People who search for how to remove tan from hands have usually noticed the same thing: the face went back to normal weeks ago and the hands did not. The backs of the hands, the forearms and the tops of the feet are often two shades deeper than the upper arm under the sleeve, with a clean line where a watch or a sandal strap sat.
There is nothing unusual about the skin there. Those areas get more sun than anywhere else on the body and almost no protection, and that is why they stay dark.
Why these areas tan the most
They are out all day. A face gets sunscreen on a good morning. Hands hold handlebars and steering wheels, forearms rest on a window ledge, and feet sit in open sandals from March to October.
Car glass does not stop it. Side windows block most of the rays that burn and let through a large share of UVA, the longer wavelength that tans. A daily commute with one arm by the window is enough to tan that arm more than the other.
Sunscreen does not last on hands. Even when it is applied, the first hand wash takes most of it off, and few people put it back.
Skin on the limbs renews more slowly. A tan leaves when the cells carrying the pigment reach the surface and shed. That cycle is quicker on the face than on the arms and legs, so the same tan takes longer to clear lower down. How to fade a tan explains the process.
What fades it
Start with cover, because nothing else works while the tan is being topped up every afternoon.
For a two-wheeler or a long drive, cotton gloves or sun sleeves do more than any cream. They block the light completely and do not wash off. Closed shoes or socks do the same for feet.
Where cover is not practical, use sunscreen on the backs of the hands, the forearms and the tops of the feet, and put it back on after washing. How much sunscreen to apply gives the amounts, and they are larger than most people expect.
Moisturise every day. Dry skin on the hands and shins looks greyer and darker than it is, and a plain lotion changes that the same day. It is the least impressive step and the only quick one.
Exfoliate gently and not often. A body lotion with lactic acid or urea loosens surface cells without scrubbing, and once or twice a week is enough. The gain is small. It brings the pigmented cells to the surface a little sooner and no more than that.
A leave-on product with niacinamide can help the colour come back more evenly over the following months. It slows the handover of pigment to the surface cells, so it works on the next layers of skin and has no effect on the ones already tanned.
Then wait. With the sun kept off, a moderate tan on the arms fades over a few months. Feet and shins are slower.
What makes it worse
Lemon and sugar scrubs are the usual advice for hands. The sugar is friction, and friction on the knuckles thickens and darkens skin. Lemon juice is acidic enough to irritate, and it reacts with sunlight on exactly the skin that sees the most sun. What lemon juice does to skin covers the burn it can leave.
Pumice stones and loofahs used hard on the feet and elbows do the same thing more slowly. Skin answers repeated rubbing by getting thicker and darker, which is the cause of dark knees and elbows.
Bleach lightens the fine hair on the arms and strips the surface. The skin under it is the same colour as before and more irritated.
Creams sold for hand whitening with results in days deserve suspicion. A fast change on thick skin usually means a steroid or another drug is in the tube, and how to tell whether a cream contains a steroid lists the signs.
Can a hand tan be removed for good?
No, and nothing sold for it can change that. A tan is the skin's response to light, and skin that sees the same light again will tan again. The lasting result comes from the cover and the sunscreen. Any product is a small addition to those.
Skin also cannot fade below the colour it has without sun. The inner upper arm is a fair guide to where the hands can return to.
When it is not a tan
A tan is even, sits only where the light reached, and has an edge that follows clothing. Other patterns point elsewhere.
Darkening on the knuckles alone, with the rest of the hand unchanged, can come from friction and also from vitamin B12 deficiency. Dark knuckles explains how to tell and when to ask for a blood test.
Colour that stays put through a whole winter of covered arms, or darkens without any change in sun, is worth a doctor's opinion. Some medicines and some hormonal conditions darken skin, and skin getting darker without sun covers the common ones.
Cham makes no sunscreen, so the step that matters most here has no product of ours attached. The Brightening Body Lotion and the Brightening Face and Body Serum both carry niacinamide and are made for skin below the neck. They belong to the slow part of this, after the cover is sorted.
