Do you have a sensitive skin? Do you find it difficult to find products that don’t irritate your skin? If so, recently published study by Staci Brandt and Dr. Peter Lio may offer some hope.
As I mentioned in the previous post talking about the use of makeup on acne, the regulations concerning cosmetic and personal care products labeling is very lax. Terms like hypoallergenic and noncomedogenic are not regulated. Anyone can claim their products are hypoallergenic, and they can do that without testing the products. This puts people with sensitive skin at a difficult position, and often your only choice is to test different products to find some that work with your skin.
So I’m very happy to see testing done on these products. In this study the researchers tested 10 different Cetaphil products on over 2000 men and women.
The products were tested with what’s known as repeat insult patch test. In practice this means the products were applied on the skin for 24 to 48 hours, 3 times a week for 3 weeks. This procedure tested irritancy of the products. Once the irritancy tests were done, skin sensitization was tested 2 weeks later. In the sensitization test, the same products were again applied to the skin (after the 2 week washout period).
The results showed that none of the products caused skin irritation or sensitization, thus they were deemed as hypoallergenic. Many of these products contain some comedogenic ingredients, which further shows you shouldn’t pay too much attention comedogenicity of individual ingredients in finished products – as I talked in the makeup post.
Here are the products they tested:
- Daily Facial Moisturizer, SPF 15
- Daily Facial Moisturizer with sunscreen SPF 50
- Moisturizing Lotion
- Daily Facial Cleanser
- Moisturizing Cream for Dry, Sensitive Skin
- Daily Advance Lotion for Dry Sensitive Skin
- Dermacontrol Foam Wash
- Dermacontrol Moisturizer SPF 30
- Restoraderm Skin Restoring Body Wash
- Restoraderm Skin Restoring Moisturizer
You might want to consider those as an option if you are looking for something to use on sensitive skin.
I should say that one of the study authors, Stacy Brandt, works for Galderma, the company that makes Cetaphil products. I wouldn’t take this to mean that the study is invalid. The other author was an independent doctor, with no disclosed conflicts of interest, and it was published in a reputable journal. The study was also very large, the products were evaluated on over 2000 people. If the company was just looking for a study to prop up marketing material, they wouldn’t need it to be this big. So I’m inclined to take it seriously (that’s why I wrote about it).
