Anthelios Sunscreens: How Mexoryl XL, SX and Other Sun Filters Work Together

Anthelios sunscreens with Mexoryl have an enviable reputation for their formulations, wearability and, of course, the effectiveness of the Mexoryl XL and SX sun filtering system. But have you ever wondered how the active ingredients in your sunscreen work together to protect your skin? To make the most well-informed decisions about sunscreen, it’s important to read labels and realize that not all sunscreens are created equal.

It’s important to first appreciate how the sun’s rays can cause skin damage. The sun is made up of shorter length UVB rays and longer length UVA rays. UVB rays are responsible for tanning and sunburns. UVA rays, on the other hand, penetrate deeper into the skin and contribute to wrinkles, premature aging, allergic reactions and some types of skin cancers. SPF (Sun Protection Factor) is a measurement of the amount of UVB protection that a sunscreen delivers. As of yet, there isn’t an official, international standard for measuring the UVA protection of a sunscreen. However, it’s taken that a ‘broad spectrum’ sunscreen will deliver adequate protection against both UVA and UVB rays. In our opinion, this is where Anthelios sunscreens excel!

Anthelios sunscreens stocked at PhaMix contain the ingredients Mexoryl SX and/or Mexoryl XL, which offer broad spectrum UVA and UVB protection. When combined with other effective sun filtering agents such as titanium dioxide, avobenzone, octocrylene or Tinosorb S, for example, Anthelios delivers excellent protection against UV rays. Many sunscreens on the market only deliver UVB protection, so while you may not get a sunburn, you aren’t protecting yourself against skin aging and skin cancers. In addition to their efficacy, Anthelios formulations are also highly photostable, meaning they don’t degrade when exposed to sunlight, thus preserving their protective properties. Studies have shown that Anthelios maintains the majority of its sun filtering capability even 24 hours after initial application.

As you wade through the myriad of sunscreens available on the market today, look for some of these key active ingredients to ensure the most comprehensive, broad spectrum protection for you and your family:

  • Titanium Dioxide: blocks UVB rays. It works by creating a physical barrier between the sun and your skin and is effective the moment you apply it. Titanium dioxide is inherently photostable, won’t break down upon UV exposure and is unlikely to cause skin irritation.
  • Zinc Oxide: Like titanium dioxide, this stable physical sun filter works by acting as a barrier between the skin and UV rays. Unlike titanium dioxide, it protects against both UVA and UVB rays.
  • Mexoryl SX: may also be listed as Terephthalylidene Dicamphor Sulfonic Acid. It blocks UVA rays measuring 290-400 nm, making it particularly effective in guarding against premature aging, wrinkles and other signs of aging.
  • Mexoryl XL: may also be listed as Drometrizole Trisiloxane; blocks UVA-II rays in the 320-340 nm range. When combined with Mexoryl SX, we think this sun filter provides the ultimate in UVA protection. Our most popular sunscreen is Anthelios XL SPF 60 Comfort Cream with 3% Mexoryl XL and 3% Mexory SX.
  • Avobenzone: blocks UVA-I rays. Ideally, avobenzone (butyl methoxydibenzoylmethane) should be stabilized with octocrylene. Anthelios XL SPF 50+ Lait Velouté features this important partnership along with titanium dioxide and Mexory SX, and with its 250ml / 8.45 oz size, the value is unbeatable.
  • Tinosorb S: blocks UVB as well as UVA rays measuring 280 nm to 400 nm. We’ve noticed that more customers are looking for sun protection that contains not only Mexoryl but also Tinosorb S, a chemical filter known for its photostability with a good safety profile. It isn’t associated with skin irritation and lacks hormone disruption effects associated with some older sun-filtering agents. Tinosorb S adds one more layer of protection against both UVA and UVB rays, an advantage that melanoma survivors are acutely aware of. You’ll find Tinosorb S in Anthelios Shaka Fluide SPF 50+ as well as Anthelios Ultra Cream SPF 50+.

The important thing is to select a photostable, broad spectrum sunscreen with a combination of active ingredients that protects your skin from both UVA and UVB rays that you’ll be happy wearing every day.
