Review of Gentle Facial Cleanser Formula

Here is a review of your proposed facial cleanser formula for sensitive, oily, acne-prone skin with large pores, dullness, dryness, and loss of firmness.

1. Suitability of Ingredients and Potential Interactions

The ingredients you have chosen are generally suitable for a gentle facial cleanser, particularly for sensitive and dry skin.

• AminoWash™ (Sodium Lauroyl Glutamate) and Lauryl Glucoside are gentle surfactants derived from natural sources, known for being less irritating than sulfates. They provide cleansing without stripping the skin's natural moisture barrier.
• Disodium EDTA is a chelating agent that helps improve formula stability by neutralizing metal ions in water. It is also noted to help prevent AminoWash™ from solidifying.
• 1,3-Propanediol and Glycerin are effective humectants that attract and retain moisture, helping to combat dryness.
• Lemon extract (Lemon Peel Bioferment) is included for its potential brightening and antioxidant properties, which can help with dullness.
• Double Hyaluron Liquid provides hydration to different layers of the skin, addressing dryness and potentially improving the appearance of firmness through plumping.

Based on the ingredients listed, there are no obvious incompatible combinations. However, the final pH of the formula is critical, especially for the efficacy of Lemon Peel Bioferment and to ensure the gentleness of Lauryl Glucoside, which has a high pH and requires adjustment.

2. Suitability for the Described Skin Problems

This formula is well-suited for:

• Sensitive Skin: The choice of gentle surfactants and the inclusion of humectants make this formula appropriate for sensitive skin.
• Lacks Moisture: Glycerin, 1,3-Propanediol, and Double Hyaluron provide good hydration.
• Dullness: Lemon extract can help improve skin radiance.

However, the formula is less targeted towards:

• Oily, Acne-Prone Skin, Large Pores: While cleansing is essential, this formula lacks active ingredients specifically aimed at reducing oil production, treating acne bacteria, or minimizing the appearance of pores.
• Loss of Firmness/Not Tight: While hydration from hyaluronic acid can temporarily improve skin's plumpness, the formula does not contain ingredients known for significant long-term firming effects.

3. Texture (Gel or Liquid for Whip Foam)

Given the ingredients, particularly the presence of water, liquid surfactants like Lauryl Glucoside, and thick liquids like Double Hyaluron Liquid and Glycerin, the resulting texture is likely to be a liquid or a thin gel. This consistency is suitable for creating a whip foam.

4. Additional Recommendations

• pH Adjustment: It is crucial to check and adjust the final pH of the formula to be in the range of 5-6, which is optimal for skin health and within the effective range for Lemon Peel Bioferment (pH 3.5-7). Lauryl Glucoside has a high pH and will require acidification using an ingredient like Citric Acid or Lactic Acid.
• Preservation: Ensure the formula has an effective broad-spectrum preservative system to prevent microbial growth, especially since it contains water and botanical extract. While Double Hyaluron Liquid contains a preservative, it might not be sufficient for the entire formula.
• Targeting Oily/Acne/Pore Concerns: If you want to address oiliness, acne, and large pores more effectively, consider adding ingredients like Niacinamide or a gentle BHA (like Salicylic Acid, keeping in mind pH requirements).
• Targeting Firming Concerns: For more pronounced firming benefits, you could explore adding peptides or other firming active ingredients.
• Ingredient Concentrations: The efficacy of the formula depends heavily on the concentration of each ingredient. Ensure the usage rates are appropriate for the desired performance and skin type.

This formula provides gentle cleansing and good hydration, making it suitable for sensitive and dry skin with dullness. To address the other concerns (oiliness, acne, pores, firmness), additional targeted active ingredients would be beneficial.
