Formulation Advice

Regarding your cosmetic formulations, here is some advice based on your questions and the previous staff response:

Rose Hip Oil Usage

For all three formulations, Rose Hip Oil is a natural oil that can be used in varying amounts depending on your skin's needs. As the staff mentioned, you can start by adding Rose Hip Oil at a concentration of 5-10% in each formula. Since it is an oil, it should be incorporated into the oil phase of your emulsion.

Formula 1: Whitening and Anti-Wrinkle

Your formula includes:

• Apple Stem Cell Extract 5 %
• Stabilized Vitamin C 20%
• Green Tea Extract 5 %
• Phenoxyethanol 1%
• Light Cream Maker 10%
• Disodium EDTA 0.2%
• Rose Hip Oil (add 5-10%)
• Water

This looks like a good base for a whitening and anti-wrinkle cream. Ensure the pH is suitable for the Stabilized Vitamin C you are using.

Formula 2: Soft and Smooth Skin with Whitening

Your formula includes:

• Royal Jelly Fresh 10%
• Alpha Arbutin 2 %
• Pure Aloe Vera Gel 30%
• Phenoxyethanol 1%
• Light Cream Maker 1.5%
• Disodium EDTA 0.2%
• Rose Hip Oil (add 5-10%)
• Water

The staff recommended adding Vitamin B3 (5%) and GlucoBright (3-4%) to this formula. These ingredients work well with Alpha Arbutin for enhanced whitening and skin texture improvement. Note that if using Royal Jelly Extract powder, the recommended usage rate is typically lower than 10%.

Formula 3: Anti-Wrinkle Eye Area

Your formula includes:

• Argireline 10%
• Matrixyl 3000 5%
• REGU-AGE 5%
• Phenoxyethanol 0.5%
• Light Cream Maker 1.5%
• Disodium EDTA 0.2%
• Rose Hip Oil (add 5-10%)
• Water

To make the texture thicker, as the staff suggested, you can increase the concentration of Light Cream Maker. You can try increasing it to 2-3% to achieve a thicker consistency for your eye cream. Ensure the pH is within the recommended range for the active ingredients like Argireline and Matrixyl 3000.

Remember to adjust the water percentage in each formula to make the total 100% after adding Rose Hip Oil and any other suggested ingredients.
