Zinc sunscreen

Types of zinc sunscreens

Zinc sunscreen is a popular sunscreen that protects against UVA and UVB rays. It contains zinc oxide, an ingredient that creates a physical barrier on the skin that reflects and blocks the sun's rays. There are different types of zinc sunscreens, which include the following:

• Lotions and creams

  These are lighter formulations that can be easily applied and absorbed into the skin. They are not as thick as traditional sunscreens and do not leave a white cast. This makes them suitable for everyday use. They are also water-resistant and provide long-lasting protection against the sun.

• Gels and gel powders

  These are non-comedogenic and do not clog the skin. They contain oil-absorbing ingredients that help to control shine and give a matte finish. This makes them suitable for people with acne-prone or oily skin.

• Sticks

  These are solid formulations that can be easily applied to the skin. They are small and convenient, making them perfect for on-the-go use. Zinc sunscreen sticks provide excellent coverage and are also water-resistant. They are suitable for people who engage in outdoor activities or sports.

• Powder

  These contain zinc oxide as an active ingredient and other components like silica, mica, and talc. They are also non-comedogenic and do not clog the pores. This makes them suitable for people with acne-prone skin.

• Gel formulas

  These zinc sunscreens are made with a high water content and a low percentage of oils and active ingredients. They have a light texture and are absorbed into the skin quickly. Zinc sunscreen gels leave no residue and keep the skin feeling fresh and hydrated. They are suitable for people with oily or combination skin.

How to choose zinc sunscreens

When picking a broad band sunscreen, there are a few things to think about before deciding. A few key factors are listed below:

• Type of formula

  There are many different kinds of sunscreen formulations. These include lotion, cream, gel, stick, powder, and more. Each type has its pros and cons. For example, lotions are thicker and may provide better coverage but can feel heavy on the skin. Gels are lighter but may not cover as well. Sticks are easy to apply but can be hard to blend in. Powders are great for touch-ups but need to be reapplied more often.

• SPF

  The SPF, or sun protection factor, measures how well a sunscreen protects against UVB rays, which cause sunburns. A higher SPF means more protection. However, no sunscreen blocks 100% of the rays. An SPF of 30 blocks about 97% of the rays, while 50 blocks 98%. So an SPF of 30 is usually high enough unless the person has very fair skin.

• Active ingredients

  The active ingredients in zinc oxide sunscreen determine how well it works. Look for ingredients like oxybenzone, avobenzone, octisalate, octocrylene, and homosalate, which provide broad-spectrum protection against UVA and UVB rays.

• Water resistance

  Water-resistant sunscreens maintain their protective levels for 40 or 80 minutes while the person sweats or swims. Regular formulas lose effectiveness when water hits them. Choose a water-resistant type if the person will be in the water a lot.

• Skin type and tone

  Consider if the person's skin is oily, dry, or somewhere in between. Some formulas work better on certain skin types. Also, think about skin tone. Sunscreens without chemicals are thicker and can leave a white cast on darker skin. A formula appropriate for skin type and tone will be used consistently.

• Sensitivities and allergies

  If the person has allergies or sensitivities, avoid formulas with a lot of added fragrances or chemicals that could irritate. Look for options that are gentle on the skin.

• Daily use and reapplication

  For sunscreen to work well, it needs to be reapplied throughout the day. Choose a formula the person can easily reapply, like a spray or powder, to make it more convenient. Sunscreens are an important part of protecting the skin from sun damage. By considering the factors above, buyers can select a sunscreen that best meets their needs and will help keep their skin safe from harmful UV rays.

How to use/install and product safety zinc sunscreens

Using and installing sunscreen is quite simple, as it requires no installation. Below is a step-by-step guide on how to use zinc oxide sunscreen.

• Cleanse the face

  Use a cleanser to remove dirt from the face. This will ensure that the sunscreen adheres properly to the skin. It will also prevent any blockage of pores that could lead to acne.

• Apply moisturizer

  For people with dry skin, use a water-based moisturizer to apply zinc sunscreen. This will help create a barrier that seals in moisture and prevent the skin from looking dry and scaly. Use a gentle cleanser to wash the face for people with oily or combination skin. So, they don't need to worry about their skin looking dry.

• Apply sunscreen

  Use a pea-sized amount of sunscreen for the face and a generous amount for the body. Use a gentle circular motion to apply the sunscreen and ensure it covers the whole face. Apply the sunscreen to the neck and ears, which are usually exposed to sunlight. Wait for about 20 to 30 minutes after application before stepping out. This will allow the sunscreen to bind to the skin for better protection.

• Reapply

  Reapply the sunscreen every two hours for better protection. For people who sweat a lot or are in a humid environment, they need to reapply the sunscreen more often.

Product Safety

Zinc sunscreen is generally safe for most people. It contains some natural ingredients that don't harm the skin. However, some people are allergic to certain ingredients in the sunscreen. They may experience some redness, itchiness, and inflammation. In such a case, discontinue use immediately. Look for sunscreen that has no fragrances or alcohol for people with super sensitive skin. Zinc oxide sunscreen is non-comedogenic. It won't clog the pores, reducing the chances of getting acne.
