Amulya Sunscreen Lotion

Yes it is good to use. But understand this. Any sunscreen will help upto certain extent only. There is no cream in the world that give 100% protection. So better cover the skin properly.

Use sunscreen with spf of 50. U can apply at home also. Windows and fluorescent bulbs can let through uv rays that can cause damage to your skin ? so unless you're in a windowless room with no light, your skin is receiving uv radiation.

It's ideal to select a sunscreen that blocks enough uv rays to adequately protect your skin type. Use the sun protection factor guide to help determine your skin type and appropriate spf. If you have very fair or sensitive skin, a history of skin cancer, or take photo-sensitizing medications, you may need a higher spf.

Yes you can use sunscreen. But first do skin test by applying on a small part on your arm. If no adverse reaction, you can use it.

No my field of expertise, but you can try with higher SPF (Sun Protecting Factor), trial and error the one that suits your skin.
