PHOTO DAMAGE (SUN DAMAGED SKIN)

Photo ageing and photo damage (sun damaged skin) can also be described prematurely aged skin due to chronic exposure to sunlight (extrinsic ageing). Ultraviolet Radiation is the cause of ¾ of fine lines and wrinkles, and is either the causative or contributing factor for a majority of cosmetic skin conditions.

The effects of UVR on the skin include:

Anyone can suffer from premature ageing due to sun exposure. Those at higher risk include those who live in the tropics, at high altitude, work outdoors, engage in outdoor recreation activities and sports, have used sunbeds or solariums, have sunbathed for long periods or used tanning oils, and those who have fairer skin types (Fitzpatrick I and II). Photo ageing is preventable with use of SPF 50 daily and sun protection.

Although photo damage is the main cause of premature ageing of the skin. This can also occur from smoking cigarettes and other environmental factors such as pollution.

What is Ultraviolet Radiation (UVR)?

The sun emits various types of radiation that reach the earth’s surface, in the form of sunlight, infrared radiation which we feel as heat, and ultraviolet radiation that we cannot see. UVR is classified into 3 categories.

UVA – UVA is 100 times more prevalent than UVB. It can penetrate glass and clouds, and reaches the basal layer of the skin mutating DNA and can initiate the development of skin cancers. It is a longer wavelength and has lower energy than UVB but penetrates deeper.

UVB – Causes redness during and after sun exposure, mutates DNA and damages the superficial layers of the skin (epidermis). The intensity of UVB rays varies by the season. UVB is a shorter wavelength and a higher energy.

UVC  - Absorbed by atmospheric gases.

Chronic sun exposure can be as little 15 minutes of unprotected exposure per day and is enough to cause damage to DNA and cells responsible for producing collagen and elastin.

SYMPTOMS

Photo ageing can be classified according to the Glogau Photoageing Classification which is used worldwide.

Type I - Mild, no wrinkles

  • Mild pigment changes
  • Minimal wrinkles
  • No keratoses

Type II - Moderate, wrinkles in motion

  • Appearance of lines only when face moves
  • Early lentigines
  • Skin pores more prominent
  • Early changes in skin texture

Type III - Advanced, wrinkles at rest

  • Prominent pigmentation
  • Noticeable solar lentigines
  • Prominent small blood vessels
  • Wrinkles present when face at rest

Type IV - Severe, only wrinkles

  • Wrinkles at rest or moving
  • Yellow-gray skin color
  • Prior skin cancers
  • Actinic keratoses

TREATMENT

  1. SUN PROTECTION - this goes without saying. The daily use of SPF 50+ is needed to protect the skin from further UV damage and is the most powerful anti ageing treatment available. All clients at Youth Lab are strongly encouraged to be on a daily SPF (not in their makeup) and sun protection (and avoidance) is needed following any procedure performed in clinic.

  2. Removal of pre-cancerous and cancerous skin lesions by numerous means. Treatment options may include surgical excision, cryotherapy, photodynamic therapy, topical chemotherapy agent

  3. Cosmeceutical products - The use of active ingredients are essential to treat and prevent photoageing. Products such as AHAs work to exfoliate the damaged superficial layers of skin, moisturisers and emollients work to hydrate, retinol works to even out pigmentation and improve the appearance of fine lines and wrinkles, and antioxidants help to fight free radicals and protect the skin.

  4. Chemical peels - medical grade chemical peels can work to treat the visible signs of photo damage such as pigmentation, textural changes and fine lines/wrinkles. Various depths of peel can be used depending on the degree of photo damage and can effectively resurface the skin. A course of peels with regular maintenance treatments is recommended.

  5. Anti -wrinkle injections - anti wrinkle injections can assist in softening existing dynamic wrinkles which are often made worse by photo damage. They prevent muscle movement and cannot treat the wrinkles that have formed as a result of collagen and elastic loss

  6. Dermal fillers - fillers can be used to replace lost volume which is accelerated by sun exposure as well as to soften lines and folds which have formed more superficially. Softer fillers such as skin boosters can hydrate the skin and decrease the appearance of superficial wrinkles and collagen stimulaters ca help to improve skin quality and texture.

  7. BBL -  BBL can assist in reducing the appearance of photoageing by targeting stubborn pigmentation, visible redness and blood vessels. Forever Young BBL also assists in repairing DNA damage from sun exposure, repairing and rebuilding collagen and works to slow down the skin’s ageing process.

  8. Thread lifts - non-surgical face lifting with thread lifts can help to improve the appearance of sagging skin with a loss of elasticity. Thread lifts also work to stimulate collagen and elastin production and result in smoother, plumper and younger looking skin.

  9. Hydrafacial - Hydrafacial treatments not only have the benefit of cleansing, exfoliating and extracting but they can work to repair and rebuild sun damaged skin through the infusion of peptides and antioxidants. Antioxidants work to prevent further free radical damage and protect the skin from environmental damage (including the sun).

  10. Radiofrequency - skin tightening to improve appearance of skin laxity and poor skin tone

  11. Laser - vascular lasers can help to treat damaged blood vessels, redness, angiomas and capillaries, Lasers can also treat pigmentation and poor texture due to photo damage as well as remove keratoses and early skin cancers. Overall laser resurfacing can repair the skin and stimulate healthy collagen production.
