Project Pan: The Skincare Trend That Saves Your Skin (and Money)

Project pan is simple: use products until you can see the bottom, before buying replacements. It began as a spending discipline on the internet and turned out to be a skincare one, because the most common reason a routine underperforms is that it changes too often.

Why it works on skin, not just budgets

Most actives need eight to twelve weeks to show what they can do. Pigmentation takes longer. A routine that gains a new serum every fortnight never gives anything long enough to be judged, and it makes reactions impossible to attribute — when four things are new, you cannot know which one stung.

Finishing a product does three things: it produces a real verdict, it exposes the steps you never actually reach for, and it stops you paying a premium for novelty.

Running one properly

• Pick five to eight products you genuinely use, including one cleanser, one moisturiser and your SPF.
• Set an end point, not a deadline: empty, or a fixed date if a product is clearly not working.
• Keep a two-line note per product — how your skin looks, whether you reach for it willingly.
• Allow one exception. If something stings, stop. Discipline is not a reason to keep irritating your face.

What tends to survive the pan

• Cleansers, which get used regardless.
• A moisturiser you like the feel of.
• One retinoid, one vitamin C or one acid — rarely all three.

What usually does not: essences bought for a texture, masks bought for a photograph, and the third serum in a stack that was doing the same job as the first.

The buying rule that comes after

Once you have panned a shelf, replace like for like only when you have a reason. "I finished it and my skin was better" is a reason. "There is a new formulation with a new peptide" is marketing. Two of our verdict pieces are useful ballast here: is collagen worth it and is vitamin C worth it.

Cosmetic information only. Do not push through a product that burns, itches or triggers breakouts in the name of finishing it.
