Formulation Review for Dry Skin with Wrinkles and Dark Spots
Based on your skin type (dry with wrinkles and dark spots from acne) and the ingredients you've selected, here is a review of your proposed formulation:
1. Ingredient Compatibility
The ingredients you have chosen are generally compatible with each other. The pH requirements for the active ingredients like Vitamin C Ethyl Ether and Acetyl Hexapeptide-8 are within a range that can be managed in a single formulation. The Light Cream Maker is a cold-process emulsifier suitable for this type of formula, and the preservatives and chelating agent (Disodium EDTA) are compatible with the other components.
2. Ingredient Adjustments
Your selection of ingredients targets your stated concerns of dryness, wrinkles, and dark spots. The percentages for most ingredients are within the recommended usage rates and are appropriate for addressing these issues.
- Matrixyl 3000: The product description recommends a usage rate of 3-5%, with 3% being the recommended concentration. While 5% is within the acceptable range, reducing it to 3% is in line with the general recommendation and may still provide significant anti-aging benefits when combined with Acetyl Hexapeptide-8.
Consider adjusting the formula slightly as follows:
- Hyaluronic Acid Elastomer: 5%
- Acetyl Hexapeptide-8: 5%
- Matrixyl 3000: 3%
- Vitamin C Ethyl Ether: 3%
- Tris Biphenyl Triazine (nano): 10%
- Mild Preserved Eco: 1%
- Light Cream Maker: 1.5%
- Panthenol: 1%
- Disodium EDTA: 0.2%
- Purified Water: 70.3% (Adjusted to reach 100% total)
This adjustment maintains high levels of key actives while aligning Matrixyl 3000 with its recommended concentration.
3. Mixing Procedure
Here is a recommended mixing procedure for your formulation:
- In a clean container, combine the Purified Water and Disodium EDTA. Stir until the Disodium EDTA is completely dissolved.
- Add the water-soluble ingredients: Hyaluronic Acid Elastomer, Panthenol, and Vitamin C Ethyl Ether to the water mixture. Stir gently until they are fully dissolved or dispersed.
- Add the Light Cream Maker to the water mixture. Stir or blend gently (avoid high speed) until the mixture thickens and a cream texture is formed.
- Once the cream base has formed and cooled to below 40°C, add the heat-sensitive and final-stage ingredients: Acetyl Hexapeptide-8, Matrixyl 3000, Tris Biphenyl Triazine (nano), and Mild Preserved Eco.
- Stir gently until all ingredients are uniformly incorporated into the cream. Avoid over-mixing.
This procedure ensures that ingredients are added at the appropriate stages for optimal stability and texture.
