Large molecule malic and mandelic acids: better sensitive skin chemical exfoliators

In the dynamic world of skincare, where innovation and science continually converge, alpha hydroxy acids (AHAs) have evolved into a more refined selection of options that can be tailored to support even the most sensitive skins.

When AHAs first came on the scene many years ago, glycolic acid was all the rage, and for good reason as it is a powerful skin refiner. But not everyone could use glycolic due to its intensity.

Today we have larger molecule alpha hydroxy acids to help us out. 

Sensitive skin individuals often prefer larger molecule AHAs in skincare because they tend to be gentler and less irritating compared to smaller AHAs. Larger AHAs, such as lactic acid and gluconic acid, have molecules that penetrate the skin more slowly and evenly. This slower penetration reduces the likelihood of irritation, making them better tolerated by sensitive skin types.

Furthermore, larger AHAs have hydrating properties and can help improve the skin's moisture barrier function. They exfoliate the skin's surface while also attracting moisture, leading to smoother, softer, and more hydrated skin without causing excessive dryness or irritation. Overall, larger molecule AHAs provide effective exfoliation and skin renewal benefits without exacerbating sensitivity, making them a preferred choice for those with sensitive skin.

Malic Acid: The Gentle Exfoliator Derived from apples, malic acid is a natural alpha-hydroxy acid known for its mild exfoliating abilities. Ideal for sensitive skin, it unclogs pores, promotes hydration, and acts as an antioxidant, protecting against environmental damage.

This AHA also plays a crucial role in enhancing hydration. By improving the skin's moisture retention, malic acid helps create a more supple and plump appearance. Additionally, its antioxidant properties aid in combating free radicals, protecting the skin from environmental damage and oxidation.

Mandelic Acid: Versatile and Gentle From bitter almonds, mandelic acid's larger molecular structure makes it gentle on the skin. Its versatility shines in addressing acne, fine lines, and uneven skin tone.

Moreover, mandelic acid is renowned for its antibacterial properties, making it an excellent choice for individuals struggling with acne-prone skin. By reducing inflammation and preventing bacterial growth, it aids in managing breakouts without causing excessive dryness or irritation.
