How To Choose The Best Sunscreen

There are a lot of different kinds of sunscreen products on the market now. With the deepening of people’s understanding of sunscreen, people’s demand for these products is also higher and higher. Why do we need sun protection? Just as plants need sunlight, so do we. More sun exposure can promote bone growth and help us grow taller. But the sun’s rays can be harmful to our skin.


Ultraviolet rays in sunlight are a major cause of skin damage. Be exposed for a long time below stronger ultraviolet ray, can damage our epidermal cell, promote the formation of pigment, as time passes, can discover to be sunburnt even appear bask in spot. Uv rays also damage the skin’s ability to retain moisture, leaving our skin dry, peeling and prone to wrinkles. In order to protect our skin, we need to protect ourselves from the sun.

There are two ways that sunscreen can help you avoid the sun’s harmful ultraviolet (UV) rays. Some do this by scattering light and reflecting it off the body. Another is absorbed before uv rays reach your skin.

So which is the best sunscreen? Obviously, you need a broad – or multispectral sunscreen with UVB and UVA protection. Ingredients with extensive protection include diphenyl ketone (hydroxymethyl diphenyl ketone), cinnamate (octylmethyl cinnamate and sinoxate), sulfoisophenone, salicylate, titanium dioxide (titanium white powder), zinc oxide, Parsol 1789, and ecammexoryl SX.

We need UVB protection with SPF 15 or higher. The SPF measures the effectiveness of a sunscreen against UVB rays. If you normally get a sunburn within 10 minutes, then SPF 15 multiplicates that by 15 times, which means you’ll be sunless for 150 minutes.For most people, SPF 15 is fine. But those with fair skin, a family history of skin cancer or greater sun sensitivity, such as lupus, should consider a sunscreen SPF 30 or higher.Remember, the higher the SPF, the smaller the increase: SPF 30 is not twice as effective as SPF 15, as you might think. While SPF 15 filters 93 percent of UVB rays, SPF 30 filters 97 percent, with only a slight increase.


Sensitive skin in infants and children can be easily irritated by chemicals found in adult sunscreens, so avoid sunscreen containing aminobenzoic acid (PABA) and diphenylketone (such as dioxanone, hydroxybenzoate, or shulinone). Children’s sunscreens use ingredients that are less likely to irritate the skin, such as titanium dioxide and zinc oxide. Unlike other chemicals, these protect the baby’s skin from being absorbed.For children 6 months or older, choose a sunscreen with an SPF of 15 or higher. The American academy of pediatrics recommends that infants under six months of age avoid the sun entirely.

People with skin allergies or skin conditions such as rosacea can also use sunscreen designed for children. Use titanium dioxide or zinc oxide instead of chemicals such as aminobenzoic acid (PABA), dioxybenzone, oxybenzone, or sholinone. If you have skin irritation or allergies, avoid using sunscreen containing alcohol, spices or preservatives.

If you’re exercising or swimming, you’ll need a waterproof and sweat-resistant sunscreen. But to understand what that means, the U.S. food and drug administration defines waterproof sunscreens as SPF levels that stay in water for 40 minutes. It’s very waterproof which means it’s effective after 80 minutes of swimming. These sunscreens aren’t absolutely waterproof, so if you’re swimming, you’ll need to reapply them regularly.

Some people think that wearing sunscreen will completely protect them from the sun. But that’s not the case. No sunscreen can do that. No matter how high the SPF, no matter how thick you put it on, sunscreen won’t protect you completely. This misconception can be dangerous: people who think they’re safe can be exposed to too much sun for too long and increase their risk of skin cancer and other problems.Even your clothes don’t fully protect you. The average cotton T-shirt has a poor SPF of 4.
So in addition to using sunscreen well, there are other precautions you should take:

1. Stay in as cool a place as possible.
2. Wear sunglasses.
Stay indoors when uv radiation levels are at their highest, usually wearing a wide-brimmed sunhat from 10 a.m. to 4 p.m.
4. Wear sun-protective clothing, preferably with UVP (uv protection level) on the label. Wear at least dark, tightly woven clothing that provides more protection.
Finally, remember that sunscreen is important. But there’s more to protecting yourself from uv damage than just using sunscreen.
