More Isn’t Always Better: The Science of Optimal Active Concentrations

More Isn’t Always Better: The Science of Optimal Active Concentrations

One of the biggest misconceptions in skincare formulation is the belief that more is always better. Consumers are bombarded with marketing that boasts 10% niacinamide, 20% vitamin C, or max-strength retinol, but in cosmetic chemistry, efficacy and safety often live in moderation.

Why Less Can Be More

Actives like niacinamide, retinol, and even alpha hydroxy acids (AHAs) are powerful tools in a formulator’s toolbox. But these ingredients have clinical thresholds, beyond which benefits plateau and adverse effects rise. For example:

  • Niacinamide shows proven benefits at just 2% to 5%, including improved skin barrier function and reduced inflammation. At 10%, irritation becomes more common, especially for sensitive skin.
  • Retinol is effective between 0.25% and 1%. At higher levels, it often causes peeling, redness, and long-term skin barrier damage unless properly encapsulated.
  • Vitamin C (L-ascorbic acid) works optimally at 10%-20%. Beyond that, it degrades rapidly, especially in aqueous solutions, and can oxidize on the skin, leading to irritation or discoloration.

Formulators must balance performance, safety, and stability. Pushing actives past their optimal range doesn’t just waste money—it can jeopardize the product’s integrity.

How CM Studio Helps

With CM Studio+, this balancing act becomes significantly easier. The platform’s AI-powered formulator analyzes each ingredient’s effective range based on peer-reviewed studies, supplier documentation, and real-world usage. When building a formula, the system alerts you if an ingredient is outside its proven efficacy zone or raises safety concerns.

Additionally, CM Studio+ includes a built-in compliance tool that flags overuse of restricted ingredients based on global regulations (EU, ASEAN, FDA, etc.), helping brands stay ahead of costly reformulations.

Instead of relying on anecdotal knowledge or outdated Excel sheets, CM Studio gives formulators real-time data to make informed, safe, and effective choices.
