Quick answer: Almost everything that lands on skin falls into one of five groups, and the group decides the method. PVA glue and emulsion paint wash off with water. Waxes, tars and resins dissolve in oil. Inks and lacquers need alcohol. Super glue needs acetone. Dyes, henna and cured plastics dissolve in nothing at all and leave with the dead skin over a few days. Pick what you spilled below.

Search results for this problem are a pile of unrelated kitchen tips, which is why people end up holding acetone against something acetone cannot touch. Chemistry sorts almost everything into five groups, and once you know which group you are in, the method follows. They are listed easiest first.
| Family | What dissolves it | Examples | Typical time |
|---|---|---|---|
| Water-soluble | Warm water and soap | PVA wood glue, school glue, latex and emulsion paint | 1 to 2 minutes |
| Non-polar: waxes, tars, resins | Any oil | Hair removal wax, candle wax, road tar, sticker residue, oil paint | 2 to 20 minutes |
| Alcohol-soluble inks and lacquers | Rubbing alcohol | Permanent marker, tree sap, some spray paints | 5 to 15 minutes |
| Cyanoacrylate glues | Acetone | Super glue, nail glue, lash glue, gel polish | 10 to 15 minutes |
| Nothing dissolves it | Time and skin turnover | Hair dye, beard dye, henna, self-tanner, cured Gorilla Glue, cured epoxy, silicone | 2 days to 2 weeks |
The last family is the one that causes the most wasted effort, and it splits into two very different reasons.
Hair dye, beard dye, henna and self-tanner are not sitting on the surface. Each of them arrives as small colourless molecules that soak into the stratum corneum, the layer of flattened dead cells on top, and only then react into something coloured and much larger. Permanent dye needs peroxide to do it, henna binds to keratin as it oxidises, and self-tanner uses DHA reacting with amino acids in those same dead cells. In every case the colour was created in place, and it is now too big to come back out. That is why no solvent works and why scrubbing only removes skin.
Original Gorilla Glue, mixed epoxy and cured silicone are thermosets: their chains are chemically cross-linked into one continuous network rather than lying alongside each other. Acetone works on super glue because it can get between separate chains. A thermoset has no separate chains, so there is nothing for any solvent to pull apart. The shell is mechanically locked into the surface texture of dead skin, and it leaves when that skin does.
Both cases end the same way: soak, oil, work the edges, moisturise, and let the skin turn over. Two to five days for a cured plastic, two to seven for a dye, and up to two weeks for henna on dry skin.
Nothing on this page goes near an eye. Acetone, alcohol and every commercial remover are all contraindicated on the eyelid and in the eye, where the only correct action is flushing with lukewarm water and getting medical help. Facial skin is thinner than hands and rules out abrasives and alcohol. Hair is the hardest case for any adhesive, because skin sheds and carries the problem away with it while hair does not.
For most substances the wet stage is far easier, and for two of them the difference is enormous. Wet polyurethane wipes off with a dry cloth but sets into something no solvent touches. Hair dye wipes off with plain water before it develops and becomes a several-day problem after. In both cases the useful window is measured in minutes.
Dry, thickened stratum corneum holds more of everything and sheds more slowly, which is why the same spill clears in a day on one person and a week on another. Moisturising is a removal method for the fourth family, not an afterthought.
Not on skin, in any situation: paint thinner, white spirit, turpentine, brake cleaner, petrol, WD-40, oven cleaner, household bleach, or hair colour remover. Several of these cause chemical burns, several are absorbed through skin, and none of them work better than the correct household method. Never use acetone or any solvent near the eyes, and never use acetone on a scalp.
Two more habits cause most of the injuries. Pulling anything that has bonded skin to skin tears the skin instead of breaking the bond, because the bond is stronger than the outer layer. And scrubbing until the skin turns pink means you have stopped removing the substance and started removing yourself, which leaves you with the stain and a damaged barrier that will hold it longer.
There is no universal answer, and that is the actual finding. Five groups cover nearly everything: warm water for PVA glue and emulsion paint, any oil for waxes, tars and resins, rubbing alcohol for inks and lacquers, acetone for cyanoacrylate glues, and nothing at all for dyes, henna and cured plastics, which leave only when the dead skin holding them sheds. Using the wrong group is why people spend an hour on something that would have taken two minutes.
No, and it is the most common mistake. Acetone dissolves cyanoacrylate, which covers super glue, nail glue, lash glue and gel polish. It does almost nothing to wax, tar, hair dye, henna, cured epoxy or original Gorilla Glue. On skin that is already irritated, stripped by waxing or freshly dyed, it strips the barrier without touching the problem and makes the next attempt worse.
Because the colour formed inside the outer layer of your skin rather than landing on it. Dye precursors and henna molecules are small enough to penetrate the stratum corneum, then react there into much larger coloured compounds that cannot travel back out. Self-tanner works the same way. There is no solvent for this, only time: the colour leaves as those dead cells shed, usually in two to seven days and up to two weeks for henna on dry skin.
If you are more than fifteen minutes into a substance from the first four families, the method is wrong rather than insufficient. Acetone on cyanoacrylate works in two to ten minutes of sustained contact. Oil on wax takes about two minutes. Alcohol on marker takes five to ten. Only the last family measures in days, and for that family there is nothing to speed up beyond gentle exfoliation and moisturiser.
Anything in or near the eye or eyelid, anything in the mouth or airway, any burn, any torn or bleeding skin, skin surfaces bonded together that have not separated after twenty minutes of patient soaking, a large area on a child, and any skin that becomes red, itching, swollen, blistered or weeping rather than simply stained or crusted.
