We’ve all been there. You’re standing in the skincare aisle holding two serums that basically promise the exact same thing. One claims to be “clean", the other is “dermatologist tested", both say they’ll give you glowing skin, and somehow you’re supposed to know which one is actually worth your money. Cute!
As a Master Esthetician, one of the biggest things I’ve learned is that the packaging of a skincare bottle is designed to sell you the product. Because, c'mon who doesn't want their skincare routine to look aesthetically pleasing? When you look at the back of the bottle is when you can actually start figuring out what’s inside all that pretty packaging.
Learning how to read skincare labels can seem intimidating at first, especially when the ingredient list looks like it requires a chemistry degree and a translator to understand. I promise, it really doesn't! Once you know what to look for, understanding skincare ingredients becomes SO much easier. And when you understand your ingredients, you’ll be much better equipped to decide whether a product actually deserves a spot in your routine.
What Does the Ingredient Order on a Label Actually Tell You?
Now let’s flip that bottle around.
In the U.S., cosmetic ingredients are generally listed in descending order of predominance, so the ingredients appearing in higher percentages are listed towards the beginning. Meaning the quantity of the ingredient within the product descends the further down the list you go! Once ingredients start to appear at concentrations of 1% or less, they can be listed in any order after the ingredients above 1%.
But, why does the order on a label even matter? Because, it gives you context!
Something I commonly see with trendy skincare is where we have a hero product that is marketed heavily around a specific ingredient. The packaging usually has eye catching photos, fun color scheme, the ingredient is mentioned three times on the front, and it’s basically the entire product’s personality. Then you flip the bottle over and find that ingredient advertised on the packaging hiding near the veeeerrrrryyy bottom of the ingredient list. Meaning, what? That it's one of the least concentrated ingredients in the product. Gasps everywhere, I know.
Although that doesn’t automatically mean the product is ineffective! Some ingredients are intended to be used at low concentrations! But it does mean that you should look a little deeper before assuming the packaging tells you the whole story.
And something to remember: higher concentration does NOT automatically mean better! Skincare is chemistry, not a competition to see who can fit the most active ingredients into one bottle.
Which Skincare Marketing Claims Actually Matter?
Now for one of my favorite games: Is that actually true or does it just sound official?
Words like “clean,” “natural,” “non toxic,” “medical grade,” and even some “dermatologist tested” language can sound incredibly official on packaging. But depending on the claim, they may not tell you nearly as much about a product’s performance as you think.
This is where having skincare marketing claims explained becomes important! Instead of choosing a product solely because the front says something exciting, look for information that can actually help you evaluate the product itself.
What ingredients are in it? What is the product intended to do? Are there official claims from the company? Is this a good match for my skin type? Will this target skin concerns I am currently struggling with?
Basically, don’t let pretty packaging sweet talk you! Lots of products these days LOOK the part, but looks can sometimes be all they're good for. She may be gorgeous, but we absolutely need to see the resume!
How Do You Find the Active Ingredient and Its Strength?
First, it definitely helps to understand that the word “active” can mean totally different things depending on the product.
For OTC drug products, such as certain acne treatments, sunscreens, and some cosmetics you may see an Active ingredient section on the Drug Facts label. That little section identifies the active ingredient in the product and labels its percentage.
For makeup products, it's not always that simple. A product might highlight the amazing ingredients it contains like niacinamide, vitamin C, peptides, or acids but the exact percentage isn't necessarily going to be listed.
So if you’re wondering how to check active ingredient percentage, you'll want to start by checking the entire package rather than only the ingredient list. Look for a Drug Facts panel when applicable, concentration information on the front or back, and any additional information provided by the manufacturer.
And PLEASE don’t assume a bigger percentage automatically equals a better working product! A well formulated product at an appropriate concentration can be much better for your skin instead of starting with the strongest option you can find and absolutely destroying your barrier in the process.
Your face does not need to lose a fight with your acid serum!
Which Skincare Ingredients Should Not Be Mixed?
Now, this is where things can get messy.
When people search for "skincare ingredients that should not be mixed", they're probably expecting a giant list of combinations that are completely and utterly forbidden. But in reality, concentration, frequency, formulation, skin sensitivity, and the rest of your skincare regimen all come into play.
The biggest concern is often stacking too many potentially irritating products at once.
For example, using a retinoid, exfoliating acids, benzoyl peroxide, and another strong exfoliating treatment in the same weekly regimen could be WAY too much for some skin types. Where as more resistant and resilient skin types may tolerate that routine well! Even if individual products work well for you, be cautious when combining multiple powerful actives. Increasing actives can always increase the likelihood of dryness, redness, peeling, or irritation.
This is especially important to remember when incorporating physical exfoliation, including at-home microdermabrasion. Look at your skincare routine as a WHOLE before adding another exfoliation step!
When introducing my skin to a new product, I always prefer the boring but effective approach: start slow, follow the product directions closely, and pay attention to your skin's reaction. Even if your skin may be used to a certain ingredient, different brands have different product formulations and it's always best to introduce new products slowly so your skin can properly adjust.
Remember that burning, peeling, and looking like a tomato are never signs that your skincare is “working harder".
How Do You Check a Skincare Product Before You Buy It?
Now we get to put our skincare detective hats on.
Before impulse buying another new product, turn the bottle around and actually read it! Start with the ingredient list and look for the ingredients you're buying the product for. Remember, it's placement on the ingredients list will tell you about it's concentration within the product. If it's an OTC drug, you'll want to check the Drug Facts panel to see the active ingredient and percentage.
Then zoom out and think about your current skincare routine. Do you already use an exfoliating acid? Retinoid? Benzoyl peroxide? Physical exfoliation? Adding another active product just because TikTok told you that you NEED it may not always be the move.
I also always recommend checking the directions, warnings, intended use, and packaging before using anything new! If you have sensitive skin like me or a history of reactions to new products, patch testing in a small area before applying is my secret hack to knowing wether my skin will love or hate a product!
And when something sounds too good to be true? Go with your gut and do a little research. Look at the brand’s product information and focus on what the product can actually do, not just the biggest words printed on the box.
The Label Tells a Story, You Just Have to Know How to Read It
Learning how to read skincare labels doesn't have to mean memorizing every ingredient known to mankind. Even as an Esthetician, I’m not standing in the aisle reciting ingredient dictionaries for fun!
It’s just about knowing where to look!
Pay attention to the skincare ingredient list, understand what ingredient order can and can't tell you, look for active ingredients and concentrations, and consider how a new product might fit into your current routine.
Most importantly, don't let marketing make the decision for you! The fanciest bottle or trendiest ingredient doesn't automatically mean it's the best choice for your skin.
Skincare definitely becomes a whole lot less confusing when you stop shopping by the front of the bottle and start understanding what's actually happening on the back. And once you learn how to do that? Good luck getting anything past you in the skincare aisle!
