Are Sunscreen and Sunblock the Same? Understanding the Key Differences

Living in the Emirates for a week proves that when considering what is the best sunscreen in UAE to buy, it is now more than just a beauty item and actually a necessity. From visiting Kite Beach on weekends to walking from your vehicle to your job in 45-degree weather, your skin is continually exposed to extreme UV radiation. While browsing through store shelves or shopping online, you may have noticed the terms “sunscreen” and “sunblock” being used interchangeably. Although both products exist to prevent you from getting burned, there is a significant difference in how they affect your skin.

To properly build an effective skincare routine in the Emirates to assist you with protecting your skin from the Arabian sun, the first thing you will need to understand is the difference between “sunscreen” and “sunblock.” If you are currently searching for a source to purchase your preferred product, before learning about how sunscreen works, we recommend looking at the complete collection of Sunkiss sunscreen products and sun protection items.

Sunscreen vs Sunblock: Which is Better?

Ultimately, how each of these products interacts with your skin is determined by both the product and the skin type of the individual. 

• Sunscreens use chemical filters to penetrate the skin and absorb UV rays which creates heat on the skin and enables the skin to release the heat through evaporation i.e., as a coolant effect (the air warms up as it rises).
• On the other hand, Sunblock has a physical component. It works by creating a barrier on the surface of your skin (like a mirror), allowing full deflection of the UV radiation for all people, regardless of their skin type.

Many people in the UAE can benefit from combining the strengths of both sunscreens and sunblocks by using them together but there is no one right answer. Those looking for light and fast-acting sunscreen options may find an excellent option in The Invisible Sun Shield CocoLime SPF 50. This product provides high levels of UVA/UVB protection without leaving behind the heavy "block" feeling of most products.

Chemical vs Physical Sunscreen: The Deep Dive

Chemical Sunscreen (The "Invisible" Choice)

Chemical-based sunscreens have been chosen by many individuals because they are easy to apply, and they provide good protection against UVA/UVB rays while being very thin. People tend to desire products that do not leave a chalky, white film which is why chemical sunscreens are often recommended for individuals who wear makeup or want to avoid having their sunscreen show through on deep skin tones. One downside to chemical products is that they require a minimum of 20 minutes for complete absorption before sun exposure. We have created an easy guide that breaks down the differences between chemical sunscreen sprays versus chemical lotions to assist you in making a decision that suits your quick needs in the morning.

Physical Sunscreen (The "Mineral" Shield)

Physical sunscreen products (also referred to as Mineral Sunscreens) typically consist of zinc oxide and Titanium Dioxide. They are recommended as a mineral sunscreen for sensitive skin, as these products do not penetrate through the skin; rather they simply cover and protect the skin. As chemical sunscreens do not penetrate the pores they are not as likely to produce breakouts and irritate your eyes when you perspire.

Why Mineral Protection Matters in the Middle East

When looking for sunscreen for hot climates UAE, minerals have a distinct advantage. Heat can sometimes cause chemical sunscreens to break down faster on the skin if they aren't reapplied. A mineral sunblock zinc oxide SPF 50 is incredibly stable and won't degrade as easily under the direct midday sun.

For those focused on keeping their skin youthful, the Age-Defying Daily Face Protection SPF 50 provides that essential SPF 50 for anti-aging protection. Since the sun contributes approximately 80% to visible skin aging, using a physical barrier can help prevent the development of fine lines and sun spots if used proactively.

The Secret to UAE Sun Care: The "Top-Up"

Due to climate conditions, you will sweat, therefore no matter how "water-proof" your sunscreen is, if you are active on a daily basis it will not last on your face all day. Reapplying sunscreen after sweating is the major reason people fail to protect themselves from the sun while at work.

To help prevent the build-up of sweat and to maintain the integrity of your makeup during the middle of the workday, you will want to use a facial spray throughout the day as your "top-up" product. The B5 Facial Spray is an excellent choice to keep your skin cool, calm and moisturized between lathering on more sunscreen lotion. A common question from consumers is whether or not spray sunscreen is safe to use. Yes, you should use a sufficient amount of product and reapply every two hours while spending time outdoors in the sun.

Making the Right Choice for Your Skin

What are some methods for helping you determine which sunscreen is best for you? Which criteria should be used in determining which sunscreen is appropriate for your use? Your decision about what sunscreen to use will be based upon both the type of outdoor activities you participate in and the various weather and environment conditions that you will experience when engaging in outdoor activities.

1. For the Gym/Beach: A water-resistant, physical sunblock is often more durable against sweat.
2. When working in an Office environment where you wear professional attire and makeup, then a Lightweight Chemical or Invisible (clear) Sunscreen works best.
3. Those with sensitive skin should stay with mineral formulations for their limited capacity to cause irritation or heat rash.

It doesn’t matter what kind of sunscreen you choose — the most important part is applying it consistently. The UAE sun doesn’t take breaks, and neither should your protection. With SunKiss, you can keep it cool, keep it shaded, and stay protected while still embracing that sun-kissed glow.
