What role do vitamin C and hyaluronic acid play in anti-ageing cosmetics?

Vitamin C and hyaluronic acid are two key ingredients in anti-ageing cosmetics, each playing a specific role in improving skin health and combating the signs of ageing. Here is an overview of their functions:

Vitamin C:

  1. Antioxidant effect: Vitamin C is a powerful antioxidant that can protect the skin from the damaging effects of free radicals. Free radicals can cause cell damage, which can lead to premature skin ageing.
  2. Collagen production: Vitamin C plays an important role in the synthesis of collagen, a protein responsible for the elasticity and firmness of the skin. As we age, natural collagen production decreases and vitamin C can help to support this process.
  3. Skin whitening: Vitamin C can help reduce pigmentation spots and uneven skin tone by regulating the production of melanin and improving the appearance of hyperpigmentation.
  4. Reduction of fine lines and wrinkles: By promoting collagen production and protecting against oxidative stress, vitamin C can help reduce the appearance of fine lines and wrinkles.

Hyaluronic acid:

  1. Moisture binding: Hyaluronic acid is a natural substance that can bind moisture very effectively. It can increase the skin's ability to bind water and make it appear plumper and more hydrated.
  2. Filling effect: As hyaluronic acid is able to bind water, it can temporarily reduce the appearance of fine lines and wrinkles by slightly plumping up the tissue under the skin.
  3. Support of the skin barrier: Hyaluronic acid can help to strengthen the skin barrier, which in turn can protect the skin from environmental stresses.
  4. Smooth texture: Products with hyaluronic acid can improve the feel of the skin and make it softer and smoother.

Combinations of vitamin C and hyaluronic acid are often used in anti-ageing products to achieve synergistic benefits. While vitamin C promotes collagen production and protection against free radicals, hyaluronic acid helps to moisturize the skin and give it a smoother appearance. However, it is important to note that the effectiveness of products depends heavily on the concentration and quality of these ingredients. When choosing anti-ageing products, it is advisable to look for high-quality formulations and, if necessary, speak to a dermatologist to find the best products for your skin needs.
