Unideep complications

Awareness of this problem led to the rapid development of new TCA peel formulas between 1990 and 2000. One of the first solutions put forward was the New Peel combination of TCA and Mikuda complex. The soft Peel formulation used asiaticosides and ginsenoids, glycerol, urea (carbamide), sorbitan monolaurate and methyldibromo-glutaronitrile, among other ingredients. Easy TCA , Unideep and Only Touch Peel (OTP) provided another answer to the problem these stabilized solutions consist of a base solution to which a determined quantity of 50% m/m TCA is added. There are no complicated calculations to be performed, the directions for use state precisely what volume of 50% m/m TCA solution should be added to the base solution to make up the Easy TCA , Unideep and OTP solutions, which provide peels to the basal layer, the papillary dermis and the reticular dermis, respectively. 

Easy TCA is a stabilized, homogeneous and adjuvanted solution with a final TCA concentration of 15% m/m, combined with alpha hydroxy acids (AHAs), antioxidants, vitamins and saponins. Unideep is a TCA peel based on the same principles as Easy TCA and reaches the papillary dermis readily and evenly it has a TCA concentration of 23% m/m. The application protocols for these two peels allow all depths to be reached. There is no point using higher concentrations that could cause complications (see Chapter 37). 

Easy TCA and Unideep consist of peel solutions as weU as a post-peel cream whose ingredients help achieve better results and avoid complications. Only Touch consists of a solution alone, but has to be combined with Easy TCA or Unideep , and thus benefits from the application of the post-peel cream of these peels as weU. 

Unideep was designed to make pre-peel preparation as easy as possible, at the same time as maintaining rapid re-epithelialization and limiting the risks of post-peel complications. Unideep is a by-product of Easy TCA (ETCA) technology and is a medium-depth peel that reaches the papillary dermis. 

Unideep is a TCA peel to the papillary dermis. Adapted from Easy TCA technology, it consists of a peel solution and a post-peel mask. Thanks to the post-peel mask, the erythema following the peel does not last as long as the erythema after a peel with TCA-SAS to the same depth. The erythema following Unideep lasts around 5-8 days (Figure 37.12), and the only treatment that it requires is an application of antioxidant cream (e.g. Renutriv ACE Lipoic Complex ) and Vaseline (see Chapter 23). If there is persistent localized erythema, there might be a local complication, and treatment is necessary. Effective sun protection must be used.
