Everything you need to know about azelaic acid
It's a mystery why there is so little focus on some ingredients in skincare when research has proven that they are worth the attention. Azelaic acid is such an ingredient. Studies have proven that azelaic acid can make a big difference when it comes to preventing and reducing breakouts. It helps to visibly fade red marks and discolourations after breakouts and helps to achieve a smoother, more even complexion. Azelaic acid is suitable for all skin types and can help to reduce skin sensitivity. In short, azelaic acid is an ingredient you should want to know more about!
What is azelaic acid?
Chemically, azelaic acid is a dicarboxylic acid. (Don't worry, this is a good kind of acid.)
Azelaic acid is obtained from grains such as barley, wheat and rye. When used in skincare products, it is typically lab-engineered for maximum stability and effectiveness.
What does azelaic acid do?
On the skin it has the same effect as a mild, leave-on exfoliant. It helps to unclog pores and refine the skin's surface. Azelaic acid is also a potent antioxidant and reduces the factors in the skin that cause sensitivity and bumps.
Most research has been carried out on products that are only available on prescription, with a concentration between 15% and 20%, but even in lower concentrations, azelaic acid can make a big difference.
The benefits of azelaic acid in skincare products
Products with a concentration of azelaic acid of 10% or less are not easy to find, because very few brands have discovered the great benefits of this ingredient. In addition, it's not the easiest ingredient to formulate. When a product with azelaic acid is not properly formulated, the texture can become grainy, which may cause skin problems.
If you are in doubt whether you need a cosmetic product with azelaic acid or a prescription product, know that products with 10% azelaic acid can make a big difference when it comes to visible improvements in skin structure and skin tone.
For some stubborn skin concerns, it is advisable to use a prescription product with a higher concentration of azelaic acid. You can consult a dermatologist or skin therapist to see which product is most suitable for you and how to include it in your skincare routine.
The science behind products with azelaic acid
Researchers have a theory about how azelaic acid works. It is suspected that azelaic acid interrupts the progression of emerging skin concerns in the upper layers. Without this inhibiting benefit, they can progress to skin concerns such as pigmentation spots, redness, scars, a dull complexion and increased sensitivity. Azelaic acid 'tells' the cells in the upper skin layers how to behave, which results in a smoother and visibly healthier skin, regardless of your age, skin type or skin concerns.
Continuous research on azelaic acid led to the development of our 10% Azelaic Acid Booster. The azelaic acid in this product tackles a wide range of skin concerns. It contains 0.5% salicylic acid that penetrates into the pores as well as a combination of plant extracts that soothe and brighten skin and skin restoring adenosine to reduce signs of ageing.
You can easily add the 10% Azelaic Acid Booster to your skincare routine. Apply it all over your face or just to the affected areas once or twice a day after cleansing, toning and exfoliating. You can apply it directly to the skin, but also mix it with your favourite serum or night cream. Always use a moisturiser with SPF 30 or higher during the day.
This treatment has the texture of a cream-gel. This makes it suitable for all skin types and can be used in combination with all our other products, including our AHA and BHA exfoliants. You may wonder how these products relate to each other...
How does azelaic acid relate to alpha-hydroxy acid (AHA) and beta-hydroxy acid (BHA)?
These three ingredients have similarities, but also a few interesting differences. Although azelaic acid, if properly formulated, has an exfoliating effect (just like AHAs and BHA, the pH value is important), it does not exfoliate in the same way and not as effectively as glycolic acid and lactic acid (AHAs) or salicylic acid (BHAs).
In contrast, azelaic acid has an added value to AHAs and BHA when it comes to improving uneven skin tone and other skin concerns.
There is no reason not to use an AHA or BHA exfoliant in addition to a product with azelaic acid. In fact, it can be the perfect combination for tackling different skin concerns, ranging from bumps to uneven skin tone and minimising the signs of ageing.
