looksmaxxing for cheap

cannot afford laneige lip masks or snail mucin :( i’m trying to get skinnier already but i can’t buy any new clothes and all my jeans hang off of me in a really unflattering way (btw does anyone else have this issue with h&m denims, they fit perfectly in store but idk what it is with the fabric, it expands when i wear it until it’s 2 sizes bigger and then shrinks back down to its original size when freshly washed). anyone have any ideas?
