Rico move

Scan the product before stacking it. Rico helps you read routine conflicts and decide whether to use it, slow it down, or compare a better-fit option.

Start with the full formula

Compatibility depends on the full formula, strength, frequency, your barrier, and what else is in your routine. The ingredient name alone is not enough. The front label can tell you what the product wants to promise, but the ingredient list shows what your skin actually has to handle. Use the formula to understand the product role, texture clues, active load, fragrance pattern, and whether it makes sense beside the products already in your routine.

Look for the pattern, not one scary ingredient

You add too many strong products, then your skin gets red, dry, or irritated. One ingredient rarely tells the whole story. A product can look good in one app and still be too rich, too active, too fragranced, or too hard to layer for your skin. The better question is whether the full product fits the concern you are shopping for right now.

Choose one calm next move

Scan the product before stacking it. Rico helps you read routine conflicts and decide whether to use it, slow it down, or compare a better-fit option. If the product does not look like a strong match, do not force it because the packaging, reviews, or trend made it feel urgent. Compare a product that does the same routine job with fewer fit concerns.

Use a better-fit swap when the formula feels off

When your routine already has strong actives, a gentler support product may be the smarter swap.
