There are few techniques to create permanent cosmetic lip
enhancement:

Lip Line Natural

Created in a similar colour to the natural lips.
Lip Line Defined

It's usually created in a contrasting colour to the natural lips and gives a lip line make-up look. It gives definition and fullness to the lips.
Lip Line and Blush

Will define the outline of the mouth with soft shading which gets lighter towards the centre of the lip giving an amazing, natural looking pout.
Full Lip Tint

Will give the lips a perfect finish creating an overall natural lip colour. This volumising lip tint defines the contour slightly and discretely outside the border to give an impression of fullness with a hint of colour applied to the centre of the lip for a natural looking tint. The full lip tint enhancement also has a remarkable anti-ageing effect on pale lips that have lost their colour and lip line sharpness due to the ageing process.
