Sunscreen - A substance that helps protect the skin from the sun's harmful UV rays.
Both forms of UV light have been shown to increase the risk of skin cancer: With a longer wavelength, ultraviolet A (UVA) is linked to skin ageing. Skin burning is linked to ultraviolet B (UVB), which has a shorter wavelength.
Sunscreen for summer is one of our top requirements. There are hundreds of sunscreens available, and choosing the right one might be difficult. In this blog, we’ll be going through a 4-Step Process to choose the right sunscreen for YOU.
Step-1 : Choice of Spectrum
The first step is to determine what types of UV protection the sunscreen provides. This is also known as the activity spectrum. As a result, it's critical that you choose a sunscreen that protects you from both UVA and UVB rays, such sunscreens are called ‘Broad Spectrum’ Sunscreen which is the best sunscreen for summer
Step-2 : Sun Protecting Factor(SPF)
SPF is a measure of how much solar energy (UV radiation) is required to cause sunburn on protected skin (i.e., in the presence of sunscreen) compared to how much solar energy is required to cause sunburn on unprotected skin (i.e., in the absence of sunscreen). Unfortunately, SPF does not provide any information about UVA protection. It was created solely to assess UVB protection. The following is the measure of SPF,(EPA and Sunsmart)
SPF-15 : Blocks 93% UVB
SPF-30 : Blocks 97% UVB (Qurez Mattifying Mineral Sunscreen)
SPF-50 : Blocks 98% UVB (Organic Harvest Sunscreen)
The difference between sunscreen SPF 30 and SPF 50 is minimal. As a result, any broad-spectrum sunscreen with an SPF of at least 30 is a good choice. (Earth Rhythm SPF 50)
Keep in mind that the greater the SPF number, the thicker the sunscreen is likely to be. If you want to use sunscreen in your cosmetics, SPF 15 is a reasonable compromise between cosmetic results and sun protection.
Step-3 : Ingredients
To block UV rays, sunscreens contain a variety of chemicals. Physical sunscreens, also known as inorganic or mineral sunscreens(Amayra Naturals Ban The Tan- Mineral Sunscreen)
, and chemical sunscreens, sometimes known as organic sunscreens, are the two types of components. Both types of substances have advantages and disadvantages. Let's go over the key practical distinctions to assist you pick which ingredient group is best for your skin.
Zinc oxide or titanium dioxide are both used in physical sunscreens. Both of these chemicals are non-absorbable by the skin and are stable. Even nanoparticles of zinc and titanium cannot get through the epidermis' top layer, known as the stratum corneum. (TGA 2017).
Chemical sunscreens also contain a variety of additional chemicals. Octocrylene and Methoxydibenzoylmethane are two examples.
FDA Approved Ingredients in Chemical Sunscreens (FDA 2018)
- Aminobenzoic Acid
- Menthyl anthranilate
- Octyl methoxycinnamate
- Octyl salicylate
- Padimate O
- Phenylbenzimidazole sulfonic acid
- Trolamine salicylate
Sunscreens containing Titanium and Zinc are both broad spectrum, with Zinc blocking UVA somewhat better than Titanium. Chemical sunscreens can also be broad spectrum; to do so, they must contain a few distinct chemicals.
Sunscreen for acne prone skin, Sunscreen for dry skin, Sunscreen for oily skin. Generally, people with sensitive skin should use physical sunscreens(SkinCancer.org). People with acne, rosacea, or dermatitis such as eczema, for example. Also, because children's skin is undeveloped, children's sunscreen contains more physical components. If you don't have sensitive skin, you can use either type.
Step-4 : Ingredients
The final step is to choose the formulation you want to use. Sunscreens are available in the form of roll-ons, sprays, and creams. Because it's easier to create an even coating on your skin, roll ons and lotions generally provide the best sun protection of the three varieties. Because they produce an even coating on the skin, they provide superior protection than spray-on sunscreens(Cancer Council Australia at the World Congress of Melanoma 2017). It's simple to spray too little or unevenly using the spray-on sunscreens.
Other Factors to Consider
Water resistance is a useful characteristic to have if you're applying sunscreen before doing sports. Remember that even if your sunscreen is water resistant, you'll still need to reapply to get the UV protection you require. You can lose a lot of sunscreen while participating in sports. Some sunscreens are labelled as moisturising, which can be beneficial if you have dry skin.
When I know I'll be spending a long period outside, such as playing tennis, I apply a generous amount of a water-resistant chemical sunscreen. However, because I do experience acne on occasion, I pick a zinc sunscreen for daily usage to limit the risk of skin irritation.
