How are $50 and $500 skincare different?
What’s the difference between $50 drugstore and $500 premium products?
i.e. - am I paying for better stuff or am I crowdfunding [insert celebrity brand ambassador]’s new Birkin?
Well, it depends. On top of paying for billboards and high-profile endorsements, luxury brands also invest in developing novel products, defending their innovations, and sourcing better raw materials.
Soo I’ll just ChatGPT ingredient comparisons?
Well, it depends. Even identical ingredient lists can diverge in practice. Look in your fridge, both butter and yogurt are “100% milk extracts”. But depending on the processing steps they’ve gone through, the outcome product, contained nutrients, and benefits on our bodies are drastically different.
Wait, don’t go! Since it’s so case-dependent, let’s go over the top ingredients for the 4 most common skin concerns: moisturizing, brightening, anti-aging, and acne.
Moisturized, Hydrated, Glassy Skin
Let’s take a look at hyaluronic acid, a “water-magnet” ingredient that holds onto water molecules. More money might be needed to buy a deeper penetration, a purer concentration, or more active ingredients for better moisturization.
Hyaluronic acid at a lower molecular weight can penetrate deeper into the skin because of its smaller molecular size. High molecular weight, on the other hand, simply sits on the skin’s surface to give an immediate plumping effect. We can’t tell this just from the ingredients list, because both show up as just hyaluronic acid. (Kudos to The Ordinary for reporting their HA molecular weight)
Depending on how it’s sourced, hyaluronic acid might contain impurities, lowering the amount of HA per drop. You may also be paying for formulation synergy if other supporting ingredients are added in to improve the skin’s moisture retention. Some might be patented and trademarked, driving up costs.
Brightening Skin against Dullness, Dark Spots, Hyperpigmentation
Vitamin C (L-Ascorbic Acid) blocks excess melanin production to even out the skin tone, while also acting as an antioxidant to prevent inflammation from pollution. With this one, you might be paying for a better formulation, a stabler product, or a more potent form.
On its own, Vitamin C must be at 99% to penetrate the skin. To prevent pure Vitamin C from oxidizing and losing effectiveness (e.g. when it turns brown), products need to be at an acidic pH, have air-tight and dark-colored packaging, or include stabilizing ingredients like vitamin E or ferulic acid to extend its shelf life.
Some brands use more stable forms of Vitamin C derivatives (like SAP, MAP, THD), which might sacrifice potency and work at different concentration ranges. Which can be a good thing for sensitive skin.
Plump Skin with Collagen-rich Skin: Soft, Smooth, & Firm
Retinoids are the gold standard for anti-aging and for reducing fine lines and wrinkles, encouraging skin cells to renew themselves and produce more collagen to improve texture.
Fun fact: retinol was patented in 1989, only entering the public domain in 2009. In the 2010s, improvements made it less irritating, no longer the skin-stripping compound that flaked and irritated skin. (Ah, the wonders of modern medicine!)
With so many available derivatives and newer forms of retinoids balancing efficacy with gentleness, you’ll see where the money went: the type of active ingredient (some with a trailing ™), its packaging (opaque, air-tight pump; absolutely no droppers or open jars!), its concentration, and complementary ingredients like niacinamide or ceramides to buffer irritation.
For potent active ingredients like retinoids, it’s best to patch test first. Everyone’s skin is different, and even a well-researched chemical can cause irritation for some.
Get Rid of Acne for Clear Skin
Salicylic acid is a beta-hydroxy acid (BHA) that penetrates pores to dissolve oil and loosen the bonds between skin cells. This clearing of oil and dead cell buildup will unclog the pores, and prevent acne.
Expensive acne products might have a fine-tuned concentration and pH for better skin penetration. They may also include soothing ingredients like green tea extract or allantoin to counteract salicylic acid’s drying effects as it strips oil from pores.
What about other products?
Now we know the 4 key takeaways when comparing skincare:
Same Ingredients ≠ Same Product
I once sat on the floor of Shoppers for 20 minutes, word-for-word comparing the ingredients of “Hair Recipe” shampoo’s North American line with its Japanese version. Now I know it was a wasted effort, because the ingredients list won’t tell us the concentration, molecular weight, pH, or how it was processed, but all of which can lead to very different results.
Concentration and Form Matters
Being made from the exact same atoms, the chemical thalidomide came in 2 shapes – one was used for reducing morning sickness, the other caused birth defects. While skincare won’t have such severe effects, for potent active ingredients, a 0.5% change might make all the difference.
Ingredients for 1+1 > 2
Aside from adding multiple active ingredients for the same skincare goal, some formulations layer ingredients to buffer the irritation of the key ingredient. People have found that other than add-in buffering agents, you can also buffer side effects by applying these products differently: mixing them with moisturizers or layering them over a thicker, rich base.
Packaging
Choose opaque, airless pumps over open jars or droppers for ingredients that degrade in light or air. Think of how fast an apple browns. Today’s skincare is made to be more stable, slowing this degradation down but it can still happen over time due to inappropriate packaging.
Reputable Information Sources
10 years ago, there was no lip tint. Now, even a $15 lip tint can stain the lips and leave a glossy top layer. I don’t know how it’s done, but I’m pretty confident that science will keep bringing us more new and amazing products.
In the meantime, if you want to validate claims or understand mechanisms behind a specific issue, I recommend trustworthy sources like:
Dermatology associations for unbiased advice on active ingredients: American Academy of Dermatology on Anti-aging and Acne
Peer-reviewed journals for clinical evidence: open access Journal of Cosmetic Dermatology and Clinical, Cosmetic and Investigational Dermatology
