Sunscreens: An Overview

Learn why not all sunscreens are created equal…

Sunscreens for Today’s Consumers

It is well-known that UV exposure involves free radicals and leads to various types of damage at the level of the skin. Indeed, in the skin, free radicals induced by UV radiation cause damage to DNA and proteins, leading to the premature aging of the skin cells. When exposed to UV radiation, the skin undergoes alterations resulting in inflammation, photoaging  and various skin disorders. Typical signs of photoaging include wrinkling,loss of elasticity, increased skin fragility and slower wound healing.

As such, sun protection is key. Before delving into the various types of sunscreens and their ingredients, four essential concepts should be emphasized.

1. A sunscreen product is meant to remain on the surface of the stratum corneum to ensure efficacy.

2. Numbers can be misleading. SPF 50 will only block one additional percentage point.

3. Repeated application also is a must.

4. Most consumers do not apply sunscreen at the concentration tested by the FDA, meaning emphasizing how to apply sun care is key. The correct amount of product to use is a teaspoon for the face and a shot glass for the body.

Sunscreen compounds can be classified into three main categories:

Physical blocks.

Titanium oxide, zinc oxide, iron oxide, mica and silica. The last three mentioned are not sunscreens, but soft-focus effect powders. When incorporated into a cream at such size, titanium and zinc oxides often leave a white deposit on the skin, which consumers dislike. These compounds, however, are well tolerated by most skin types because they do not penetrate the skin.

Physical filters.

The most common example of a physical (mineral) filter is titanium radiation. Due to their small size, they do not leave a white deposit on skin, an advantage appealing to consumers. However, some have reported this ingredient leaves a sensation of dryness on skin.

Chemical filters.

Chemical filters are characterized by the wavelength at the absorption maximum and by their absorption coefficient, which is a unit measure of Chemical filters have the advantage of being very elegant in cream chemical filters are known to cause contact dermatitis, irritative dermatitis and photosensitivity. The filters that most commonly cause such reactions include benzophenones (benzophenone-3 or oxybenzone), butyl methoxydibenzoylmethane, methoxycinnamate, methylbenzylidene-camphor and aminobenzoic acid.

Are you concerned about sun damage?

Over exposure to the sun can lead to skin cancer. Since sun damage accumulates over time, it’s never too late to start a sun protection regimen. Montaser helps repair and possibly even reverse these signs of skin aging, up to 90 percent of which are caused by the sun. The photo below is from one of our happy clients.
