Toner Formulation for Normal to Oily T-Zone Skin (Focus on Brightening, Pores, Acne, Sensitive Skin)

For normal skin with an oily T-zone that is concerned with brightening, pore appearance, acne, and sensitivity, you can select ingredients with specific properties to create a toner. Here are some interesting ingredients:

• For Brightening:
  • Tranexamic Acid (Trans-White™) helps reduce melanin production, suitable for dull skin and acne marks.
• For Oil Control, Pore Tightening, and Acne Reduction:
  • Zinc PCA helps reduce oiliness, accelerates wound healing (e.g., acne scars), and reduces acne inflammation.
  • Sebum-Reg™ (Capryloyl Glycine) helps control oiliness and inhibits P.acnes bacteria that cause acne.
  • Pep®-Acne (Oligopeptide-10 Anti-microbial Peptide) is a peptide specifically targeting acne bacteria, suitable for acne problems.
• For Soothing Sensitive Skin and Reducing Irritation:
  • Licorice Extract helps reduce inflammation, redness from acne, and irritation.
  • Portulaca Extract helps reduce skin irritation.

Example Toner Formula (Adjust concentrations as appropriate for your needs):

• Distilled Water or Floral Water: Approx. 80-90%
• Tranexamic Acid (Trans-White™): 1-3%
• Zinc PCA: 0.5-1%
• Sebum-Reg™: 1-2%
• Pep®-Acne: 5%
• Licorice Extract: 0.5-1%
• Portulaca Extract: 0.1-0.5%
• Butylene Glycol (helps moisturize and acts as a solvent): 3-5% (can be adjusted down if other ingredients already contain Butylene Glycol)
• Preservative: According to manufacturer's recommendation (essential for water-based formulas)
• pH Adjuster (e.g., Triethanolamine, Citric Acid or Lactic Acid): Small amount for pH adjustment

Mixing Instructions:

1. Prepare a portion of the distilled water or floral water (approx. 10-20% of the total formula). Adjust the pH slightly above 7 (using a small amount of Triethanolamine). Gradually add Sebum-Reg™ and stir or mix until clear.
2. In another container, prepare the remaining distilled water or floral water. Dissolve Tranexamic Acid and Zinc PCA. Stir until dissolved.
3. Slowly combine the mixture from step 1 with the mixture from step 2. Stir well.
4. Add Pep®-Acne, Licorice Extract, Portulaca Extract, and Butylene Glycol. Stir gently to combine, avoiding high heat.
5. Add the preservative according to the recommended rate. Stir to combine.
6. Measure the pH of the formula. It should be in the range of 4-6 for optimal effectiveness of Zinc PCA and Sebum-Reg™. If the pH is higher than 6, gradually add a pH adjuster (e.g., Citric Acid or Lactic Acid) little by little, stirring and measuring the pH until the desired value is reached.
7. Pour into a clean container.

Precautions:

• Always test the product on a small area of skin before applying to the entire face, especially for sensitive skin.
• Adjust ingredient percentages based on your skin condition and individual response.
• Using Tranexamic Acid at concentrations up to 3% is considered cosmetics. Higher concentrations require registration as a medicine.
