Moisturizers for Winter Lotion

Based on your question and the previous staff recommendation, both MOIST72 and WaterLock are suitable options to add extra moisture to your lotion formula for the winter.

• MOIST72 (Saccharide Isomerate): This ingredient is a plant-based sugar molecule that mimics the skin's natural moisturizing factor (NMF). It provides deep, long-lasting hydration, helping to keep your skin moisturized for up to 72 hours. It's excellent for improving overall skin hydration and reducing dryness.

• WaterLock (Polyquaternium-51): This ingredient works by forming a protective layer on the skin's surface, similar to the skin's natural phospholipids. This layer helps to prevent water loss from the skin (Transepidermal Water Loss - TEWL), keeping the skin hydrated. It also contributes to a smooth, non-sticky feel on the skin.

Both ingredients can be added at a recommended rate of 1-2% to your lotion formula. They are water-soluble and can be mixed into the water phase or added at the final step, depending on the specific instructions for each ingredient (MOIST72 is typically added in the final step below 40°C, while WaterLock can be mixed in water and tolerates heat).

Choosing between the two depends on your preference: MOIST72 focuses on boosting the skin's own hydration mechanisms, while WaterLock focuses on creating a barrier to lock in moisture and provide a smooth feel. You could also consider trying one first and then the other, or even a combination at lower percentages, to see which provides the best feel and hydration for your skin.

Remember to incorporate the chosen ingredient at the recommended usage rate to enhance the moisturizing properties of your lotion during the colder months.
