Advanced User Mode Warning

Expanded customization for experienced skincare users.

Basic Mode limits total active ingredients to 20% to help maintain balanced, beginner-friendly formulations.

Advanced Mode increases the total active ingredient limit to 35%, allowing greater flexibility for users familiar with higher-strength skincare routines and ingredient layering.

Higher active concentrations and complex formulations may increase the likelihood of:

  • Irritation
  • Dryness
  • Redness
  • Peeling
  • Sensitivity
  • Itching
  • Burning or stinging sensations
  • Breakouts or purging
  • Inflammation
  • Allergic reactions
  • Barrier disruption
  • Uneven texture
  • Temporary or permanent discoloration
  • Increased sun sensitivity
  • Other skin conditions or effects not listed
  • Product instability depending on ingredient combinations

More actives do not always produce better results. In many cases, simpler formulations may provide better long-term skin barrier support and overall tolerability.

Before Enabling Advanced Mode

We recommend that you:

  • Understand the ingredients you select
  • Introduce new actives gradually
  • Avoid unnecessary stacking of strong ingredients
  • Perform a patch test before full use
  • Start with lower percentages if unsure

Cosmocost automatically restricts many known incompatible ingredient combinations, but Advanced Mode still requires informed ingredient selection by the customer.

  • Already use active-focused skincare products
