UVA


Sunlight has a major effect on the skin, causing premature skin aging, skin cancer, and many other skin changes.

Exposure to ultraviolet (UV) light-whether UVA or UVB-from sunlight accounts for 90% of the symptoms of premature skin aging.

Many skin changes that were commonly believed to be due to aging, such as easy bruising, are actually a result of prolonged exposure to UV radiation.

UVA was once thought to have a minor effect on skin damage, but now studies are showing that UVA is a major contributor to skin damage.

UVA is the major contributor to the photodegradation of tretinoin and isotretinoin (International Journal of Pharmaceutics, 352(1-2), 123-128).

Effects of UVA Exposure

Effects of UVA Exposure

The visible damaging effects of UVA only appear after years of exposure.

Early stages of incremental skin deterioration aren't visible to the naked untrained eye, so typically people will manage to secure copious impairment of their skin's functions (and therefore appearance) without meaningful intervention.

In recent years, the harmfulness of UVA has been more precisely demonstrated at cellular and molecular levels, using methods focused on the identification of biological targets of UVA radiation and the resulting cascade of impairment of cell functions and tissue denaturation.


Comparatively little exposure to UVA under conditions of anything less than near perfect protection sets marked aging en route:

  • wrinkling;
  • wilting;
  • laxity;
  • sagging;
  • shrivelled/shallow features;
  • sallow coloring;
  • patchy/mottled (hyper)pigmentation;
  • telangiectasia (broken capillaries);
  • dryness;
  • roughness;
  • and more (avoidable) aesthetic delights ...

Ideal protection is not offered by sunscreens alone.

Only certain sunscreens combined with certain antioxidants and retinoids found in formulas which reach the dermis constitute marked prevention of premature photoaging and allow for the best reversal of pre-existing skin aging currently possible.

UVA: The Trojan Horse of Premature Ageing of the Skin

UVA: The Trojan Horse of Premature Ageing of the Skin

Increasing evidence of the detrimental effects of ultraviolet A (UVA) impinging on the skin has emphasized the need for a new generation of skin care products that not only protect from UVB-induced sunburn, but rather provide effective protection throughout the UV range of sun radiation reaching the earth level.

The need is not restricted to products for sunbathers, whose primary concern is the conspicuous, acute effects of UVB and which do not take care of the hidden part of damage, the Trojan horse of premature ageing of the skin.

The need also applies to skin care products for daily use and exposure where UVA is a major factor whatever the season.

Aging solar exposure levels remain high throughout the year.

Presently the only solution for near perfect defense is to combine once daily use of topical antioxidants C, E and Ferulic Acid or another similar solution-stabilizing antioxidant with a "true" broad spectrum sunscreen such as Skinceuticals Daily Sun Defense SPF 20.

Anthocyanins, Lutein and Zeaxanthin are dietary constituents of the arsenal against premature skin, and general, aging.

Different sunscreens provide different kinds of sun protection and the periocular region requires different care.

Despite extensive education, most people still don't understand, choose to ignore or follow best practice anti-aging skin care recommendations only haphazardly.

This is disappointing, and suggests that the din of ineffective but aggressively marketed cosmetics generally overcomes the truths and concrete improvements dermatology represents while ensuring the perennial rise and fall of more or less identical misinformation.

Physician-endorsed skin care, where it is spurious, is a travesty of the medical profession, likely to degrade confidence and popularly expected standards of care.
