Stronger acids are used to correct deeper layers of the skin and the cells located there (pigment cells, connective tissue cells, elastic fibres, blood vessels). These stronger acids can only be applied by a trained doctor in a surgery. The medications used are only available to medical practitioners.
A detailed consultation and advice from the doctor carrying out the treatment is vital, as well as close examination of the skin by the doctor.
One very safe and effective procedure is trichloracetic acid peeling after Z. Obagi, known as a blue peel, which can be carried out well without local anaesthetic. In order to better assess the depth of penetration and monitor the effect, trichloracetic acid (TCA) is combined with a blue active substance (blue base). Based on the depth of the blue colouration of the skin, a designed blue peel can be carried out according to the desired effect. The greater the correction desired, the deeper the acid has to penetrate the skin.
The neutralisation of the acid in the deeper skin layers prevents too deep an effect, a factor which guarantees the high degree of safe usage of the blue peel.
In order to attain the optimum effect of a TCA peel, a six-week pre-treatment phase is recommended, carried out daily by the patient at home.
The peeling and regeneration of the skin begins two to three days after the TCA peel substance (blue peel) has been applied. At this stage the new skin is highly sensitive to mechanical stress and the effect of UV light. Complete healing is achieved after 10-14 days.
In contrast to laser treatment, any skin type and the skin of the entire body can be treated, including the backs of the hands, the décolleté and the neck.
