Retinal (Retinaldehyde) Extract

Vitamin A (Vitamin A) in the form of Retinal (also known as Retinaldehyde) is a highly effective form of Vitamin A permitted by the Thai FDA for use in cosmetics. It can be converted into Retinoic Acid through a single natural conversion process in the skin (it is converted faster than Retinol, making it more effective than Retinol).

Currently, Vitamin A is the only cosmetic ingredient medically recognized for its Anti-Aging benefits and ability to reduce wrinkles. When Retinal is applied to the skin, it is converted into Retinoic Acid, a form of Vitamin A that is readily usable by the skin.

Products containing Retinal must be packaged in containers that protect the formulation from light, as Retinal can degrade when exposed to light. It is recommended to use Protec™ OX, Protec™ UV, and Protec™ SQ or Bakuchiol in the formulation to help protect Vitamin A from degradation (click on Protec™ SQ to view research results on the stability of Vitamin A ingredients).

According to the research “Bakuchiol to Stabilize Retinol and Polyunsaturated Lipids” by Boxin Ou, PhD, International Chemistry Testing, Milford, MA USA, Bakuchiol should be used at a rate of 2% of the Retinal in the formulation.

Formulations containing Retinal should be in oil-in-water form only to minimize Retinal's exposure to air. During the mixing process, please avoid heat during production. If heat is necessary during the mixing process, please add Retinal at the final stage and mix until fully incorporated into the formulation without exposing it to heat.
