Serum Formulation for Pore Tightening and Oil Control (50ml)

Based on your skin concerns (combination, acne-prone, oiliness, enlarged pores, dryness/peeling from Benzac), the previously recommended formulation is suitable. This serum aims to control oil, tighten pores, reduce inflammation, and promote clearer skin.

Here is the formulation for 50ml:

• Purified Water: 38.5 g
• Pro Polymer™: 0.5 g
• Vitamin B6 (Pyridoxine Hydrochloride): 1.5 g
• Pure MSM™ (Methylsulfonylmethane): 1.5 g
• Licorice Extract (Licochalcone A 1%, Water-Soluble): 0.5 g
• Zinc PCA: 0.5 g
• Safe-B3™ (Vitamin B3, Niacinamide): 2.5 g
• AcneBee: 2.5 g
• PE-1 Aqua: 1.5 g
• Phenoxyethanol SA (eq. Optiphen Plus): 0.5 g

Ingredient Benefits:

• Vitamin B6: Helps balance skin oiliness and tighten pores by reducing excess oil.
• Pure MSM™: Controls oil production and can help with exfoliation at higher concentrations (this formula uses 3% for oil control).
• Licorice Extract: Reduces skin inflammation, redness from acne, and irritation. Also helps control facial oil.
• Zinc PCA: Reduces skin oiliness, accelerates wound healing (like acne scars), stimulates collagen, and helps reduce acne breakouts.
• Safe-B3™ (Vitamin B3, Niacinamide): Reduces redness/hyperpigmentation, adds moisture by stimulating collagen and ceramide, strengthens the skin barrier, reduces oiliness, and is suitable for acne-prone skin.
• AcneBee: (This ingredient is included in the recommended formula, but specific details from its description are not available.)
• PE-1 Aqua: A penetration enhancer to help water-soluble ingredients absorb better into the skin.
• Pro Polymer™: A gel maker to create the serum texture. Note that Zinc PCA is an electrolyte and may require a slightly higher amount of Pro Polymer or specific mixing steps to achieve the desired gel consistency.
• Phenoxyethanol SA: A broad-spectrum preservative to protect the formulation.

Mixing Instructions:

1. Disperse Pro Polymer in the Purified Water. Stir slowly for 3-5 minutes until a smooth gel forms. Avoid high-speed blending. If using glycerin or propylene glycol (not in this specific formula, but general note from description), disperse Pro Polymer in that first before adding water. Allow the gel to fully hydrate, potentially leaving it for 1 day if needed for complete dissolution without high shear.
2. In a separate container, dissolve Vitamin B6, Pure MSM, Licorice Extract, Zinc PCA, Safe-B3, AcneBee, and PE-1 Aqua in a small amount of the remaining water. Note that Vitamin B6 is sensitive to heat and light, so mix without heat and avoid light exposure. Zinc PCA is best dissolved at pH 4-6. Vitamin B6 is acidic (pH 2-3) and an electrolyte, which might affect the gel.
3. Add the dissolved active ingredients mixture from step 2 to the gel base from step 1. Mix gently until uniform.
4. Add Phenoxyethanol SA to the mixture. Mix gently. Ensure the temperature is below 60°C when adding Phenoxyethanol SA.
5. Check and adjust the pH if necessary to be within the optimal range for the ingredients (e.g., Zinc PCA prefers 4-6, Vitamin B6 is stable at 2-6, Safe-B3 at 3-8, Licorice Extract at 3.5-6.5). Aim for a pH suitable for skin (typically 5.0-6.0).
6. Add the remaining Purified Water to reach the total weight of 50g. Mix thoroughly.
