Day Cream Formula Adjustment for Combination Skin\n\Based on your day cream formula and description of your skin type (combination, dry cheeks, oily T-zone with blackheads, dehydration, makeup not lasting), here are some suggested adjustments to your formula, incorporating the previous staff recommendations:\n\nYour skin sounds like it would benefit from balancing hydration without feeling heavy or greasy, especially in the T-zone. The original formula has good moisturizing ingredients, but some adjustments can help improve the texture and address the combination skin concerns more effectively.\n\n## Suggested Revised Formula\n\nHere is a suggested modification to your formula, taking into account the staff's advice to reduce stickiness and add skin-strengthening ingredients:\n\n* Oil Phase (Total 15%)\n * Sweet Almond Oil 5%\n * Rosehip oil 5%\n * Argan Oil 5%\n\n* Water Phase (Total ~80%)\n * Water ~52% (Adjust to reach 100% total)\n * Vit B5 (Panthenol) 2% (Reduced from 3% to minimize potential stickiness)\n * MOIST72 2% (Reduced from 3% to minimize potential stickiness)\n * Water lock 2%\n * Repair Activator 9% (Reduced from 12% as 9-10% is still a high and effective level)\n * Double Hyaluron Liquid 8%\n * Alpha Arbutin 2%\n * Safe-B3 (Vitamin B3, Niacinamide) 3% (Added to help strengthen skin barrier, reduce oiliness/pores, and improve tone)\n\n* Preserver (Total 4%)\n * Phenoxyethanol SA 1%\n * 1,2-Hexanediol 3%\n\n* Emulsifier (Total 1%)\n * Satin Mousse 1%\n\nTotal: 100%\n\n## Explanation of Changes\n\n* Reduced Vitamin B5 and MOIST72: While excellent for hydration, using them at 3% each can sometimes lead to a slightly sticky feel, which might contribute to makeup not lasting well on oily areas. Reducing them to 2% each still provides significant hydration benefits without the potential for excessive tackiness.\n* Reduced Repair Activator: 12% is a very high concentration. Reducing it to 9% or 10% still provides strong DNA repair and skin barrier support benefits, as suggested by the staff, while allowing room for other beneficial ingredients.\n* Added Safe-B3 (Niacinamide): This is a key addition for combination skin. Safe-B3 helps improve the skin barrier function, which is beneficial for the dry areas and helps reduce water loss (addressing dehydration). It also helps regulate sebum production, minimize the appearance of pores, and can help with blackheads in the oily T-zone. A concentration of 3-5% is effective for these benefits.\n\n## Additional Considerations\n\nIf you experience skin irritation or sensitivity, especially in the oily areas, ingredients like Atopi-Telmesteine or Palmitamide MEA could be considered. These ingredients are known for their anti-inflammatory and soothing properties, which can help calm irritated skin. If you wish to add these, you would need to adjust the percentages of other water-phase ingredients to maintain the total formula percentage.\n\nThis revised formula aims to provide ample hydration and skin repair while improving the texture for better wear on combination skin, addressing both the dry and oily concerns.
