The following scales will be used for grading these features: Roughness (degree of scaling and surface texture) - very smooth (1), mostly smooth (2), slightly rough (3), rough (4), very rough (5). Laxity (ability to spring back after pinching the skin) - very tight (1), somewhat tight (2), somewhat loose (3), loose (4), very loose (5). Mottled hyperpigmentation (a combination of lentigines and hyperpigmented and hypopigmented spots) - very even (1), mostly even with few blotches (2), blotchy (3), mostly blotchy (4), very blotchy (5).
