Analysis of Your Proposed Serum Formula

Thank you for providing your serum formula and explaining your skin concerns (clogged pores, dullness) and goals (clearer, brighter skin). You have a combination skin type.

Let's analyze the ingredients in your proposed formula:

• Cyclomethicone (20%) and Silicone Gel (5%): These silicones will give your serum a smooth, non-greasy feel, which is generally suitable for combination skin. The Silicone Gel you listed (High Gloss) might provide a shiny finish; a matte silicone gel could be an alternative if you prefer a less shiny look.
• Water (59.5%): This is the base of your water-based serum.
• B3 (Niacinamide) (4%): This is an excellent ingredient for your concerns. Niacinamide helps reduce excess oil, minimize pores, improve skin barrier function, and reduce redness and hyperpigmentation, contributing to brighter skin. 4% is an effective concentration.
• Indian Gooseberry Extract (3%): Known for its antioxidant properties and potential to help brighten skin tone.
• Centella Asiatica Extract (1%): A great addition for acne-prone skin. It has soothing, anti-inflammatory, and wound-healing properties that can help reduce redness and improve the appearance of acne marks.
• Mangosteen Extract (1%): Often used for its antioxidant and anti-inflammatory benefits.
• Apple Stem Cell (2.5%): Primarily used for anti-aging benefits, it may also contribute to skin renewal and a brighter appearance.
• Warp Cream Maker (4%): The function of this ingredient is unclear without specific product information. If it's an emulsifier or thickener, its compatibility with the other ingredients, especially the silicones, is important for formula stability.

Addressing Your Goals:

Your formula contains several ingredients beneficial for brightening and general skin health (Niacinamide, Indian Gooseberry, Centella Asiatica, Mangosteen, Apple Stem Cell). Niacinamide and Centella Asiatica are also helpful for managing some aspects of acne, like oiliness and inflammation.

However, the formula does not contain a key ingredient specifically for treating clogged pores (สิวอุดตัน), which you mentioned is a primary concern. As the staff suggested, Salicylic Acid (BHA) is highly effective for this purpose as it can penetrate oil within the pores and exfoliate from within, helping to unclog them.

Recommendations:

1. For Clogged Pores: We highly recommend following the staff's suggestion to use a separate product containing Salicylic Acid EZ as a targeted treatment for your clogged acne. The staff provided a sample BHA gel formula for this purpose, which you would apply and rinse off.
2. For Brightening and General Skin Health (Your Serum Formula): Your proposed serum formula is a good base for brightening and soothing. To improve it and ensure stability and safety:
   • Add a Preservative: Your formula is water-based and requires a preservative to prevent bacterial and fungal growth. Mild Preserved Eco is a suitable, gentle option, as suggested in the staff's BHA formula example. Add this at the recommended rate (typically 1-1.5%).
   • Consider Additional Soothing/Moisturizing: To complement the BHA treatment and reduce potential irritation, you could consider adding Panthenol (Vitamin B5) and/or Licorice Extract, as also suggested by the staff. These ingredients help soothe the skin and provide hydration.
   • Clarify "Warp Cream Maker": Ensure this ingredient is compatible with your formula and understand its function for stability.
   • Silicone Gel Choice: If you prefer a matte finish, consider using a silicone gel specifically described as "matte" instead of "High Gloss".

In summary, your proposed serum is a good leave-on treatment for brightening and soothing. For effective treatment of your clogged pores, a separate BHA product is essential, as recommended by the staff. Remember to include a preservative in your serum formula.
