Night Cream Formulation for Acne-Prone Combination Skin

This formulation combines ingredients to target oiliness, acne, inflammation, and scarring, while incorporating the requested plankton extract.

Key Ingredients:

• Plankton Artemia Extract: This extract helps protect the skin, can increase collagen production, and supports overall skin health. It's included as per your request.
• Sebum-Reg™: Works to reduce skin oiliness by controlling the 5-alpha-reductase process, which can help reduce dandruff and P. acnes bacteria.
• Actin AC: A comprehensive anti-acne ingredient that regulates sebum, reduces inflammation and post-inflammatory hyperpigmentation (PIH), normalizes keratinization to prevent clogged pores, and reduces acne-causing bacteria.
• White Egg Enzyme (Acnezyme™): Contains Lysozyme, an enzyme that helps kill acne-causing bacteria (P. acnes).
• Licorice Extract: Known for its ability to reduce skin inflammation, redness from acne, irritation, and also helps control skin oiliness.
• Copper Peptide: Beneficial for addressing scars, including acne scars, and can help stimulate skin regeneration.

Formulation Considerations:

• Choose a lightweight cream or lotion base suitable for combination skin, avoiding heavy oils that could clog pores.
• Ensure the final pH of the formulation is within the recommended range for the active ingredients (e.g., Sebum-Reg™ works best at pH 4-6, Acnezyme™ at pH 4-7, Copper Peptide at pH 4.5-7.4, Plankton Artemia Extract at pH 4-6.5, Licorice Extract at pH 3.5-6.5, Actin AC at pH 3.5-5.5). A pH around 4.5-5.5 would be a good target range to balance the needs of most ingredients.
• Follow the specific mixing instructions for each ingredient, particularly regarding temperature sensitivity (e.g., avoid heat for Acnezyme™ and Plankton Artemia Extract, mix Copper Peptide in the final step below 40°C, mix Actin AC below 50°C or in the oil phase).
• Consider adding a chelating agent if using Actin AC to prevent issues with metal ions.
• Include a suitable preservative system to ensure product stability and safety.
