Serum formulation for sensitive skin, seborrheic dermatitis, dryness, and irritation

Question

I am looking for a serum formulation to address my skin concerns, which include oily but dry skin, irritation, redness, seborrheic dermatitis, and fine lines. I need a formula that is suitable for these issues. Could you provide a detailed formula, including the percentage of each ingredient, mixing instructions, and recommended usage? I am also interested in whether the 'ready to use' service is available for such a formula and if certain ingredients like Ceramide Complex are currently in stock.

Answer

Based on the conversation, here is a summary of the recommended formula and mixing instructions for your skin concerns (oily but dry, irritated, red, seborrheic dermatitis, fine lines):

The final proposed formula, incorporating the adjustments discussed (replacing Ceramide Complex with Sea Kelp and avoiding Hydrolyzed Soy Protein), is approximately:

  • (Oat) Beta Glucan 2%
  • Ectoin 2%
  • Homeostatine 5%
  • Allantoin 0.3% (Note: There was a mention of a potential typo and it perhaps should be 3%, but 0.3% was listed in the final proposed formula)
  • Panthenol (pro vit B5) 5%
  • Natural Moisturizing Amino Acid 5%
  • Sea Kelp (percentage not explicitly stated, but assumed to replace Ceramide Complex, which was 8%)
  • Water (adjusted to make total 100%, e.g., if Sea Kelp is 8% and Allantoin is 0.3%, water would be 72.7%)

Mixing Instructions:

  1. Heat the water to 60°C.
  2. Add Oat Beta Glucan and stir until completely dissolved. Let the mixture cool down.
  3. Add Allantoin, Ectoin, Panthenol (pro vit B5), Natural Moisturizing Amino Acid, and Sea Kelp to the cooled water mixture. Stir until all ingredients are dissolved.
  4. Add Homeostatine and stir to combine.
  5. The pH of the final mixture is expected to be within the desired range (4.0-6.5) naturally, so pH adjustment is likely not needed unless you test it and find it outside this range.
  6. (Optional) If you prefer a thicker consistency than a watery serum, you can add Xanthan Gum at about 0.3% to create a slight gel texture.

Usage Recommendations:

  • Use the serum twice a day (morning and evening).
  • You can use it as a spray or apply it like a lotion. It will be quite liquid unless you add a thickener like Xanthan Gum.
  • This formula can be used around the eye area to help with dryness.
  • In the morning, apply sunscreen after the serum, especially since your skin is sensitive to the sun.
  • Focus on using this formula first to help balance and strengthen your skin before incorporating other creams or products you already own.

Regarding the "ready to use" service and the availability of Ceramide Complex, the conversation indicated that the "ready to use" status for this specific formula needed confirmation from staff, and Ceramide Complex has been temporarily discontinued due to its short shelf life and high cost.

Please try the formula and provide feedback so the team can help you make further adjustments if needed.
