Skin sum­mer love af­fair

Sun.Star Baguio - - OPINION -

YES dear read­ers, you are read­ing it right. Although for sure, a lot of eye­brows are raised be­cause con­ven­tional knowl­edge is that for the most part, sum­mer is not a friend, ac­tu­ally more of an enemy of the skin

As sci­en­tif­i­cally mea­sured by ge­niuses in physics –as­tro­physic­s­the dis­tance of the sun from Earth is about 150 mil­lion kilo­me­ters and from that far point of the uni­verse, the sun rays pass thru the five lay­ers of the at­mos­phere- ex­o­sphere, ther­mo­sphere, meso­sphere, strato­sphere and tro­po­sphere; where most of the harm­ful rays are de­flected by the ozone layer at the strato­sphere so that the so­lar rays hu­mans liv­ing in the sur­face of the earth are vis­i­ble light, in­frared rays, ul­tra­vi­o­let rays and a few x-rays.

The hu­man eye, with its re­cep­tors rods for night vi­sion and cones for bright day­light as well as color vi­sion can only rec­og­nize cer­tain col­ors in the spec­trum; red with the long­est wave­length up to vi­o­let with the short­est wave­length.

In­vis­i­ble to the eye are in­frared rays-longer than the red and ul­tra­vi­o­let rays, shorter than the vi­o­let. UVA or ul­tra­vi­o­let al­pha are the dry­ing, wrin­kle-form­ing and sag­ging-skin-form­ing rays, while the UVB or ul­tra vi­o­let beta are deeply pen­e­trat­ing so much so that, it may cause some de­range­ment in the deep­est layer of the epi­der­mis called stra­tum ger­mi­na­tivum , which may lead to a very deadly form of skin c can­cer called melanoma.

For­tu­nately, the highly de­struc­tive and harm­ful UVC or ul­tra vi­o­let gamma rays are bounced off by our ozone layer thus. Very lit­tle reaches the earth’s sur­face.

Der­ma­tol­o­gist and even your fam­ily physi­cian are all agreed on the use of sun­screens or sun­block to pro­tect your body, not just your skin from the harm­ful and age­ing ef­fects of so­lar rays. The SPF or sun pro­tec­tion fac­tor is a mea­sure on how safely/ how long a per­son can stay un­til the sun.

Ac­cord­ing to Dra. Pu­rita ChanNoble, one of fore­most board-cer­ti­fied skin spe­cial­ists in Baguio, SPF is the dose of UV rays re­quired to pro­duce min­i­mal ery­thema-red­ness­dose (MED) For ex­am­ple, an SPF of 30 means a per­son can stay 30 times longer un­der the sun be­fore MED ap­pears as com­pared if the skin is un­pro­tected. From this data, the higher the SPF, the bet­ter be­cause the per­son can stay longer un­der the sun? Well, yes and no. Yes, be­cause of the ex­tended pe­riod of stay un­der the sun; No be­cause even your own der­ma­tol­o­gist will tell you to stay out of the sun from 10am to 3 pm, when the scorch­ing heat of the sun is beat­ing on back of earth­lings. An­other very sen­si­ble cau­tion your colum­nist got from the ami­able Dra. Puree is that, sun­block must be re-ap­plied ev­ery now and then es­pe­cially for sun-wor­ship­pers.

An­other eye-opener is the re­al­ity that the sand, the wa­ter can re­flect ul­tra­vi­o­let rays even to some­one who’s rest­ing un­der the shade of a big beach um­brella, thus, sun­screens must also be ap­plied even you are just there to en­joy the sea breeze while read­ing your fa­vorite book. And for some skep­tics and cyn­ics, they too must give up their stub­born­ness and obey what skin spe­cial­ist says,; ap­ply sun­screen even on a seem­ingly gloomy cloudy day, be­cause above is still the sun.

Then for a com­plete sum­mer pack­age, how about a wide-brimmed hat, sun­glasses-brown and green dark tint are pre­ferred for reti­nal pro­tec­tion, loose light col­ored ap­parel and please don’t for­get your 8-10 glasses of wa­ter. Have fun, en­joy, take care.
