Vitamin A in cosmetics

Introduction to Cosmetic Use

Vitamin A is one of the most well-researched and effective anti-aging ingredients in the cosmetics industry. Its various forms (retinoids) offer a wide range of skin-renewing properties in all layers of the skin.

Forms of Vitamin A in Cosmetic Products

Retinoids - Derivatives of Vitamin A

Compounds derived from Vitamin A that work in the skin with varying potency:

Retinol (Vitamin A)

The most common cosmetic form:

  • Alcohol form of Vitamin A
  • Converts to retinoic acids in the skin
  • Binds to nuclear receptors (RAR, RXR)
  • Initiates regulation processes of over 500 genes

Other Retinoids

Retinoic Acid:

  • Most active form
  • For medical use only
  • Most irritating, but most effective

Retinyl Esters:

  • Milder option
  • Slower conversion to active form
  • Suitable for sensitive skin

Encapsulated Retinol Formulations

Advanced formulations used in DELTA products:

  • Time Controlled Diffusion Retinol: Time-controlled release over 8 hours

  • Encapsulated microspheres: Even release into the skin

Bio-retinoids - Vitamin A-like Effects

Bakuchiol:

  • Plant-based alternative with retinoid-mimicking properties

  • Does not cause typical retinoid side effects
