Azelaic acid is a dicarboxylic acid that naturally occurs in the skin. It works by inhibiting the growth of acne-causing bacteria and reducing the production of keratin, which can clog pores. Additionally, azelaic acid has been found to have anti-inflammatory properties, making it beneficial for individuals with rosacea.
Azelaic acid primarily works by normalizing the keratinization process, which prevents the formation of comedones (clogged pores). It also reduces the production of inflammatory mediators and inhibits the growth of Propionibacterium acnes, a bacterium associated with acne. Additionally, azelaic acid has been found to suppress the production of melanin, making it beneficial for individuals with hyperpigmentation concerns.
Retinol is a form of vitamin A that is widely used in skincare products. It is known for its ability to stimulate collagen production, increase cell turnover, and improve the appearance of fine lines and wrinkles. Retinol is available over the counter and is a milder alternative to prescription retinoids.
Retinol works by binding to specific receptors in the skin and activating them. This, in turn, stimulates the production of collagen and increases cell turnover, leading to a smoother and more youthful complexion. Retinol also helps to unclog pores, reduce the formation of acne lesions, and regulate sebum production.
Can You Use Azelaic Acid with Retinol?
Both azelaic acid and retinol are powerful ingredients with proven benefits for the skin, but can they be used together? To answer this question, it is crucial to understand the chemistry behind their interaction.
Chemistry Behind Azelaic Acid and Retinol
Azelaic acid is generally considered a stable ingredient and can be used in combination with other skincare ingredients without significant issues. On the other hand, retinol is more unstable and can be sensitive to changes in pH and certain ingredients. It is known to oxidize and degrade when exposed to light and air.
When azelaic acid and retinol are combined, there is a potential risk of inactivation or reduced efficacy of retinol due to the pH level and potential chelation (binding) between the two ingredients. Azelaic acid typically functions best at a slightly acidic pH (around pH 4-5), while retinol typically requires a more neutral to slightly alkaline environment for optimal effectiveness (around pH 5.5-7).
However, the specific formulation of the products containing azelaic acid and retinol can vary, and some manufacturers may have overcome these challenges by carefully formulating their products to ensure stability and efficacy.
Can You Use Them Together?
Yes, azelaic acid and retinol can be used together in a skincare routine. Both azelaic acid and retinol are effective topical treatments for various skin concerns, and they work in different ways.
