Some companies write the expiration date of their sunscreens. But if an expiration date is not mentioned on the product, you can use it until three years of the purchase.
Does Sunscreen Expire?

But if the sunscreen expiry date is not mentioned, do not use it after three years of purchase. It will not be practical or might even cause harm to your skin.

These not only protect your skin against harm but also nourish and moisturize it. If you have sensitive skin, then physical sunscreen would be a better option for you.
How Much Sunscreen Should I Apply?
Sunscreens can be highly beneficial in protecting from the sun. But it will only be effective if applied correctly.

Hands, the back of the neck, and other exposed body parts should be covered with an even layer so they may not stand out and blend with your skin.
How to Apply Sunscreen on the Face?
Applying sunscreen on your face is easy. Take a little sunscreen in your hands and evenly distribute it on your face. Keep in mind that the layer should not be thin, which would come off easily, and also not too thick, which would cause irritation and sweating. Use it 15 mins before stepping out in the sun for best results.
