Choosing a good sunblock is important to optimize skin protection from the dangers of the sun. Basically, the use of sunblock is intended to block ultraviolet rays from damaging the skin
Many conclude that choosing a good sunscreen or sunblock depends on how much SPF is in it, even though SPF content is only one of many other considerations. What is more advisable to do is to use sunblock regularly.
In general, the ingredients of sunscreen products are divided into chemical and physical categories based on their working properties. Chemical sunscreen ingredients work by converting ultraviolet (UV) rays into heat, so they do not harm the skin. On the other hand, physical sunscreen ingredients are able to reflect ultraviolet rays so as not to damage skin cells.
Wearing sunblock or sunscreen should be done regularly, especially by people who do a lot of outdoor activities and are exposed to a lot of sun exposure. Changing skin color to become darker is the body's natural effort to prevent cell damage that can lead to skin cancer.
Observing the Sunblock Content
It is generally known that long-term exposure to ultraviolet A (UVA) and ultraviolet B (UVB) rays can trigger skin cancer. Therefore, in choosing a good sunscreen or sunblock product, you must pay attention to its effectiveness in blocking UVA and UVB rays at the same time.In order for a sunblock product to be more effective, usually the following substances will be added to it:
EkamsuleSunblock with ekamsule material can block UVA and UVB rays, can be used for swimming, and has a low risk of irritating the skin.
Avobenzone In choosing a good sunblock, it should be stable when the sun hits it. If not, then its effectiveness in protecting the skin is questionable. One ingredient that belongs to this category is avobenzone. This material can block UVA rays, but is not effective against UVB rays. Although rare, this ingredient can cause dermatitis in some people.
BenzophenoneBenzophenone is often mixed with oxybenzone and dioxybenzone, which are common ingredients used in sunblocks. This material works by absorbing UVA and UVB rays and converting them.Besides being effective, benzophenone can also be used for swimming. Even so, sunblocks containing these ingredients can cause skin irritation in some people.
Titanium dioxide and zinc oxide
The ingredients that are widely used in sunblock products are titanium dioxide and zinc oxide. Both are materials that have long been used as ingredients for sunblock. Another advantage of titanium dioxide and zinc oxide is their ability to reflect UV rays that hit the skin.These two ingredients are proven to be safe and effective for the skin in preventing the negative effects of sunlight. However, because they are included in physical sunscreen ingredients, the use of these two substances tends to leave a white cast on the skin.
Other Things to Note
In addition to choosing the right sunblock support material, also pay attention to the following things:
Minimum SPF 30
Make sure to choose a sunblock with an SPF (sun protection factor) content of at least 30.The SPF number refers to the level of protection against UVB rays. SPF 15 can block 93 percent of UVB, SPF 30 blocks 97 percent of UVB, SPF 50 blocks 98 percent of UBV, and SPF 100 blocks 99 percent of UVB.
Water resistant doesn't mean waterproofThere is no truly waterproof', because after being exposed to water, the sunblock will be removed from the skin. The purpose of water resistance in sunblock packaging is that the product can be used for 40-80 minutes while swimming or sweating. However, after getting out of the pool or every two hours, sunblock must be re-applied.
Sunblock for sensitive skin
For owners of sensitive skin, choose a sunblock that contains zinc oxide and titanium dioxide. Both of these ingredients are included in physical sunscreen ingredients, so they don't absorb into the skin. In addition, choose sunblock k labeled hypoallergenic and without fragrance because it is safer for sensitive skin.
Sunblock texture according to skin type
If your skin is oily, choose a gel-textured sunblock because it is light and dries quickly. Sunblock gel is also suitable for use on hairy skin. For dry skin, choose a sunblock that contains moisturizer.Avoid spray sunblocks because they usually contain alcohol which makes the skin drier. Sunblock in the form of a cream is suitable for dry skin and can be used on facial skin. However, if your skin is prone to breakouts, avoid cream-textured sunblocks, because they will make the skin more oily, feel heavy, and cover the skin pores.
Friendly for children's he alth
The level of sensitivity of the skin of babies and children is different from that of adults. Therefore, do not apply sunscreen for adults to children, especially babies. For children, choose a sunblock made from natural, fragrance-free, paraben-free, alcohol-free, PABA-free, and phthalate-free sunscreens.Sunblock with titanium dioxide and zinc oxide can also be an option, because it is not easy to irritate children's skin. Just like on adult skin, these two ingredients can withstand ultraviolet rays and are not absorbed by the skin.
Remember that a good sunblock product should be able to protect the skin from UVA and UVB rays. The ability of sunblock, especially for the face, in blocking both types of UV rays, is usually written on the packaging label with the term broad spectrum. If you are going to do activities in a wet place or if the activity triggers sweating, choose products that are labeled waterproof. However, it is still recommended to reapply sunblock every two hours.
