Reviewing Water-in-Oil Lotion Formula for Dry Skin and Whitening

Based on the formula you provided and your skin concerns (dryness, sun tan, need for moisturization without stickiness), and considering the staff's feedback, here is a review of your lotion formula:

Your formula includes several good ingredients for whitening (4MSK, Tranexamic Acid, Ethyl Ascorbic acid, Yeast Radiance™), moisturization (MOIST24, LipidSoft™ Lite, Water-Capsule), and skin repair/anti-aging (Ume Extract, Active Resveratrol™, Repair Activator). The total percentage is close to 100%.

The formula is mixable, but as the staff noted, there are a couple of points to consider:

1. Moisturization for Dry Skin: You are using a Water-in-Oil system (Water-Capsule) which is good for creating a moisturizing film. However, the staff suggested that the oil phase (LipidSoft™ Lite at 6%) might be too low or too light for significantly dry skin. To enhance moisturization, you might consider increasing the percentage of LipidSoft™ Lite or using a heavier oil. Be aware that using heavier oils or higher oil percentages might slightly increase the feeling of stickiness, which goes against your preference for a non-sticky feel. You may need to find a balance.
2. Hydrogenated Lecithin (Penetration Enhancer): The staff correctly pointed out that Hydrogenated Lecithin requires high-speed blending (1000-1500 rpm for 10-15 minutes) to disperse properly and function as a penetration enhancer. If you do not have access to a suitable high-speed blender, you should remove this ingredient from the formula. The staff suggested Reservoir-Tech as an alternative penetration enhancer that might be easier to incorporate without specialized equipment.

Overall, the formula is a good starting point. Adjusting the oil phase based on your skin's actual dryness level and ensuring you can properly incorporate the Hydrogenated Lecithin (or substituting it) are the key considerations.
