Reading an ingredient list like a formulator

An ingredient list tells you what is inside. It rarely tells you why. The why is concentration — the difference between a headline ingredient sprinkled for marketing and one dosed to move the needle.

Take niacinamide. Below 2%, it is a nice-to-have. At 5%, where LUCORE sits, it visibly refines pores and supports the moisture barrier without the flushing some feel at 10%. Tranexamic acid follows the same logic: under 3% is where dermatology research finds the sweet spot for tone without irritation.

Peptides work differently — they are signals, not sledgehammers, effective in fractions of a percent. Matrixyl 3000 and copper tripeptide-1 need parts per thousand, not per hundred.

When you read a label, look for the actives you recognise, then ask the only question that matters: is there enough of it to do what the front of the bottle promises?
