do.
A broad-spectrum topical is the right tool for skin a garment does not cover — and on most days that includes at least part of your face, your ears and the tops of your feet. Use it there.
What it is not good at is surviving an Indian afternoon unattended. The two-hourly reapplication is not a marketing detail; it is the condition under which the tested protection holds. If you cannot meet that condition — and most people genuinely cannot — the realistic answer is to reduce how much skin depends on it.
Cover what you can. Apply to the rest. That is the whole strategy.
Checking Whether it Actually Went On
Even applied carefully, a topical goes on far less evenly than it feels. The jawline, the ears, the hairline, and the sides of the nose are the usual misses — and those are exactly where pigmentation shows.
The UV Smart Mirror has a UV camera that shows where your SPF actually sits on your skin and where it does not, so you can even it out before you leave. It is a mirror with a camera. It does not block UV, it does not diagnose anything, and it is not a medical device — it just shows you the coverage you thought you had.
Ingredients That Help With Existing Spots
Protection prevents. These treat.
• Vitamin C — antioxidant, gradually evens tone
• Niacinamide — reduces the look of spots, supports the skin barrier
• Retinoids — speed cell turnover; increase sun sensitivity, so night use with daytime protection
• Azelaic acid — well tolerated, useful for post-inflammatory marks and melasma
• Alpha arbutin, kojic acid, tranexamic acid — targeted pigment inhibitors
Give any of these six to eight weeks. And be careful with over-exfoliation: aggressive acids on inflamed skin cause the exact post-inflammatory pigmentation you are trying to clear.
For melasma or pigmentation that is not responding, see a dermatologist. Some of it needs prescription treatment, and guessing costs months.
Four Things That Do Not Work
I only need protection in summer: UVA is roughly constant year-round.
I’m indoors all day: UVA passes through window glass. A desk by a window is meaningful daily exposure.
It’s cloudy: Cloud cover reduces UVB noticeably and UVA much less.
My skin is dark enough: More baseline melanin means less burning, not less pigmentation. Melasma and post-inflammatory hyperpigmentation are more persistent on brown skin, not less.
A Plan That Survives A Real Week
Morning — cleanse, antioxidant serum, moisturiser, broad-spectrum SPF on the face and any skin that will be uncovered. Put on the jacket or scarf before you leave, not after you are already in the sun.
Commuting and outdoors — shield on for the face if you are driving, riding or walking in open sun. Thumb holes over the backs of the hands.
Midday — reapply to uncovered skin if you can. If you cannot, that is the argument for covering more of it.
Night — cleanse, treatment active, moisturiser. Retinoids and acids belong here, never in the morning.
Every day, without exception — the areas that get sun by default: face, ears, neck, chest, forearms, hands.
Frequently Asked Questions
Do dark spots go away on their own?
Post-inflammatory marks often fade over several months if the skin is kept out of the sun. Sun spots and melasma are far more stubborn and generally need both treatment and consistent protection. Continued UV exposure will darken any of them.
Does sun-protective clothing lose its UPF after washing?
No. The rating is a property of the fibre, not a surface coating, so it does not wash out. Our jacket and scarf are machine washable.
What is the difference between UPF and SPF?
SPF rates a topical product against UVB. UPF rates a fabric against both UVA and UVB. They are not interchangeable, and a UPF rating cannot be given to a lens or a shield — those are measured differently.
Do I need sun protection indoors?
If you sit near a window, yes. UVB is largely blocked by glass; UVA is not.
Is a regular jacket enough?
Usually not. Unrated fabric can transmit a great deal of UV, and light or loosely woven cotton performs worst. Rated fabric is tested; an ordinary jacket is a guess.
Can dark skin get sun damage?
Yes. Burning is less likely; pigmentation, melasma, and photoaging are not. Pigmentation disorders are often more visible and more persistent on brown skin.
Where does most facial UV exposure come from?
Daily incidental exposure — commuting, walking, driving, sitting near windows — not beach days. It is the small amounts that accumulate.
The Short Version
Dark spots, tanning, melasma, and early ageing are four faces of one cause. Treating them is slow, and treating them without preventing them is a loop.
The change that breaks the loop is unglamorous: cover more skin, more of the time, with something rated to do it. Then treat what is already there.
Start with whichever part of the day bothers you most. Shields for the face, jackets for the commute, scarves for everything in between.
