Formulation Suggestions for Oily, Acne-Prone Skin with Large Pores and Some Wrinkles

Based on your skin type and requests for a sunscreen+BB cream and a deeply cleansing face wash gel, here are some ingredient suggestions.

Limitation: Please note that I cannot provide exact, ready-to-use formulations with precise percentages. The information below is based on the properties and typical usage ranges of individual ingredients. Developing a stable and effective formulation requires laboratory testing and adjustment.

1. Sunscreen with BB Properties

For a sunscreen with BB properties suitable for your skin type, consider these key ingredients:

• Cyclopentasiloxane (Low-Odor Cyclomethicone): A lightweight, fast-evaporating silicone that helps the product spread easily, feels non-greasy, and leaves a soft, smooth feel on the skin. Suitable for oily skin. Can be used at 1-20%.
• Titanium Dioxide Nanosil and Zinc Oxide (20nm, Triethoxycaprylylsilane Coated): Nano-sized physical UV filters that provide good protection against UVA/UVB rays and cause less white cast compared to larger particles. Zinc Oxide is particularly good for long-wave UVA protection. Using both is recommended for broad-spectrum protection. Each can be used at 1-25%.
• BB Micro Silk™: A spherical powder that helps blur wrinkles and pores, providing a soft-focus effect and silky smoothness. It can also help absorb some oil. Suitable for use in BB creams or foundations. Can be used at 3-10% (6-7% recommended).

Formulation Approach:
These ingredients disperse well in oil or silicone bases. You can use Cyclopentasiloxane as a primary base along with the physical UV filters and BB Micro Silk™ to achieve a lightweight texture that provides coverage and blurs imperfections. Example approaches from the BB Micro Silk™ description include using it in a silicone base (e.g., Cyclomethicone 30%, Dimethicone 20%, Silicone Gel Base 40%, BB Micro Silk™ 10%) or a cream base.

2. Deeply Cleansing Face Wash Gel

For a face wash gel focused on deep cleansing, suitable for oily and acne-prone skin, choose effective surfactants and potentially add ingredients to address acne and pores:

• Surfactants:
  • Sodium Cocoyl Glycinate: A mild, amino acid-derived surfactant that produces rich lather, cleanses well, and helps keep the skin moisturized after washing. Can be used at 5-40%.
  • Clarify-Wash™ 35 Liquid (Sodium C14-16 Olefin Sulfonate 35%): A high-efficiency detergent for strong cleansing and lathering, suitable for clarifying formulas like those for oily or sweaty skin. Can be irritating at high concentrations. It has a high pH (8-9), so the final formula's pH should be adjusted to 5-6 for skin compatibility. Can be used at 5-35%.
• Thickener/Gelling Agent:
  • ThickClean™ (Acrylates Copolymer): A gelling/thickening agent for liquid soaps and shampoos. It helps create a clear gel texture and suspend insoluble particles. Works well in the pH range of 4-6.
• Optional Ingredient for Acne and Pores:
  • Salicylic Acid (BHA): Helps exfoliate skin cells, dissolve pore blockages, and has antiseptic properties. For rinse-off products, choose water-soluble forms like Encapsulated Salicylic Acid (Liquid, Timed-Release, Wash-Off) or Liquid Salicylic Acid (40% Active Salicylic, Cationic For Wash-Off) to ensure effectiveness in a wash-off formula. Use at concentrations permitted by regulations (up to 3% for rinse-off products).

Formulation Approach:
Combine the primary surfactant(s) with water, then add the gelling agent and any optional ingredients like Salicylic Acid. Adjust the final pH to be skin-friendly (around 5.5) and suitable for the chosen ingredients.

Please Remember: Determining exact percentages for a formulation requires experimental testing to ensure stability, desired texture, and performance. The information above provides guidance on suitable ingredients and their typical usage ranges.
