When shopping for skincare, cosmetics, or personal care products, you've likely come across the term "dermatologically tested" on labels and advertisements. It sounds reassuring, but what does it actually mean? Is it a guarantee of safety and effectiveness, or just a marketing buzzword?
In this blog post, we’ll break down the meaning of dermatologically tested, how it differs from other clinical claims, and what consumers should look for when choosing skin-friendly products.
What Does "Dermatologically Tested" Mean?
"Dermatologically tested" indicates that a product has undergone testing under the supervision of a dermatologist—a medical expert specializing in skin health. This test is typically conducted to assess the product’s potential to cause skin irritation or allergic reactions.
However, there are no standardized regulations that define exactly how these tests should be conducted. The claim simply means that a product has been tested, but it does not guarantee that it is completely safe for all skin types.
How Are Dermatological Tests Conducted?
The testing process for dermatologically tested products varies, but here are the most common methods used:
1. Patch Testing (Skin Compatibility Test)
Patch testing one of the most common ways to evaluate a product’s potential to cause irritation or allergies. A small amount of the product is applied to a patch, which is then placed on a participant’s skin (usually on the back or forearm) for 24 to 48 hours. The dermatologist then assesses the skin’s reaction.
2. In-Use Testing
Participants use the product as intended (e.g., applying a moisturizer daily) over a period of time, while dermatologists monitor for any adverse reactions such as redness, itching, or breakouts.
3. Hypoallergenic Testing
For products claiming to be hypoallergenic, additional testing is done to ensure they have a low risk of causing allergic reactions. This often involves a larger group of participants with sensitive skin.
4. Non-Comedogenic Testing
If a product claims to be non-comedogenic (meaning it won’t clog pores), it may undergo specific dermatological tests to see if it causes acne or breakouts.
Does "Dermatologically Tested" Mean the Product Is Safe for Everyone?
Not necessarily. Since there is no universal standard for dermatological testing, the claim does not guarantee:
That the product is 100% safe for all skin types
That it is free from allergens or irritants
That it has undergone extensive clinical trials
It simply means the product has been tested under dermatological supervision, but the results of those tests can vary widely.
What to Look for Beyond "Dermatologically Tested"
To make a truly informed decision, here are a few extra things to check:
Clinical Study Details
Some brands provide specific details on how their dermatological testing was conducted. Look for phrases like:
“Clinically tested on X number of participants”
“Dermatologically tested on sensitive skin”
“Independent third-party clinical study”
Ingredient List
If you have sensitive skin, scan the ingredient list for known irritants such as fragrances, sulfates, parabens, and alcohol.
Certifications & Seals
Look for products certified by independent organizations such as:
The National Eczema Association (for sensitive skin)
Allergy UK (for allergy-friendly claims)
Non-Comedogenic or Hypoallergenic Certifications
Consumer Reviews & Dermatologist Recommendations
Check real user reviews and seek dermatologist-approved recommendations, especially if you have specific skin concerns like acne, rosacea, or eczema.
Is "Dermatologically Tested" Enough?
The "dermatologically tested" label can be a good indicator that a product has undergone some level of skin testing, but it doesn’t always mean it is safe for everyone. Since there are no strict regulations governing this claim, it’s always wise to dig deeper into the type of testing conducted, ingredient list, and third-party certifications before making a purchase.
When in doubt, consult a dermatologist to determine the best products for your skin type.
