How to get sea salt and chlorine off your skin

In short

Water alone won't shift it: on top of the salt there's sunscreen, sweat and oil, and none of that dissolves in water.
The order that works: rinse with fresh water · lift it with micellar water or a cleansing oil · gentle cleanser for thirty seconds · moisturise while the skin is still damp.
Mineral sunscreen is built not to come off in water. It needs something oily or micellar to lift it.
In this humidity, light textures: gel or gel-cream, not a butter.
Don't exfoliate on a day you caught a lot of sun.

What the sea leaves on your skin

Coastal air leaves a salt film on your skin. It isn't only what sticks to you when you swim: living here means having it on you even on days you never get in. That film dries your skin out, dulls your tone and makes your face look flat.

Pool chlorine does something similar by a different route: it throws the comfort of facial skin off faster than people think, especially if you swim every day.

Why water alone won't shift it

Salt dissolves in water, true — but on top of it you have leftover sunscreen, sweat and oil, which don't. Water runs over the whole lot and leaves it stuck there. That's why you come out of the shower feeling "clean" and an hour later your skin is tight.

The order that works

Rinse with fresh water as soon as you can, the sooner the better. That takes off the sand and drops the salt concentration.
Lift it with something oily or micellar. Sunscreen, mineral especially, is built not to come off in water. You need a micellar water or a cleansing oil to lift it.
Wash with a gentle cleanser. Thirty seconds of massaging, lukewarm water, not hot.
Moisturise while your skin is still damp. In this humidity, keep it light: a gel or gel-cream, not a butter.

Micellar water and a gentle cleanser: the two steps a shower doesn't do.

What not to do

Don't scrub on a day you got a lot of sun. Your skin is already irritated; rubbing it on top only drags the problem out. Once a week is plenty, on a quiet day.
Don't use hot water. It's tempting, and it dries you out more.
Don't sleep in your sunscreen thinking it's "protecting" you. At night there is no sun and there are blocked pores.

The air conditioning bit

If you clean properly but spend twelve hours a day in air conditioning, your skin will still feel tight. Air conditioning dehydrates quietly, and it's the factor almost nobody names. The answer isn't to clean less: it's to put water back at night.

What people ask after the beach

Do I need to bother if I didn't get in the sea?

Yes. Coastal air leaves a salt film on you whether you swim or not. It's why skin looks dull here even in weeks you never touched the water.

Do I rinse micellar water off or leave it on?

After the beach, rinse it. Micellar water lifts the sunscreen and the salt, and leaving it sitting on top of all that is what usually ends in breakouts.

What about hair?

Same principle: rinse as soon as you can, and a gentle shampoo the same day. Dried salt and chlorine keep working on your hair for hours.

How often can you exfoliate living here?

Once a week is enough for most people, and never on a day you caught a lot of sun. This climate already stresses your skin from the outside; scrubbing on top of that just drags the irritation out.
