What a Skincare Educator Knows That You Don’t
Ella Cressman has spent her career inside the skincare industry — as a licensed esthetician, certified international skincare educator, and formulation consultant. She’s seen the inside of manufacturing facilities, reviewed ingredient supplier documentation, and watched brands make marketing claims that bear little relationship to the science.
In this two-part conversation with Nour Abochama on Nourify & Beautify, Ella pulls back the curtain on practices that the industry would prefer consumers didn’t know about.
“The skincare industry is largely self-regulated,” Ella explains. “Brands can make claims that sound scientific without any scientific backing. They can use ingredients at concentrations too low to be effective and still feature them prominently on the packaging. And they can use the word ‘natural’ to mean almost anything.”
The Marketing Claims Problem
The most pervasive issue in the skincare industry isn’t dangerous ingredients — it’s misleading marketing. Ella identifies several categories of claims that consumers should approach with skepticism:
“Clinically Proven” Claims
This phrase sounds rigorous but can mean almost anything. A brand can conduct a small, non-peer-reviewed consumer perception study — asking 20 people whether they think their skin looks better after using a product — and call the results “clinically proven.”
Legitimate clinical evidence involves:
- Randomized controlled trials
- Adequate sample sizes (typically 50+ participants)
- Objective measurements (not just self-reported perception)
- Peer review and publication
- Studies conducted on the specific product formulation, not just individual ingredients
”Dermatologist Tested” vs. “Dermatologist Recommended”
“Dermatologist tested” means a dermatologist evaluated the product — it says nothing about whether they found it safe or effective. “Dermatologist recommended” means a dermatologist recommends it — but brands often pay for these endorsements.
Neither claim tells you whether the product has been tested in a rigorous clinical trial.
Ingredient Concentration Games
Brands are required to list ingredients in descending order of concentration. This creates an opportunity for what Ella calls “fairy dusting” — including a trendy ingredient at a concentration too low to be effective, but high enough to feature it prominently in marketing.
“You’ll see a product marketed as a ‘vitamin C serum’ where vitamin C is listed 15th on the ingredient list,” Ella explains. “At that concentration, it’s not doing anything meaningful for your skin.”
Effective vitamin C concentrations in clinical research are typically 10-20%. If vitamin C appears near the bottom of an ingredient list, the concentration is likely well below 1%.
The “Natural” and “Clean” Labeling Problem
These terms have no legal definition in the United States. Any brand can use them on any product.
“Natural” doesn’t mean:
- Free from synthetic ingredients
- Free from preservatives
- Safer than conventional products
- Better for your skin
Some of the most potent skin irritants are natural (poison ivy, for example). Some of the safest, most effective skincare ingredients are synthetic.
“Clean beauty” is similarly undefined. Different brands and retailers use different criteria for what qualifies as “clean.” EWG’s “clean” standard differs from Sephora’s “clean” standard, which differs from Credo Beauty’s standard.
This doesn’t mean “natural” and “clean” products are bad — many are excellent. It means these labels alone tell you nothing about safety or efficacy.
Ingredients to Actually Pay Attention To
Rather than avoiding entire categories of ingredients, Ella recommends focusing on specific ingredients with documented safety concerns:
Fragrance / Parfum
The word “fragrance” on an ingredient list can legally represent a blend of hundreds of undisclosed chemicals. Many fragrance ingredients are known sensitizers and allergens. For sensitive skin, fragrance-free products are generally safer.
Certain Preservatives
Parabens have been controversial, though the scientific consensus is that they’re safe at concentrations used in cosmetics. More concerning are formaldehyde-releasing preservatives (DMDM hydantoin, imidazolidinyl urea, diazolidinyl urea) which can cause contact dermatitis in sensitive individuals.
Certain Sunscreen Ingredients
Oxybenzone and octinoxate have raised concerns about hormone disruption, though the evidence in humans at typical exposure levels is not conclusive. Mineral sunscreens (zinc oxide, titanium dioxide) are generally considered safer alternatives.
Retinoids During Pregnancy
Vitamin A derivatives (retinol, retinyl palmitate, tretinoin) should be avoided during pregnancy due to potential teratogenic effects.
How to Build a Skincare Routine That Actually Works
Ella’s framework for building an effective, safe skincare routine:
1. Start with the basics. A good cleanser, moisturizer, and SPF will do more for your skin than any trendy serum. Master these before adding complexity.
2. Introduce one new product at a time. This allows you to identify which product causes a reaction if you experience one.
3. Give products time to work. Most active ingredients (retinoids, vitamin C, niacinamide) require 8-12 weeks of consistent use before you’ll see meaningful results. Don’t abandon a product after two weeks.
4. Match products to your skin type and concerns. A product that works beautifully for dry skin may cause breakouts on oily skin. Know your skin type.
5. Less is often more. A 10-step routine isn’t necessarily better than a 3-step routine. Layering too many actives can cause irritation and counteract each other’s benefits.
6. Patch test new products. Apply a small amount to your inner arm for 24-48 hours before using on your face.
Key Takeaways
- “Clinically proven” is a marketing term that can mean almost anything — look for peer-reviewed, published clinical trials
- “Natural” and “clean” have no legal definitions — these labels alone tell you nothing about safety
- Ingredient “fairy dusting” is common — trendy ingredients listed near the bottom of the list are likely present at ineffective concentrations
- Fragrance/parfum can hide hundreds of undisclosed chemicals — fragrance-free is safer for sensitive skin
- Build your routine on basics (cleanser, moisturizer, SPF) before adding actives
- Give products 8-12 weeks to show results before judging their effectiveness
