Vitamin A (Vitamin A) Retinal type (also known as Retinaldehyde) is vitamin A. The most effective that the FDA is allowed to be used in cosmetics.

Vitamin A (Vitamin A) Retinal type (also known as Retinaldehyde) is vitamin A. The most effective that the FDA is allowed to be used in cosmetics. Because it can be converted to Retionic Acid in one natural process by the skin (can be converted faster than Retinol, therefore more effective than Retinol).

At present, vitamin A is still the only cosmetic ingredient that is clinically recognized as effective in Anti-Aging and can reduce skin wrinkles.

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

Retinal-based products must be packaged in a package that protects the formulation from light, as Retinal deteriorates when exposed to light.

recommended use Protec™ OX and Protect™ UV and Protec™ SQ or Bakuchiol* in the formula to help protect Vitamin A from deterioration (click on Protec™ SQ To verify the research results on the stability of Vitamin A group)

*According to research results " Bakuchiol to Stabilize Retinol and Polyunsaturated Lipids" by Boxin Ou, PhD, International Chemistry Testing, Milford, MA USA, using Bakuchiol at 2% Retinal rate in formula

Retinal-based formulations should be in oil-in-water form only to avoid retinal exposure to air.

in the mixing process Please avoid heat in production. If the recipe requires heat in the mixing process, please add Retinal at the end. Blend to dissolve into the recipe. without being exposed to heat

The company sells 5 types of Vitamin A:

1. Retinyl palmitate / Retinol palmitate (liquid) Inexpensive but limited performance Because the conversion to Retionic Acid requires several steps. before the skin can absorb it

2. Retinyl Acetate (powder) Inexpensive but limited performance Because the conversion to Retionic Acid requires several steps. before the skin can absorb it.

3. Retinaldehyde (powder) High price, high efficiency, because the skin can be converted to Retinoic Acid in one step and can be used immediately.

4. ActiveRelease Retinal (powder) Easy to use, moderate price, highly effective because the skin can be converted into Retinoic Acid in one step and can be used immediately

5. Retinol (powder) Moderate price, moderate performance The skin can be transformed into Retinaldehyde (the type in 3,4) before changing to Retinoic Acid (combining 2 steps, therefore having lower efficiency Retinaldehyde which can be converted to Retinoic Acid in 1 step)

6. Perfect-A™ high price, high performance high stability And does not irritate the skin like vitamin A. Other forms are vitamin A. newly developed to solve the weaknesses of other forms of vitamin A, both in terms of absorption skin irritation and stability

7. Retinyl Retinoate high price, high performance high stability And does not irritate the skin like vitamin A. Other forms are vitamin A. newly developed to solve the weaknesses of other forms of vitamin A, both in terms of absorption skin irritation and stability

Experimental results on the skin using Retinaldehyde 0.5% for a period of 1 month on the forearm area.

Figure a shows the keratin layer in the skin, where v is the vehicle and r is retinaldehyde 0.5%. 1 month, the level of keratin is clearly thickened.

picture b represents the class of skin transglutaminase, where v is vehicle and r is retinaldehyde 0.5%. transglutaminase   Clearly thickened

picture c represents the layer of involucrin in the skin where v is vehicle and r is retinaldehyde 0.5%. involucrin   Clearly thickened

picture d represents a layer of filaggrin in the skin, where v is vehicle and r is retinaldehyde, 0.5%. 1 month, filaggrin levels are clearly thickened.

Use: For anti-wrinkle products in the form of serums, lotions or creams.

How to mix: Mix in the oil Avoid using heat. Formulation should have pH in the range 3.5-6.5, Formulation should have ActiveProtec™ OX 1% Always, should use Vitamin B3 together, because research results showed that the use of Vitamin B3 Together with Retinal, the skin is more resistant to irritation from Retinal, making Retinal more effective.

Utilization rate: 0.01-0.1% (recommended 0.05%, warning: using more than 0.1% causes skin irritation. can be dangerous)

Product characteristics: Dark red-brown flakes (Brown-Red Crystal) deteriorate quickly when exposed to UV light. Recommended to use. ActiveRelease Retinal™ instead, which will be more resistant to UV light.

Solubility: can dissolve in oil

Storage: For long-term storage Freeze or store in the refrigerator. (If it can be frozen please freeze) Do not expose to light, heat, seal the lid tightly, avoid exposure to air.
