Men's Serum Formulation Feedback for Oily Skin & Pores

Subject: Feedback on Men's Serum Formulation for Oily Skin, Large Pores, Dullness, and Clogged Pores

Thank you for sharing your serum formulation for men's skin with concerns about oiliness, large pores, dullness, and clogged pores. Based on your formulation and the staff's feedback, here are some points and suggestions for adjustment:

1. Salicylic Acid (BHA): As the staff mentioned, the regular Salicylic Acid (ID 148) is not soluble in this type of water-based serum. It is highly recommended to replace it with Salicylic Acid EZ (ID 766) at the same concentration (2%) as it is designed for easy dissolution in water-based formulas.
2. pH Adjustment: Salicylic Acid is acidic. After incorporating Salicylic Acid EZ, it is crucial to measure the final pH of your serum and adjust it to the recommended range of 4.5-6. This range is optimal for the efficacy and stability of most ingredients in your formula and helps prevent skin irritation.
3. Oil Control & Pores: The staff's suggestion to add Safe-B3 (Niacinamide, ID 74) at 3-5% is excellent. Niacinamide is known to help regulate sebum production, improve the appearance of pores, and also offers brightening benefits, which aligns well with your goals. It will work synergistically with Zinc PCA (ID 252) and Vitamin B6 (ID 643).
4. Hydration for Oily Skin: Given the user has oily skin, the staff's recommendation to remove Double Hyaluron Liquid (ID 404) is appropriate. While hydration is important, oily skin types often require lighter hydration sources, and other ingredients might provide sufficient moisture without adding heaviness.
5. Preservative (Glydant): The staff noted they couldn't comment on Glydant (0.5%) without more information. Please verify that 0.5% is the correct and effective concentration for Glydant to adequately preserve your formula, especially considering the water base and active ingredients. Ensure it provides broad-spectrum protection.
6. Ingredient Delivery: Adding Reservoir-Tech (ID 1246) at around 3% as suggested by the staff is a good idea. This ingredient can help improve the penetration and sustained release of the active ingredients into the skin, potentially enhancing their effectiveness.
7. Other Ingredients: The other ingredients you included - Wrinkle-Lax™ (ID 1138), Lift-Now (ID 406), Alpha Arbutin (ID 68), Zinc PCA (ID 252), and Vitamin B6 (ID 643) - are suitable for addressing concerns like tightening, brightening, oil control, and pore appearance. Hydroxy Ethyl Cellulose (ID 336) is appropriate as a thickener.

Suggested Revised Formulation Adjustments:

• Replace Salicylic Acid (ID 148) with Salicylic Acid EZ (ID 766) at 2%.
• Add Safe-B3 (Niacinamide, ID 74) at 3-5%.
• Remove Double Hyaluron Liquid (ID 404).
• Add Reservoir-Tech (ID 1246) at 3%.
• Keep Wrinkle-Lax™ (ID 1138) 0.4%, Lift-Now (ID 406) 5%, Alpha Arbutin (ID 68) 2%, Zinc PCA (ID 252) 1%, Vitamin B6 (ID 643) 3%, Hydroxy Ethyl Cellulose (ID 336) 1.2%, Glydant 0.5%ไว้
• Adjust the percentage of Deionized Water (DI Water) accordingly to make the total 100%.
• Crucially, measure and adjust the final pH to 4.5-6.

This revised formula incorporates the staff's valuable feedback and targets the user's specific concerns more effectively, particularly regarding oiliness, pores, and clogged pores, while maintaining benefits for dullness and tightening.
