Enigmatic characteristics of the sun and necessity of utilizing SPF

About sun protection.

I consistently underscore the importance of year-round utilization of SPF. This is attributed to the persistent potency of UV-A and UV-B radiation across all seasons.

It is imperative to acknowledge that UV exposure can pose significant risks in the absence of dependable safeguards, such as products containing SPF.

UV RadiationIn addition, UV radiation directly affects photoaging and chromostaining. Both processes pertain to more profound alterations within the skin’s layers, thereby distinguishing themselves from each other. However, they manifest in a common outcome to a greater extent – skin thinning, sagging, the formation of both deep and fine wrinkles, senile angiomas, keratoses, pigmentation irregularities, and others.

Elastosis is yet another manifestation of ultraviolet influence – this occurs due to the fact that UV disrupts the structure of elastin fibers, reducing the density of the microfibrillar network in the dermis. Furthermore, it elevates the level of proteolytic enzymes, leading to the degradation of collagen and elastin fibers.

In the image, there is a well-known depiction of a 69-year-old male who spent 28 years behind the wheel of a truck. Throughout, the window exposed his face predominantly to sunlight, affecting solely the left side of his visage.This is a photograph of a woman who spent approximately 15 years working in an office near a window, through which sunlight consistently impacted only one side of her face.

Presently, we have two highly secure options for sun protection cosmetics:

Physical Filters (or Mineral):
Next-Generation Chemical Filters

How do they work?

Physical filters reflect UV radiation when it strikes them. There are only two physical filters: zinc oxide and titanium dioxide.

Pros:

They are highly safe (suitable for all, even children)
UV-A/UV-B protection
Requires reapplication every 2-3 hours
Ideal for problematic or irritated skin
Excellent choice for beach activities

Cons:

Can leave a white cast
Can complicate application of other cosmetics

Chemical filters absorb UV radiation and convert it into less harmful heat energy. Examples include Tinosorb M, Tinosorb S, Mexoryl XS, Uvinul A, Neo Heliopan AP.

Pros:

High safety level
Requires reapplication every 5-6 hours
Can be used with other cosmetics (under makeup)
Lighter texture compared to physical filters
Offers additional moisturizing effects

Cons:

Can occasionally cause chemical irritation
Might lead to excess shine for oily skin types

There are also older-generation chemical filters: • Oxybenzone (Avobenzone + Octocrylene) or ButylMethoxydibenzoylmethane • Benzophenone • Homosalate • 4-Aminobenzoic acid (PABA) • Benzophenone 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 • Octocrylene

If you find these names in the ingredient list, they indicate older chemical filters which should be avoided as they are harmful. They are already banned for use in many countries.

How to Choose the Number?

All sunlight that reaches your skin is 100%. Divide 100% by the SPF index, e.g., SPF 30. 100 / 30 = 3.3%. Only these 3.3% of sunlight will reach your skin, while the remaining 96.7% will be blocked.

• SPF 15 – Blocks 93% of UV rays • SPF 30 – Blocks 97% of UV rays • SPF 50 – Blocks 98% of UV rays

In terms of choosing the number, it depends on the season, location, and your skin type.

Additionally, consider your skin’s characteristics and the product’s consistency when making a choice:

• For dry skin, creams or lotions are preferable; • For oily and combination skin, gels, lotions, or fluids are better suited.

Despite all of this, you should not be afraid of the sun, as it is indeed essential and beneficial for us in various ways:

• Sunlight’s warmth and light consistently uplift our mood and contribute to a positive day. • It aids in the synthesis of vitamin D and its precursors. • Additionally, it assists in the treatment of certain medical conditions.

You simply need to be aware of all the risks and know how to effectively protect yourself from them!
