Anyone who feels their skin is dull while on a diet shake diet?

It's already quite late at night. I'm sitting on the bed wearing only sleep socks, but I can't sleep because my skin looks unusually dull in the mirror... It's already past 11:30. I think I'll have to slim down my diet a bit as the year-end approaches, so I'm drinking the same thing I drink every night. diet shake I started to worry about how it affected my skin. Maybe it's because I'm so sensitive to even the smallest changes, or maybe it's the heat from the heater, or maybe it's a lack of nutrition, but I couldn't help but keep a record. I've been taking pictures of my skin these past few days, and it definitely feels like my complexion has become duller. Honestly. diet shake I'm more curious about how the ingredients in a product contribute to skin elasticity than the calories themselves. Some products are full of protein, while others contain multivitamins. Do you have any questions? diet shake Do you consider your skin health when choosing the product I am drinking now? diet shake It tastes like grains, so it's delicious, but I'm worried it might have something to do with skin hydration. Even if I lose weight, I really want to avoid facial aging! For the next two weeks, I plan to keep a daily food diary and compare it to my skin's changes. If anyone else, like me, is sensitive to skin conditions while using this as a meal replacement, could you give me some advice? I have so many questions tonight...
