1. Avoid applying eyeshadow powder heavily around the eyes.
Especially in hot weather when sweat increases, perspiration can push eyeshadow into the eyes, damaging the visual organs. Rubbing your eyes with your hands further risks introducing bacteria, potentially leading to trachoma or pink eye.
2. Avoid applying face masks over eyebrows and eyelashes.
When the mask adheres to these areas, removing it may pull out eyebrows and eyelashes.
3. Avoid applying makeup so heavily that your face appears pale and bluish.
Using oily cosmetics followed by a layer of powder to achieve a pale, bluish complexion prevents UV rays from being absorbed, hindering vitamin D production in the body.
4. Avoid sharing others' cosmetics
Cosmetics can transmit diseases. Never use someone else's makeup, and never lend your own cosmetics to others.
5. Avoid excessive pressure when exfoliating
During hot weather, enlarged pores and delicate skin make harsh scrubbing prone to damage from exfoliants' abrasive particles. Combined with sun exposure, this can worsen skin roughness.
6. Avoid constant powder touch-ups
Constantly reapplying powder throughout the day—layering blush over blush—creates unsightly patches. The nose especially darkens from the continuous buildup of oil and powder.
7. Avoid applying perfume directly to the face
Sunlight can trigger chemical reactions on perfumed skin, causing redness, swelling, and stinging. Severe cases may develop into dermatitis.
8. Avoid plucking eyebrows with makeup
Plucking eyebrows while wearing makeup creates a barren appearance. Medically, plucking not only damages physiological functions but also risks local infections by disrupting hair follicles and irritating the skin with cosmetic pigments.
9. Avoid excessive lipstick use
Lipstick oils can penetrate skin and attract airborne dust, metal particles, and pathogens. When broken down by saliva, harmful bacteria may enter the mouth, potentially causing "lip allergies."
10. Avoid sticking to one foundation shade
Foundation that is too dark or too light for your skin tone can ruin your appearance. Therefore, keep several shades on hand and adjust them as your skin tone changes with the seasons.
