Forensic facial reconstruction accurate reconstruction possible is largely limited. A second problem is the lack of a methodological standardization in approximating facial features. A single, official method for reconstructing the face has yet to be recognized. This also presents major setback in facial approximation because facial features like the eyes and nose and individuating characteristics like hairstyle - the features most likely to be recalled by witnesses - lack a standard way of being reconstructed. Recent research on computer-assisted methods, which take advantage of digital image processing, pattern recognition, promises to overcome current limitations in facial reconstruction and linkage. Reconstructions only reveal the
Facial tissue and its use. Facial tissue and paper handkerchiefs are made from the lowest basis weights tissue paper (14 18 g/m). The surface is often made smoother by light calendering. These paper types consist usually of 2–3 plies. Because of high quality requirements the base tissue is normally made entirely from pure chemical pulp, but might contain added selected recycled fiber. The tissue paper might be treated with softeners, lotions or added perfume to get the right properties or "feeling". The finished facial tissues or handkerchiefs are folded and put in pocket-size packages or a box dispenser. Facial tissue has been
