Serum Formulation Feedback

Thank you for sharing your serum formulation designed to address skin issues from steroid use, including dryness, oiliness, and flaking on the chin. The ingredients you've selected are generally well-suited for supporting skin barrier repair and hydration, which are crucial for skin recovering from steroid use.

Your formula includes:

• Purified Water
• Ceramide Complex
• Vitamin B12
• Atopic-Telmesteine™
• 1,2 Hexanediol
• MOIST72™
• Satin Cream Maker™
• Cyclomethicone

Let's evaluate the feasibility and potential adjustments:

Formula Feasibility and Ingredients

Most of the ingredients you've chosen are appropriate for a soothing and hydrating serum aimed at repairing the skin barrier:

• Ceramide Complex: Ceramides are excellent for restoring the skin barrier, which is often compromised after steroid use. The type found in the search results (Ceracare™ Liposome-3) is specifically noted as suitable for skin affected by steroid use.
• Vitamin B12: Known for its anti-inflammatory and regenerative properties, it can help soothe irritated skin and support cell turnover.
• MOIST72™: This provides long-lasting hydration and is also recommended for use with Ceramide Complex for dry, peeling skin.
• 1,2 Hexanediol: Acts as a humectant, solvent, and preservative booster, which is beneficial for the formula's hydration and stability.
• Satin Cream Maker™: This is a suitable emulsifier for creating a serum/light cream texture, capable of handling the small amount of silicone.
• Cyclomethicone: Provides a smooth, non-greasy feel and helps with spreadability.

Potential Adjustments and Considerations

1. Ceramide Complex Concentration: The specific Ceramide Complex found (Ceracare™ Liposome-3) has a recommended usage rate of 0.1-3%, with 1% being typical. Your proposed 5% is higher than this recommendation. While it might not cause issues, using 1-3% could be sufficient and more cost-effective. It's worth confirming the recommended usage rate for the specific Ceramide Complex product you are using.
2. Atopic-Telmesteine™: Information on this specific ingredient was not available in the database. Please ensure you follow the supplier's recommended usage rate and mixing instructions for this component.
3. Preservation: While 1,2 Hexanediol offers some preservative boosting properties, a water-based formula like this is susceptible to microbial growth. It is highly recommended to include a broad-spectrum preservative system to ensure the safety and longevity of your serum, especially since it contains ingredients like water and humectants that can support microbial life.
4. pH Level: Vitamin B12 is sensitive to pH and is most stable between 4.0 and 6.5. You should check the final pH of your serum and adjust it if necessary to ensure the Vitamin B12 remains effective.
5. Ingredient Compatibility: Vitamin B12 is noted as being sensitive to other vitamins like Vitamin C and other B vitamins. Ensure that Atopic-Telmesteine™ or any other ingredients you might add later do not negatively impact the stability of Vitamin B12.

Mixing Steps

Your proposed mixing steps (combining 1-7, then adding 8) are generally appropriate for using Satin Cream Maker™ to create an emulsion with a silicone phase. Satin Cream Maker™ is added to the water phase, and then the oil/silicone phase is added while mixing. Ensure that temperature-sensitive ingredients like MOIST72™ and Vitamin B12 are added at temperatures below 40°C, ideally towards the end of the mixing process before adding Cyclomethicone or after the emulsion has formed and cooled down.

Expected Texture

Based on the ingredients, particularly the emulsified Cyclomethicone and the Ceramide Complex (Ceracare™ Liposome-3 is described as a cloudy liquid), the resulting serum is likely to have a cloudy or milky appearance rather than being completely clear. It should have a light, soft, and smooth texture due to the Satin Cream Maker™ and Cyclomethicone.

In summary, your formula is a good starting point with beneficial ingredients for your skin concerns. Consider adjusting the Ceramide Complex concentration, adding a preservative, checking the pH, and verifying the details of Atopic-Telmesteine™ for optimal results and safety.
