Every time I look in the mirror, I desperately need the effects of an ampoule for skin elasticity. How do you all feel about it?

Time flies by so quickly as I get to work. When I wake up, it seems like the pillow marks take longer to disappear than before, and maybe because my skin is dry, I keep getting hangnails, which is really frustrating... I try to be careful and apply a lot of skin elasticity ampoule products in the morning and evening. But I'm worried because I don't feel any noticeable changes, so I'm not sure if I'm being too timid in my choices or if I chose the wrong products.

These days, with winter weather like this, the temperature difference between indoors and outdoors is so large that my skin feels so dry inside. I'm wondering if the elasticity ampoule I've been using isn't enough to moisturize and plump my skin. Is there anything I'm missing in my routine? Oh, come to think of it, I was so busy this morning that I forgot to take my vitamins again. They say you need to take care of your skin inside as well as out, but this damn forgetfulness is just making me worry more and more...

Do you have any recommendations for skin-firming ampoules that you've personally used and found effective? Or, if you have any tips of your own that are great for maintaining elasticity during the winter, please share them with us. I'm curious if it's just me or if other people have similar concerns around this time of year, especially since my skin tends to look sagging in the winter.
