1- Mascara: If you’re not using it already, it makes a HUGE difference. Especially if you want your eyes to stand out as your best feature, it helps a whole lot. 100% underrated.
2- Relax your face: If you’re always frowning/have a rbf, you will always look unapproachable and rude. I used to this but I stopped and I noticed a huge difference!
3- Have some sort of routine: Whether its a serum you use every night, or a certain cleanser, have something you use for your face on a regular basis to treat any problem you have (hyperpigmentation, acne, etc)
Hope it helps!
