Aloe, and the nature it was always meant for

There is an aloe on many a windowsill, and there was already one on the windowsills of Mediterranean houses in antiquity. Dioscorides describes it in the first century. Sumerian tablets mention it long before that. It is one of the rare care plants that has always been kept alive within reach rather than dried in a jar — because it is only worth anything fresh.

What it is, before it is an ingredient

The aloe leaf has two layers that must not be confused. Just beneath the green skin runs a yellow latex, bitter, irritating, which is set aside. At the centre lies the parenchyma: a translucent gel, more than ninety-nine percent water, held together by long-chain polysaccharides.

It is these chains that do everything. They hold the water and form, as they dry, a supple, breathable film. The rest — the traces of minerals, enzymes, vitamins — takes up a great deal of room in marketing copy and very little in the leaf.

What it does on a face

It cools and it soothes, immediately, and the effect is real. Aloe gel on skin heated by the sun, by the wind, by a reaction, brings a relief that no cream can imitate — because it is not a cream: it is water held by a mesh that evaporates slowly.

It does not nourish. Aloe alone on dry skin leaves, as it dries, a feeling of tightness, and many people conclude from this that it dries the skin out. It does not dry it out: it simply brings nothing oily, which is not the same thing. On skin that lacks substance, it goes under an oil, never in its place.

The best use remains the simplest. A cut leaf, the gel scraped out with a spoon, applied within the minute. A shop-bought gel is always stabilised, often thickened further, sometimes almost empty.

And yet, it has never suited everyone

The reading of the five natures places aloe opposite Fire — that which rises, that which lights up, that which colours before a word is spoken. The relationship is not one of kinship but of useful opposition: water meets heat.

The face of this nature warms at the forehead, lights up in conversation, takes an hour to settle back down. It marks itself with what it feels. A fresh, light matter is for it the most exact answer there is.

For the other natures, aloe is a pleasant intermediary and nothing more. A fine face seeks substance; a steady face seeks to lighten itself another way; a face that pushes forward seeks to be unburdened, not cooled.

The delicate point

Aloe is the universal rescue remedy, and that use is legitimate: after the sun, after the wind, after a skin upset, it suits everyone because it does almost nothing other than give back water.

But a rescue remedy is not a daily care, and the confusion between the two costs years. What your face asks for every day depends on the nature that is yours — and that nature cannot be deduced from a week of observation. It is read from the very beginning.
