Suggested 50ml Serum Formula for Oily, Acne-Prone, Sensitive Skin

This formula is designed to be a lightweight, water-based serum.

Ingredients:

• Distilled or Deionized Water: 43.75 ml (approximately 43.75 g)
• Safe-B3™ (Vitamin B3, Niacinamide): 2.5 g (5%)
• Tranexamic Acid (Trans-White™): 1.5 g (3%)
• ActiveRelease™ Salicylic Acid: 1.25 g (2.5%)
• ActiveRelease™ Centella Asiatica: 0.5 g (1%)
• Mild Preserved™ COS: 0.5 g (1%)

Total: Approximately 50 g / 50 ml

Ingredient Benefits:

• Safe-B3™ (Niacinamide): Helps reduce oiliness, minimize pores, fade dark spots and redness, strengthen the skin barrier, and has anti-inflammatory properties, making it excellent for acne-prone and sensitive skin.
• Tranexamic Acid (Trans-White™): Specifically targets dark spots and hyperpigmentation, helping to even out skin tone.
• ActiveRelease™ Salicylic Acid: A gentle, water-soluble form of BHA that helps exfoliate inside pores, dissolving clogged pores and treating acne. The timed-release makes it less irritating.
• ActiveRelease™ Centella Asiatica: Provides strong anti-inflammatory and anti-irritant benefits, soothes the skin, and supports wound healing, which is great for sensitive and acne-inflamed skin.
• Mild Preserved™ COS: A broad-spectrum, water-soluble preservative suitable for sensitive skin and effective in the required pH range.

How to Make (50ml):

1. Weigh the Distilled or Deionized Water into a clean beaker or container.
2. Add Safe-B3™ (Niacinamide), Tranexamic Acid, and ActiveRelease™ Salicylic Acid powders to the water. Stir gently until fully dissolved. You can gently warm the water (up to 40-45°C) to help the powders dissolve faster, but avoid prolonged heating.
3. Add ActiveRelease™ Centella Asiatica liquid and stir to combine.
4. Add Mild Preserved™ COS and stir until evenly mixed.
5. Check the pH of the mixture. For optimal effectiveness and gentleness, the pH should ideally be between 4.0 and 6.0. If needed, you can adjust the pH using a very small amount of a mild acid solution (like Lactic Acid) or a mild base solution (like Triethanolamine).
6. Once the pH is adjusted and the mixture is uniform, transfer the serum into a clean bottle, preferably with a dropper or pump.

Usage:

Apply a few drops to clean, dry skin after cleansing, morning and night. Follow with a lightweight, non-comedogenic moisturizer if needed (though with oily skin, you might find this serum is enough hydration). Always use sunscreen during the day.

Important Notes:

• Start with a patch test on a small area of skin to check for any reaction, especially since you have sensitive skin.
• This formula is water-based and should feel light and absorb quickly. Avoid adding oils or heavy moisturizers to keep the texture light.
• Store the serum in a cool, dark place.
