Formulating with Polyhydroxy Acids (PHAs)

Discover a cutting-edge skincare ingredient that’s causing quite a stir. Polyhydroxy acids (PHAs) are chemical exfoliants that are much more gentle than AHAs or BHAs, are very hydrating and are suitable for even sensitive skin.

If you are interested in the benefits of hydroxy acids but concerned about the sensitivity that AHAs and BHAs can cause then you may have just discovered your new favourite skincare ingredient!

The benefits of polyhydroxy acids (PHAs) include:

• Chemical exfoliator: reveals smoother, brighter skin and reduces congestion.
• Gentle, compared to AHAs/BHAs.
• Protects skin from some of the damaging effects of UV radiation and reduces the most common signs of photoaging.
• Helpful in maintaining collagen levels within the skin, as well as improving its elasticity and tone, and reducing the appearance of sallowness.

• Can help reduce the appearance of hyperpigmentation.
• Antioxidant.
• Hydrating and moisturizing.
• Enhances stratum corneum barrier function.
• Reduces transepidermal water loss (TEWL).
• Suitable for all skin types, including sensitive.

In this class, you will discover:

• The benefits of PHAs in detail, including references to scientific studies.
