Actual texture is the way something feels when actually touched (smooth, rough, etc.).
Implied texture is the way an artist uses line, color, and other elements and principles to create the visual illusion that something may be smooth, rough, etc.
Louisa's skin sppears smooth and life-like. After color was applied to the canvas, a large soft-hair brush was used to lightly soften and blend. By carefully blending colors, Louisa seems to have life-like texture to her skin.
