Simple Whitening Serum for Oily, Acne-Prone Skin

For oily and acne-prone skin that needs whitening, a simple water-based serum or gel can be effective. Here is a suggestion using ingredients known for their benefits in these areas:

• Azelaic Acid (Liquid Azelaic™): This ingredient is excellent for brightening skin, reducing dark spots, controlling oil production, and helping with acne. It is a water-soluble form that is gentler on the skin.
• Zinc PCA: Known for its ability to reduce skin oiliness, accelerate the healing of acne scars, and reduce acne inflammation.
• Hexylresorcinol AF: A potent water-soluble whitening agent that helps reduce dark spots and improve overall skin tone.

These ingredients can be combined in a suitable base (like a light serum or gel base) to create a multi-functional product targeting whitening, oil control, and acne concerns. Always follow recommended usage rates for each ingredient when formulating.
