Glycolic acid is a type of alpha-hydroxy acid (AHA) that is commonly used in skincare products to reduce the appearance of wrinkles and acne. However, not all glycolic acid products are created equal. In this blog post, we will explore the scientific difference between neutralized and non-neutralized glycolic acid and why non-neutralized glycolic acid is more effective for reducing wrinkles and acne.
First, it's important to understand the difference between neutralized and non-neutralized glycolic acid. Neutralized glycolic acid has had a neutralizing agent added to it, typically sodium hydroxide, which raises the pH level of the glycolic acid. Non-neutralized glycolic acid, on the other hand, has not had a neutralizing agent added and therefore has a lower pH level such as the Facial Enhancement Cream by Dermatologist's Choice.
Clinical studies have shown that non-neutralized glycolic acid is more effective than neutralized glycolic acid when it comes to reducing wrinkles and acne. One study published in the Journal of the American Academy of Dermatology found that a non-neutralized glycolic acid peel was more effective in improving the appearance of fine lines and wrinkles than a neutralized glycolic acid peel.
Another study published in the Journal of Cosmetic Dermatology found that a non-neutralized glycolic acid peel was more effective in improving the appearance of acne than a neutralized glycolic acid peel. The study also found that non-neutralized glycolic acid was more effective in reducing the number of acne lesions and improving the overall appearance of the skin.
The reason for this difference in efficacy is that non-neutralized glycolic acid has a lower pH level, which allows it to penetrate the skin more effectively. Neutralized glycolic acid has a higher pH level, which can cause the acid to be less effective in penetrating the skin and reducing wrinkles and acne.
In conclusion, clinical studies have shown that non-neutralized glycolic acid is more effective than neutralized glycolic acid when it comes to reducing wrinkles and acne. If you're looking for a skincare product that contains glycolic acid, be sure to look for one that is non-neutralized to ensure that you're getting the most effective treatment possible.
To start incorporating a non-neutralized glycolic into your skincare routine, Dr. B. recommends starting with the Facial Enhancement Cream by Dermatologist's Choice Skincare.
