1. Apply not enough sunscreen
Tip: It is important that you apply 2mg of sunscreen for every square inch of skin.
SPF (short for Sun Protection Factor) is an index that describes the degree of sunscreen that protects the skin against UVB rays that cause sunburn. If you apply 2mg of sunscreen per square inch of skin; Sunscreen with SPF 30 will block 96.7% of UVB rays. If you apply only half this amount, you will only block about half of UVB rays. So when applying sunscreen, you need to apply evenly and in a sufficient amount, not save.
2. Abusing spray sunscreens or bars
Tip: If possible, use topical sunscreen lotion (sunscreen lotion).

4. Think that sunscreen with a high SPF will last longer
Tip: Even if you reuse sunscreen with an SPF above 100; it's important to reapply often. A sunscreen with a higher SPF does not mean it lasts longer.
SPF only indicates the percentage of UVB rays blocked by sunscreen, not the time of protection. That is, a sunscreen with a higher SPF value will block more UVB rays and not mean any other effective time.
5. Use expired sunscreen
Tip: Sunscreen as well as other cosmetics, of course you should use before expiry. If your sunscreen does not have an expiration date, you should throw it away after 3 years.
