Ingredient Safety Validation gives consumers a repeatable method to vet skincare without a lab. Because marketing, packaging, and price reveal nothing about safety, the method starts with reading the actual ingredient list. Third-party databases like EWG and SkinSafe let you input a product or ingredient and get a risk rating, flagging potential cancer risks and hormone disruptors. Crucially, it is not just which ingredients are present but at what concentration, which is why third-party validation that accounts for concentration matters. Red flags to avoid include fragrance, petroleum-derived ingredients, and PEGs, along with misleading 'natural' claims. Harm from toxic products often only appears with long-term use.
Origin
Before founding OneSkin, Carolina was lost following online recommendations; her lab could test products on real skin, so she distilled that rigor into consumer-accessible steps using ingredient databases.
Core principles
- 01Marketing, packaging, and price tell you nothing about a product's safety.
- 02The ingredient list, not the branding, is where the truth lives.
- 03Concentration matters as much as which ingredients are present.
- 04Third-party databases can flag cancer and hormone-disruption risks.
How to run it
- 1
Ignore the marketing
Disregard packaging, price, and branding as signals of safety; expensive, well-marketed products are often full of harmful ingredients.
Watch out Toxicity may not show immediately; harm often appears only with long-term use.
- 2
Read the ingredient list
Examine the full ingredient list and run it through a third-party database like EWG or SkinSafe to get a risk rating.
Pro tip Green usually means safe, red means potential risk on EWG.

Check concentration and red flags
Assess concentrations, not just presence, and avoid fragrance, petroleum-derived ingredients, and PEGs.
Pro tip Be careful with 'natural' labels, which can be misleading.
In the wild
Carolina described applying products to lab-grown human skin to evaluate safety directly.
→ Clean products leave the skin fine or better, while toxic ones cause the skin to degenerate, mirroring the long-term rashes and irritation consumers eventually see.
Host Hala shared that she never puts fragrance on her face despite expensive fragranced products having great packaging and marketing.
→ Avoiding fragrance is presented as one of the best things you can do for anti-aging.
Common mistakes
Trusting price and packaging
Assuming an expensive, well-marketed product is safe leads people to apply fragrance-laden, toxic formulas.
Ignoring concentration
Checking only which ingredients are listed misses that the concentration is what determines actual risk.
Is it for you?
Best for
Consumers who want a repeatable way to vet skincare safety without a lab of their own.
Not ideal for
People who trust brand claims at face value and won't check ingredient lists.
From the transcript
“My recommendation is always to look the ingredient list.”
“It's not like which ingredients are there but at what concentration and that matters a lot.”
