SUNSCREEN
Background and Date of approval SUNSCREEN
Sunscreen was initially approved by the U.S. FDA in August 1978 as an over-the-counter medication.Â
In the year 2019, the FDA proposed new rules to update sunscreen regulations, including changes to active ingredients, maximum SPF levels, and labelling requirements.
Uses of SUNSCREEN
Sunscreen is essential for protecting the skin from harmful UV radiation, which can lead to various skin issues. Regular use of sunscreen offers several benefits, including:
- Prevents sunburn by blocking harmful UVB rays.
- Reduces the risk of skin cancer by protecting against UV radiation.
- Prevents premature ageing of the skin by shielding it from UVA rays.
- Prevents skin damage such as sunspots, wrinkles, and pigmentation.
- Provides broad-spectrum protection against both UVA and UVB rays.
- Protects sensitive skin from UV-induced irritation and inflammation.
- Helps maintain even skin tone by reducing the risk of pigmentation.
How is SUNSCREEN administered?
Apply a generous amount of sunscreen to all exposed areas of your skin 15-30 minutes before sun exposure, allowing it to absorb and provide full protection. Massage it evenly into your skin, ensuring you cover areas like the face, ears, neck, and hands. Re-apply every two hours or more frequently if you swim or sweat. Don’t forget places like the back of your legs or feet.

- Do not use on broken or irritated skin: Sunscreen may cause further irritation or discomfort on damaged skin.
- Keep out of reach of children: Some sunscreens may be harmful if swallowed.
- Check for allergies: Always do a patch test before using new sunscreen to avoid allergic reactions.
- Use in conjunction with other sun protection: Sunscreen alone may not provide complete protection. Wear protective clothing, seek shade, and avoid prolonged sun exposure.
Precautions
It is generally safe to use sunscreen, but it is important to apply it correctly for maximum effectiveness. Apply a generous amount to all exposed skin 15-30 minutes before sun exposure, allowing it to absorb properly. Re-apply every two hours or more often if swimming or sweating. Avoid contact with the eyes and rinse immediately with water if it gets into them.Â
Always check the expiration date to ensure the sunscreen is still effective. Choose a sunscreen suited for your skin type and perform a patch test to check for any allergic reactions. Remember, sunscreen is just one part of sun protection, so also wear protective clothing, seek shade, and avoid prolonged sun exposure.
Word of Advice
Always apply sunscreen generously to all exposed skin areas at least 15-30 minutes before going outdoors. Reapply every two hours, or more often if sweating or swimming, to maintain continuous protection. Follow the storage instructions to keep the product in optimal condition. If you experience any irritation or discomfort, stop using it and consult a healthcare professional.
Frequently Asked Questions

Why is sunscreen important?
Sunscreen is important because it protects the skin from harmful UV radiation, which can cause sunburn, premature ageing, and increase the risk of skin cancer. Regular use helps maintain healthy skin by preventing UV damage.
Q2.
Is sunscreen good to wear every day?
Yes, wearing sunscreen every day is important for protecting your skin. It shields against harmful UV rays, which can cause sunburn, premature ageing, and increase the risk of skin cancer. Even on cloudy days or indoors, UV radiation can still affect your skin. Consistent use promotes long-term skin health and prevents damage.
Q3.

Sunscreen cannot remove a tan, but it helps prevent further darkening by protecting the skin from UV exposure. It can also prevent the tan from becoming more pronounced or leading to additional skin damage.
Q4.
What is the best sunscreen in use?

Q5.
How do I choose my sunscreen?
Choose a sunscreen with broad-spectrum protection to block both UVA and UVB rays. Opt for an SPF of 30 or higher for effective coverage. Consider your skin type; mineral sunscreens are ideal for sensitive skin, while chemical sunscreens may be better for other types.
