Recommended Lotion Formula for Very Dry, Easily Irritated Skin (100g)

Okay, I understand you are looking for a body lotion formulation for very dry, easily irritated skin prone to skin diseases, aiming for moisture, brightening, and reduced irritation. You've provided an initial formula and received feedback suggesting a revised formula that might be more suitable for your sensitive skin type.

Based on your skin concerns (very dry, easily irritated, prone to skin diseases) and the feedback you've received, the original formula contains ingredients like Sodium Lactate, Urea, and Natural PHA (Gluconolactone). While these are excellent humectants and can help with skin texture and mild exfoliation, their exfoliating action might be too stimulating for highly sensitive or compromised skin. Additionally, fragrance is a common irritant for sensitive skin.

The alternative formula suggested appears to be a better approach for your skin type, focusing on intense moisturization, barrier support, and soothing properties while minimizing potential irritants. This formula includes:

• Shea Butter: A rich emollient that provides intense moisture and helps support the skin barrier.
• MOIST24: A humectant that helps retain moisture in the skin throughout the day and can improve formula texture.
• Rhamnose: Known for its soothing and anti-inflammatory properties, helping to calm irritated skin.
• Vitamin B5 (Panthenol): A well-known ingredient for its moisturizing, soothing, and skin barrier repairing benefits.
• GlucoBright (N-Acetyl-D-glucosamine): Works with Niacinamide for brightening and can also help increase skin hydration by stimulating hyaluronic acid production. It offers very mild exfoliation compared to AHAs/BHAs.
• Safe-B3 (Vitamin B3, Niacinamide): Improves skin barrier function, reduces redness and hyperpigmentation, and has anti-inflammatory properties, making it excellent for sensitive skin.
• Magnolia Extract (Magnolol, Honokiol): An extract known for its strong anti-irritant and anti-inflammatory effects.
• Light Cream Maker: An emulsifier to create the lotion texture.
• Mild Preserved: A broad-spectrum preservative suitable for sensitive skin, replacing Phenoxyethanol which might be too harsh.

Regarding your concern about mixing Shea Butter, it is true that incorporating solid butters like Shea Butter typically requires a hot process. This involves heating the oil phase (containing the Shea Butter and emulsifier) and the water phase separately to a temperature where the butter is fully melted (around 60-70°C for Shea Butter), then combining and mixing them to form an emulsion as they cool. While it's an extra step compared to cold-process formulations, it's a standard technique and achievable for beginners with careful measurement and consistent stirring or blending during the cooling phase.

To scale the formula to a different batch size, such as 300g, you simply multiply the percentage of each ingredient by the desired total weight (e.g., for 300g, multiply each percentage by 3).

Here is the recommended formula based on the suggestions, adjusted to 100g:

• Water: 65.5%
• Shea Butter: 15%
• MOIST24: 5%
• Rhamnose: 2%
• Vitamin B5 (Panthenol): 3%
• GlucoBright (N-Acetyl-D-glucosamine): 4%
• Safe-B3 (Vitamin B3, Niacinamide): 2%
• Magnolia Extract (Magnolol, Honokiol): 1%
• Light Cream Maker: 1.5%
• Mild Preserved: 1%

This formula prioritizes intense hydration, skin barrier repair, and soothing properties, making it more suitable for your skin type compared to the original formula which included more potent exfoliants and fragrance.
