Retinal Vitamin A (Vitamin A) (also known as Retinaldehyde) is vitamin A. The most effective that the FDA allows use in cosmetics. Since it can be converted to Retionic Acid within 1 natural process by the skin (it can convert faster than Retinol, it is more efficient than Retinol).

Vitamin A is currently the only cosmetic ingredient clinically recognized as effective for anti-aging and can reduce skin wrinkles.

Retinal when applied to the skin. Will be converted to Retionic Acid, a vitamin A in the form that the skin is ready to use

Products using Retinal must be packaged in a protective packaging that protects the formula from light, as the retinal deteriorates when exposed to light.

Suggested use ProtecTM OX And ProtecTM UV and ProtecTM SQ Or Bakuchiol * In the formula to help protect Vitamin A from quality deterioration (Click on ProtecTM SQ To examine the research results on the stability of Vitamin A group)

* From the research results " Bakuchiol to Stabilize Retinol and Polyunsaturated Lipids ”by Boxin Ou, PhD, International Chemistry Testing, Milford, MA USA. Bakuchiol At the rate of 2% of the Retinal in the formula

Formulas using Retinal should be oil-in-water only to avoid exposure to retinal air.

In the mixing process Please avoid the heat in the production. If heat is required in the formulation for the mixing process, please add Retinal at the last step. Blend to melt into the recipe. Without exposure to heat

The company sells 4 types of Vitamin A:

1. Retinyl palmitate / Retinol palmitate (liquid) Easy to use, inexpensive, but limited in performance.

3. Retinaldehyde (powder) Difficult to use, high price, high efficiency.

4. ActiveRelease Retinal (powder) Easy to use, moderate price, high efficiency.

The results of the experiment on the skin using Retinaldehyde 0.5% for 1 month on the arm surface (forearm).

Figure a shows the layers of keratin in the skin where v is vehicle and r is retinaldehyde 0.5% 1 month. The thickening of keratin levels was found.

Picture b Represents the class of transglutaminase in the skin where v is vehicle and r is retinaldehyde 0.5% 1 month. transglutaminase   Clearly thickened

Picture c Represents layers of involucrin in the skin where v is vehicle and r is retinaldehyde 0.5% 1 month. involucrin   Clearly thickened

Picture d Indicates the filaggrin layer in the skin where v is vehicle and r is retinaldehyde 0.5% 1 month. The level of filaggrin was clearly thicker.

Usage: For anti-wrinkle products in the form of a serum, lotion or cream.

Mixing method: Mix in the oil. Avoid using heat The formula should have a pH in the range of 3.5-6.5, the formula should have ActiveProtecTM OX 1% Always, Should use Vitamin B3 In conjunction with the research found that the use of Vitamin B3 Together with Retinal, the skin is more resistant to retinal irritants, making the retinal more active.

Rate of use: 0.01-0.1% (recommended 0.05%, warning: use of more than 0.1% causes skin irritation. Dangerous)

Product characteristics: Dark red-brown flake powder (Brown-Red Crystal) deteriorates quickly when exposed to UV light. ActiveRelease RetinalTM Instead, which is able to tolerate UV light better

Solubility: Can dissolve in oil

Storage: If you want to keep long-term Keep it frozen or keep in the refrigerator. (If able to freeze Please freeze) Do not expose to light, heat, seal the lid tightly, avoid exposure to air.
