Esthetician's Guide to Hyaluronic Acid

This condition appears in the ASCP SkinPro app

What is Hyaluronic Acid?

A strong humectant fluid present in the dermis of the skin, the joints of the body, and the eyes. In the dermis, it is part of the extracellular matrix responsible for holding water in the reticular dermis and helping to provide cushion and support to the skin.

What Should I Know About Hyaluronic Acid?

  • In skin care products, it is a strong hydrator, helping to bind water to the skin surface; in dermatology and plastic surgery, it is used in injectable fillers for the face.
  • Helps reduce the signs of aging, poor surface texture, and elastosis.
  • Hyaluronic acid presence dwindles with age, attributable to both intrinsic aging and breakdown from enzymes in the skin triggered by reactive oxygen species (free radicals).
  • The hyaluronic acid molecule is too large to penetrate the skin; so while it is an exceptionally effective hydrating agent, it is too big to penetrate the skin topically, and its application does not replace hyaluronic acid missing from the dermis.
  • Often blended into products with other anti-aging ingredients such as peptides, collagen stimulants, and antioxidants.

Hyaluronic Acid Treatment Considerations

  • Use with dry and dehydrated skin.
  • Improves the appearance of surface texture, fine lines and wrinkles, and lack of firmness.
  • Helps retain moisture for longer periods of time.

Hyaluronic Acid Contraindications

  • Use intake forms to screen for potential allergies that may affect the individual client.
