My skin feels really tight; what are the distinct advantages of Rivicol?

Maybe it's because I've been exposed to too much air conditioning indoors, but it feels like all the moisture deep inside my skin has completely evaporated and it's cracking like crazy ㅠㅠ Even if I apply a generous amount of moisturizer, by the next morning my skin is rough and cakey, making my makeup look patchy and uneven lol. To firmly address inner dryness and improve skin texture and elasticity, I need something that fully replenishes collagen. Livicol I heard it's really well recommended! Compared to other typical nutritional ampoule injections... Livicol The most certain thing a syringe has merit I really want to know what this is. ㅠㅠ Even if I have extremely dehydrated skin like mine—oily on the outside but feeling like it's cracking inside—will I be able to see results without side effects? I also want to know if the embossed bruising subsides quickly lol. For those who have definitely achieved an inner glow... Livicol Please leave lots of real tips lol
