Decoding Skincare: How to Understand What’s Really in Your Beauty Products
Published September 9, 2024
In the ever-expanding world of skincare, choosing the right products can be overwhelming. With countless options making bold claims and a dizzying array of ingredients listed on labels, it's easy to feel lost. But understanding what’s actually in your skincare products is crucial for making informed choices that truly benefit your skin. This blog series is designed to help you navigate these complexities by breaking down ingredient lists, starting with products I have used, then broadening to other popular items on the market.
But why is it so important to know what’s in your skincare? For one, it enables you to make decisions based on your unique skin needs rather than marketing hype. It also helps you evaluate whether the extra money spent on luxury brands is justified, especially if drugstore alternatives contain similar key ingredients. Are you really paying for better results, or just for a more prestigious label?
Rethinking the "First Five" Rule: Is It Misleading?
One common method people use to assess skincare products is the "First Five" rule. This rule suggests that the first five ingredients listed on a product label are the most important, as they make up the bulk of the product. However, this approach oversimplifies the science behind skincare formulations. While it’s true that ingredients are listed in descending order of concentration, many active ingredients—like retinol, peptides, or botanical extracts—can be effective even at concentrations below 1%, and therefore might appear further down the list. Dismissing these ingredients simply because they don’t make the “top five” can mean overlooking a product’s potential benefits. Those first five ingredients in a cream often just determine its base or texture, while the truly effective elements, like antioxidants or peptides, appear further down the list. So, while the "First Five" rule can be a helpful guideline, it’s important to understand its limitations and exceptions.
Decoding the INCI List: What Do All Those Scientific Names Mean? If you’ve ever glanced at a skincare product label and felt overwhelmed by the unfamiliar names, you’re not alone. The International Nomenclature of Cosmetic Ingredients (INCI) system is a standardized system used worldwide to name ingredients consistently, regardless of the product’s country of origin. This standardized naming convention has been around since the 1970s and is used globally to ensure consistency across different countries. While it might be daunting to see names like “tocopheryl acetate” instead of “vitamin E,” this system is actually designed to reduce confusion and ensure transparency.
The INCI system requires ingredients to be listed in order of their concentration, from highest to lowest. Ingredients at or below concentrations of 1% can be listed in any order. This structure helps to demystify what’s actually in the products, but it doesn't tell the whole story. For example, water or aloe, which makes up a significant portion of many skincare products (70–95%), is often listed first. The next few ingredients, typically included at 3–5% concentrations, form the product’s core structure. However, beyond these, you might find highly potent ingredients that deliver the promised benefits, even if they’re included in smaller amounts. For example, preservatives, which are often used in tiny amounts, are essential for preventing microbial growth and maintaining the product’s integrity.
Why Ingredient Concentration Matters, but Isn’t Everything While percentages provide some insight, an ingredient doesn't need to be in the top five to work wonders for your skin. Skincare formulations involve careful consideration, including the safety, performance, and clinical testing results provided by ingredient suppliers. Often, active ingredients are formulated at specific levels to balance safety with maximum efficacy, even if they appear lower on the list. For instance, ingredients like retinol are known to be effective at concentrations as low as 0.1%, whereas others, like niacinamide, can be beneficial at a range of concentrations from 2% to 5%. Moreover, the formulation’s pH, the stability of the active ingredients, and the delivery system used to transport these ingredients into your skin all play significant roles in determining how well a product works.
