active ingredients are those in a product that actually do the work
they’re often acids, or have complex names, but they’re nothing to be afraid of
most commonly, they’re listed first in a product’s ingredient list
Active ingredients are the most important ingredients in a skincare product - they're the specific ingredients that actually do what the product says it does. In short, they're what you're paying for.
However, don't make the mistake of thinking that more active ingredients is better, or if one product has a higher percentage of a particular active ingredient than another it must be better for you. Remember to factor in your own skin type, and the skin concern you're looking to treat. What's great for one person, may not work for another.
