Most beauty content tells you what to buy — “Top 5 Moisturizers,” “5 Serums You Need Right Now.” But when I’m consulting with clients in the treatment room, what I really want to teach them isn’t which product to grab — it’s how to judge a product.
Products change constantly, and trends cycle every year. But once you learn how to choose skincare products, that skill stays with you for life. So today I’m laying out what I actually check, as an esthetician, before deciding whether a new product is worth buying. This isn’t a list of recommendations — it’s a set of criteria.
1. What problem is this product actually trying to solve?
Before I even pick up a product, I always ask myself first — “What am I actually trying to address right now?” Dehydration? Acne and breakouts? Pigmentation and dark spots? A damaged barrier? Firmness and wrinkles? Once the problem is clear, the product choice becomes clear too.
On the other hand, if you buy something just because “it’s trending” or “everyone’s using it,” you end up with a product your skin doesn’t actually need right now. Problem first, product second.
2. What’s the key ingredient?

You don’t need to memorize the entire ingredient list. There’s really only one thing I’m looking for — what this product was designed to do. In other words, does the product’s key ingredient match the concern I identified in step 1? If hydration is the goal, I look for humectants like hyaluronic acid and glycerin as key ingredients. If it’s soothing, I look for Centella Asiatica (cica) and panthenol. If it’s brightening, I look for vitamin C or niacinamide.
And I try not to fixate too hard on any one “hero ingredient.” How a product actually feels and performs comes down to the full formula — the texture, the moisturizing agents, the emollients working together — not a single ingredient in isolation.
(If some of these ingredient names are unfamiliar, my ingredient breakdowns can help — for example essence vs. serum vs. ampoule or retinol vs. retinal.)
3. Where does that ingredient sit on the ingredient list?

Here’s a useful tip. Cosmetic ingredients are generally listed in descending order of concentration. So if the key ingredient appears near the top, there’s a decent chance it’s present in a meaningful amount.
That said, the exact labeling rules can vary by country and regulation. Ingredients are generally listed from highest to lowest concentration, but ingredients below a certain threshold can be listed in any order, so position on the list alone isn’t a reliable way to judge exact concentration.
And one more thing — an ingredient being near the top of the list doesn’t automatically mean the product is more effective. Different ingredients require different effective concentrations, and formulation and stability also affect real-world performance and how a product actually feels on skin.
So I don’t just take a front-label claim like “10% niacinamide!” at face value. I look at where the key ingredient sits on the ingredient list, and — just as importantly — whether the whole formula is actually built around my concern.
On top of that, I don’t get swayed by big-number marketing claims like “10% niacinamide” or “100,000 ppm peptides.” Different ingredients have different appropriate use concentrations and different potential for irritation, and effectiveness isn’t determined by concentration alone. This matters especially for ingredients with irritation potential, like retinoids or exfoliating acids — “higher concentration” doesn’t automatically mean “higher efficacy” for your skin. A high number on the label can actually be too much for your skin to handle.
4. Do I actually need this ingredient?

This is the part people miss most often, surprisingly. If your routine already includes vitamin C, niacinamide, AHA/BHA, and a retinoid, do you really need to add yet another active?
Stacking actives without thinking it through doesn’t double your results — it usually just increases irritation and drains your wallet. So I always ask whether a new product is filling a gap that’s actually missing from my routine, or just duplicating something I already have.
5. What Is the Irritation Risk?
This matters even more if your skin tends to be sensitive.
- Fragrance — fragrance itself isn’t a problem for everyone, but if your skin is sensitive or already irritated, it’s worth being cautious with fragranced products.
- Exfoliating acids (AHA/BHA) and strong retinoids — great ingredients, but depending on your skin’s current state, they can be too much.
- Multiple actives in one product — check whether a single product is stacking several potentially irritating ingredients at once.
And for any new product — especially ones with fragrance, acids (AHA/BHA), or retinoids that carry irritation potential — it’s smart to patch-test on a small area first before applying it all over your face. (That said, a product that passes a small-area patch test can still cause irritation or an allergic reaction when used more broadly.) And if your skin is already sensitized, adding a new active isn’t the priority — soothing and recovery come first. See my barrier repair guide for more on that.
6. Does the texture actually work for my skin?
Texture matters just as much as ingredients. In my experience working with clients, this is where a lot of people go wrong.
- If you have dry skin and only reach for very light, gel-based textures → you may end up feeling under-moisturized.
- If you have oily skin and pick something that feels too heavy → it can feel congesting or just unpleasant to use.
For what it’s worth, a heavier texture doesn’t automatically cause breakouts — what matters is your specific skin condition, the product’s overall formula, and how it actually feels when you use it. Even a product with great ingredients will end up sitting untouched if you don’t like how it feels on your skin. How a product feels isn’t just a matter of preference — it’s a matter of whether you’ll actually keep using it.
7. Will I actually use this consistently?
The last question, and maybe the most important one. Even the best product is useless if you don’t use it.
A product you’ll reach for every day without a second thought beats an expensive, complicated multi-step product you’ll eventually abandon. The way I put it: “A product that’s theoretically better but that you’ll stop using is far less useful than one you’ll actually stick with.” Skincare results come from consistency, in the end.
8. I check the back of the label before the front
“10% niacinamide,” “glass skin,” “barrier repair,” “pore-tightening,” “clinically proven” — it’s completely natural for front-label claims like these to catch your eye first when you’re shopping. But I always check the ingredient list and directions on the back before I trust the marketing on the front.
The front label shows what the brand wants to highlight. The ingredient list and usage directions tell you much more about how the product was actually formulated and how it’s meant to be used. For claims like “clinically proven,” I’d also look for information about the study behind the claim rather than taking the wording at face value. Specifically, I look at:
- What the key ingredient actually is
- Whether it overlaps with actives I’m already using
- Whether it contains fragrance or anything I personally react to
- The recommended frequency of use
- Whether adding it to my current routine would push irritation too far
In the end, I’m not looking for the “strongest” product — I’m looking for the one that fits my routine best.
A “Good Product” Isn’t Always the Right Product for You
Working as an esthetician has taught me one thing clearly: “a good product” and “a good product for me” can be two completely different things. A product can have excellent ingredients and great reviews and still be too irritating for your skin. Meanwhile, a product without flashy, trending ingredients can be the better choice if it feels comfortable on your skin and you’ll actually keep using it.
So when I’m evaluating a product, I ask myself “Does my skin need this right now?” before I ask “Is this a good product?”
Price works the same way. Being expensive doesn’t mean it’ll suit your skin better, and being cheap doesn’t automatically mean it’s lacking. What I actually look at isn’t the price tag itself — it’s whether the function is clear, whether the ingredients and texture suit my skin, and whether I can realistically keep using it.
Read reviews from people with skin similar to yours
Reviews are worth checking, but I never go by star rating alone. “Hydrating” from someone with dry skin and “hydrating” from someone with oily skin can mean completely different things. So when I read reviews, I also check the reviewer’s skin type, how long they used it, and what else they were using alongside it. A review from someone with skin similar to yours is far more useful.
The 8-Point Checklist Before You Buy (Save This)
Before you add a new product to your cart, just ask yourself these 8 questions.
- ☐ What problem am I actually trying to solve right now?
- ☐ What’s this product’s key ingredient?
- ☐ Am I already using something similar?
- ☐ Could this irritate my skin?
- ☐ Does it actually fit my current routine?
- ☐ Am I just trusting a number or a marketing claim at face value?
- ☐ Does the texture suit my skin?
- ☐ Can I realistically use this consistently?
+ Reviews and brand reputation are worth considering too, but the final call should come from how your own skin responds.
The Order I Actually Follow When Choosing a Product
This is the actual sequence I follow when choosing a product:
- Identify the problem I want to solve
- Check my current routine
- Check the key ingredient
- Look at the ingredient list and texture
- Check the irritation risk
- Think about whether I can use it consistently
- Only then compare price and brand
The key point is the last step — price and brand come last. No matter how cheap or well-known a product is, if it doesn’t make sense for your skin and routine, you probably won’t end up using it anyway.
Final Thoughts
