What is Azelaic Acid and how can Azelaic Acid help your concerns?

Azelaic Acid is a new emerging solution, when in the past, no one really knew about it, but now everyone wants to try it out at least once. Azelaic acid helps improve skin texture and skin problems such as acne scars, hyperpigmentation and rosacea. It also helps to repair damaged tissue for a brighter, and more even skin tone. 

Azelaic acid is a skin-friendly dicarboxylic acid and can be derived from grains like barley, wheat, and rye. It has unique properties and is one of the more highly sought-after ingredients as it significantly improves the appearance of skin blemishes, helps fade post-acne marks and other discolorations, refines skin texture,  and even reduces skin sensitivity. 

HOW TO USE

1. After cleansing, prep the skin with the toner.
2. Dispense 1-2 drops on hands or directly on the face.
3. Spread evenly on the face and gently pat to aid absorption.
4. Can be used day and night. 
5. Use sparingly to give skin a thorough reset.
