The Damage of the Sun on Skin
How does the sun actually damage skin?
The harmful effects of the sun stems from ultraviolet (UV)radiation exposure. When skin is exposed to the sun, it tries to protect itself by producing a chemical called melanin. This is a “natural” sunscreen that has a dark pigment that can reflect some of the dangerous ultraviolet light. Because the melanin pigment is dark, it makes your skin look dark, or tan.
Those with blond hair or light skin types have less melanin than darker individuals and thus burn more easily – and have a much higher risk of skin damage and cancer. Unfortunately, melanin only partially protects the skin from the energy of the sun, and a “deep” tan doesn’t really add much protection. UV rays that are not reflected but absorbed by the skin can damage the DNA within the skin cells.
Antioxidants and Skin Cancer
Free radicals are small molecules are produced within the skin as a result of UV damage. It is these free radicals that cause damage to a section of the DNA. Over many years, this damage causes the skin to age and lose collagen and to increase the chances of forming skin cancers. In order to combat against this damage, it is important that high dose antioxidants are used. These antioxidants have been clinically proven to prevent damage by neutralizing free radicals, which in turn results in limiting DNA damage and minimizing the effects of the sun on the skin itself.
The main difficulty with such therapy is the fact that specific antioxidants are usually formulated at low concentrations to be effective. Also
such compounds are unstable and denature quite quickly and are thus ineffective.Over the past 15 years Dr Langov in conjunction with compounding chemists has refined an antioxidant night cream. After many years of trial and error this cream has been formulated at the exact concentration to be effective. The formulation is stable, safe and with no known side effects.
Treatment of Hormonal Skin Pigmentation (Melasma)
Melasma (also known as the mask of pregnancy) is a tan or dark skin discoloration. Although it can affect anyone, melasma is particularly common in women, especially pregnant women and those who are taking oral or patch contraceptives or hormone replacement therapy (HRT) medications.
Melasma is thought to be the stimulation of pigment-producing cells by the female sex hormones estrogen and progesterone to produce more melanin pigments when the skin is exposed to the sun. Women with a light brown skin type who are living in sunny regions of Australia are particularly susceptible to developing this condition.Genetic predisposition is also a major factor in determining whether someone will develop melasma.
The incidence of melasma also increases in patients with thyroid disease. It is thought that the overproduction of melanocyte-stimulating hormone (MSH) brought on by stress can cause outbreaks of this condition. Other rare causes of melasma include allergy.
Differentiating the different types of Melasma is crucial in successfully treating Melasma.Using the wrong type of lasers or IPL therapy can result in skin necrosis, post inflammatory hyperpigmentation and hypertrophic scars. Over the past 15 years Dr Langov has developed a unique anti-melasma cream that contains active molecules that interfere with the deposition of pigmentation in the skin in order to slowly improve the complexion. This formulation does not bleach skin like other preparations, but lightens it, leaving the skin with a natural looking appearance. Side effects are usually minimal but may include skin inflammation and flakiness. Also this cream can not be used in pregnant woman or breast feeding mothers. To obtain optimal results an appropriate laser system may then used to clear additional pigmentation from the skin.
