Is 10% Niacinamide Automatically Better Than Glaamorr’s 5%?
A higher percentage alone does not tell you which finished serum is better for you. Glaamorr’s current serum states 5% niacinamide. To compare it fairly with a 10% product, you would need to consider the complete formulas, directions, relevant evidence and your own circumstances—not just rank two numbers.
What one study can tell us
A published 12-week study compared a moisturizer containing 5% niacinamide with its moisturizer control in 50 white women aged 40–60. It reported improvements in several measured appearance outcomes. It did not test Glaamorr, compare 5% with 10%, or establish results for every age or skin tone. Bissett and colleagues, 2004.
That is evidence about a tested formulation and population, not proof that every 5% serum performs identically. Nor can it establish that a higher concentration is necessary.
Compare complete products
Glaamorr’s pack names other ingredients alongside niacinamide. Another brand’s 10% serum may differ in more than concentration. If both formulas change, any difference you notice cannot confidently be attributed to that one number.
Check the full ingredient lists, intended use and warnings. Do not double the amount of a 5% serum to “make it 10%”: using more product does not change the formula’s concentration.
Choose a reason, not a race
Ask what concern you want to address and whether the available information supports your expectations. A comfortable, clearly understood routine is a more useful starting point than automatically buying the highest number.
This guide does not declare Glaamorr superior to a named competitor or promise faster results. It gives you a fairer way to evaluate its 5% serum without turning concentration into a universal quality score.
