Eight weeks on one serum: what to expect, night by night

Most skincare timelines are written to keep you optimistic until the return window closes. This one is written to tell you when to judge.

A signal peptide does not announce itself. There is no tingle, no flush, nothing that reads as evidence. The absence is the point — but it means the first fortnight can feel like nothing is happening, and a lot of people quit there.

Nights 1 to 7 — comfort

Three to four drops of the Aijaé Peptide Serum to clean, dry skin, before moisturiser. It should absorb in seconds and leave no film. If it sits, you have used too much.

What you should notice is an absence: no sting, no tightness, no flush, no flaking. If you are coming off a retinoid and your barrier is compromised, this week may be the first in a while your skin feels calm.

What you should not expect is visible change. Nothing structural moves in a week.

If you experience irritation in this window, stop. It is uncommon with copper peptide, and it is more likely a reaction to something else in the routine than to the peptide — but a serum that stings is not a serum to persist with.

Weeks 2 to 4 — water

The first real change is hydration, and it shows up indirectly.

Skin that holds water reflects light more evenly. You will probably notice it as your face looking less tired in the morning, or fine lines around the eyes reading softer by the end of the day rather than deeper.

This is also the point where dryness stops masquerading as texture. A good deal of what people read as rough skin is dehydration, and when it resolves the surface looks smoother without anything structural having changed.

Take a photo at the start of week one, in daylight, no makeup. You will not trust your memory later, and daily observation is useless for changes this gradual.

Weeks 4 to 8 — texture

Around week four is where most people first say something has changed, and the usual report is about makeup rather than skin. Foundation sits flatter. It stops settling into the same two places by midday.

The second common observation is about daylight. Bathroom mirrors flatter; daylight does not. Skin that reads smoother in a car window at noon is a more reliable signal than anything you see at night.

This is the window where the routine gets simpler for most people. Two or three products bought to compensate for irritation stop earning their place.

Weeks 8 and beyond — firmness

This is the slow one, and the one worth being most careful about.

Firmness is not a surface quality. It is about how skin holds its shape and recovers, and it changes over months, not weeks. When it does change, it rarely announces itself — people describe it as the jaw reading cleaner, or the face looking less tired at the end of the day.

This is the honest reason the guarantee runs sixty nights rather than thirty. Thirty days is enough to judge comfort and hydration. It is not enough to judge the thing most people bought the serum for, and a thirty-day window would quietly be a window that closes before the evidence arrives.

What not to expect

It will not resurface skin. That is what acids and retinoids do, and if that is your goal you want one of those.

It will not remove deep static lines — the ones present when your face is completely still. Nothing topical does.

It will not work faster if you use more. Three to four drops is the dose; doubling it wastes product.

And it will not do much if used intermittently. A signal repeated nightly is the entire mechanism. Three nights a week is not a smaller version of the result — it is a different, mostly absent one.

How to judge it properly

Photograph at week one and week eight, same light, same time of day, no makeup. Compare those two images and nothing in between.

Ask whether your skin is calmer, whether makeup sits differently, and whether you have stopped reaching for other products. Those three questions are more honest than staring at your face.

Then decide. Sixty nights is long enough to know, and if the answer is no, we would rather refund you than have you persist out of politeness.
