How to know it's working

It’s the hardest question in skincare, because the face responds slowly and without much clarity. Here are some usable reference points.

The three signs that mean nothing

The immediate sensation. Skin that feels soft ten minutes after application tells you about the product’s texture, not its effect. The two have nothing to do with each other.

The next-morning result. It depends mostly on your night. A good night gives you a good face no matter what you applied.

The opinion of someone who knows you’ve changed something. They will see a change. It’s mechanical and carries no informational value.

The five signs that matter

One — the day holds up better. Your face at six in the evening looks more like your face at nine in the morning. It’s the most reliable sign of all, and the easiest to observe.

Two — recovery is faster. After a short night or a hard week, it takes two days to return to normal instead of two weeks. This is what you gain first, and it’s what matters most in real life.

Three — you think about it less. You no longer check your reflection in shop windows, you no longer dread certain lighting. The disappearance of a preoccupation is a sign, and a good one.

Four — winter is less different from summer. A routine that suits you narrows the gap between seasons. A routine that doesn’t suit you only works in easy conditions.

Five — you no longer feel like adding anything. The urge to add is the symptom of a perceived lack. When it disappears, something is covered.

How to look properly

In the morning, in daylight, at a normal distance, without a magnifying mirror.

The magnifying mirror shows nothing useful: it shows a reality that no one ever sees, including you, outside of that mirror.

And write something down at the start — two lines are enough. Memory for a face is very poor, and without a written point of comparison, you’ll be unable to say in six weeks what has changed.

The timeline

Don’t draw any conclusions before three weeks. The first useful signal arrives between three and six weeks. Confirmation at three months. What holds at six months holds for real.

If none of the five signs appear

It doesn’t necessarily mean the routine is bad. More often, it means it wasn’t addressed to you.

An excellent product applied to a face that was asking for the opposite does no harm: it does nothing. And a non-result has no shape, which makes it very hard to identify — you put it down to time, to age, to the season.

What settles it is knowing what your face is actually asking for. That can’t be deduced from what you observe, because two opposite logics produce the same signs. It can be read from the beginning.
