Answer

Here is a summary of the discussion and the final proposed formulas and mixing instructions:

Night Cream Formula (for face, whitening, normal to slightly dry skin, some freckles/acne):

Based on your revised list and the feedback, the formula you decided on is:

  • Glucosamine: 3% (Staff suggested up to 4%)
  • Vitamin B3: 2% (Staff suggested up to 4-5%, recommending 4% if concerned about flushing)
  • Green Tea Extract: 5%
  • Alpha Arbutin: 2%
  • Avocado Oil: 5% (Staff mentioned Rose Hip Oil could be more beneficial but is more expensive)
  • Bisabolol: 0.5%
  • Light Cream Maker: 1.5%
  • Phenoxyethanol: 1%
  • Sea Kelp Bioferment: 5%
  • Vitamin B5 (Panthenol): 5%
  • Distilled Water: Quantity Sufficient (QS) to 100%

Body Lotion Formula (for whitening):

Based on your revised list and the feedback, the formula you decided on is:

  • Sodium PCA: 5% (Staff suggested Natural Moisturizing Amino Acids as a better alternative)
  • Lactic Acid (AHA): 5%
  • Fractionated Coconut Oil (Caprylic/Capric Triglyceride): 5%
  • Vitamin B3: 2% (Staff suggested increasing to 4-5% for body lotion)
  • Glucosamine (N-acetyl-D): 4%
  • Aloe Vera Extract: 3%
  • Oil Free Titanium Dioxide Nano: 15%
  • Light Cream Maker: 1%
  • Phenoxyethanol: 1%
  • Distilled Water: Quantity Sufficient (QS) to 100%

Important Note on Body Lotion Formula: The staff (C7) strongly advised against using Lactic Acid (AHA) 5% in a formula containing Titanium Dioxide (which acts as a sunscreen) if the lotion is intended for daytime use. AHA exfoliates the skin, making it more sensitive to the sun. If you plan to use this lotion during the day, it is recommended to remove the Lactic Acid. If you want the exfoliation benefit, it's better to use AHA in a separate night-time product.

Mixing Instructions:

The mixing method you described was confirmed as correct:

  1. Separate the ingredients into a water phase and an oil phase.
  2. Add the Light Cream Maker to the oil phase and mix them together.
  3. Add the water phase into the oil phase and mix for no more than 5 minutes until the cream texture forms (white and pearlescent).
  4. Add Phenoxyethanol (preservative) and mix thoroughly to combine.

No heating was mentioned as necessary for the ingredients in these specific formulas.
