Skincare for Oily, Acne-Prone Skin with Whitening Needs

For slightly oily skin with inflammatory and clogged acne that also needs whitening and a non-greasy feel, a combination of active ingredients targeting these concerns in a light, easily absorbed base like a serum or light lotion would be beneficial.

Key ingredients to consider include:

• Niacinamide (Safe-B3): Excellent for reducing oiliness, minimizing pores, strengthening the skin barrier, and reducing redness and post-inflammatory hyperpigmentation (dark spots left by acne). It also has anti-inflammatory properties which can help with inflammatory acne. A concentration of around 5% is effective.
• Alpha Arbutin: A well-known skin brightening agent that works by inhibiting melanin production, helping to reduce dark spots and improve overall skin tone for a more radiant complexion. A concentration of 2% is commonly used for whitening.
• Liquid Azelaic™ (Potassium Azeloyl Diglycinate): This water-soluble derivative of Azelaic Acid is effective in reducing oiliness, preventing clogged pores, and has antibacterial properties against acne-causing bacteria. It also helps to brighten the skin and fade dark spots. It can be used at concentrations of 5-10%.
• Pep®-Acne (Oligopeptide-10): An anti-microbial peptide that specifically targets acne-causing bacteria, making it a good addition for treating inflammatory acne. It is typically used at 5%.
• Actin AC: A comprehensive ingredient offering multiple benefits for acne-prone skin, including sebum regulation, anti-inflammatory effects, reduction of PIH, and antibacterial action. It is used at 2-4%.

Other ingredients from your list that can complement these actives include:

• Allantoin: Known for its soothing and skin-healing properties, which can help calm irritated skin and support recovery from acne.
• N-acetyl glucosamine: Works synergistically with Niacinamide for improved skin brightening and also provides hydration.
• WhiteCumin™ 2x (Tetrahydrocurcuminoids): Offers antioxidant and anti-inflammatory benefits, and can contribute to skin brightening.
• Soy Extract: Can provide antioxidant and soothing benefits.
• PE-1 Aqua: A penetration enhancer that helps the active ingredients absorb better into the skin without feeling heavy.

A formulation combining ingredients like Niacinamide, Alpha Arbutin, and Liquid Azelaic in a light, water-based serum or lotion would target whitening, acne, and oiliness effectively while providing a non-greasy feel. Adding Pep®-Acne or Actin AC could further enhance the anti-acne efficacy. Ensure the final product has a suitable pH (generally between 4.0-6.0 for optimal stability and efficacy of these actives).
