Serum Recommendation for Oily Skin with Melasma, Freckles, and Clogged Pores

Regarding your question about mixing Activated Resorcinol, this ingredient is oil-soluble and needs to be dissolved in an oil phase. In the context of the ingredients we've discussed, MSH White Absorb can be used as the oil phase to dissolve Activated Resorcinol before adding it to the rest of the formula.

Based on your skin type (oily, prone to clogged pores, melasma/freckles, sensitive to sun/heat) and preference for a non-sticky serum/gel texture, here is a refined formula combining effective ingredients:

Proposed Serum Formula:

• Silky Serum Base Plus: 20%
• Water: 48.5%
• MSH White Absorb: 5%
• Safe B3 (Niacinamide): 5%
• Fast Relief: 1%
• Moist 24: 1%
• Licorice Extract (Licochalcone): 0.5%
• Repair Activator: 10%
• Activated Resorcinol S: 3%
• Salicylic Acid EZ: 2% (Can increase up to 5% for night use if needed for clogged pores)
• Zinc PCA: 0.5%
• Tranexamic Acid: 2%
• Mild Preserved Eco: 1%

Mixing Instructions:
