Okay, I understand you have very dry body skin and are looking for a professional formulation that provides high moisture without being sticky, along with a whitening effect. You've tried a previous formula that didn't work well and made your skin feel drier.

The staff has reviewed your situation and the formula you tried. They have suggested an adjustment to your previous formula, increasing the concentration of moisturizing ingredients like Rose hip oil, Shea butter, B5, and Natto, and adding MOIST72™ to specifically address the extreme dryness you are experiencing, based on your feedback that the previous formula made your skin drier.

The staff's latest suggestion focuses on optimizing the moisture level based on your specific feedback. However, your original request also included a whitening effect, which was not explicitly addressed in the staff's suggested modification.

To meet both your requirements for intense moisture and whitening, I propose building upon the staff's suggested moisturizing base by adding effective whitening ingredients.

Here is a proposed formula combining the staff's recommended adjustments for dryness with added whitening agents:

Body Lotion Formula for Very Dry Skin + Whitening

• Rose hip oil: 10% (Helps nourish very dry skin)
• Shea butter: 10% (Provides high moisture)
• B5 (Panthenol): 10% (Helps soothe and strengthen skin barrier)
• Natto Gum: 10% (Provides moisture and helps soften skin)
• MOIST72™: 3% (Intense, long-lasting moisturizing agent)
• Water lock: 2% (Helps retain moisture)
• Niacinamide (Vitamin B3): 4% (Helps with brightening, reducing dark spots, and strengthening skin barrier)
• Alpha Arbutin: 2% (Helps reduce dark spots and dullness for brighter skin)
• Light Cream Maker: 1% (Emulsifier, creates a light, non-sticky texture)
• Water: Adjust to 100%

Ingredient Explanation:

• High Moisture Group: Rose hip oil, Shea butter, B5, Natto Gum, MOIST72™, Water lock. The concentrations of these ingredients have been increased as recommended by the staff to focus on restoring and providing intense moisture to extremely dry skin.
• Whitening Group: Niacinamide and Alpha Arbutin are popular ingredients used to help brighten skin, reduce dark spots, and even out skin tone. Using them together can enhance their effectiveness.
• Texture Group: Light Cream Maker helps create a light, easily absorbed cream texture, reducing stickiness even with high moisturizing ingredients.

Additional Recommendations:

• This formula focuses on both high moisture and whitening. Please mix carefully according to the recommended percentages.
• Always patch test the product on a small area of skin before applying it all over the body to observe your skin's reaction.
• Seeing results regarding skin brightening takes time and consistent use.
• If the texture feels too heavy after use, you might consider slightly reducing the Light Cream Maker or adjusting the ratio of water to oil/butter ingredients, but you should maintain the percentages of the key active ingredients (B5, Natto, MOIST72, Niacinamide, Alpha Arbutin).
• Working in an air-conditioned environment all day contributes to skin dryness. Applying body lotion regularly in the morning and before bed is very important.

This formula combines the staff's recommendations to address your very dry skin issue and adds whitening ingredients as you requested. I hope this is helpful and assists you in creating a product that works better for your skin.
