What you will learn

Core ideas before application

Does every dull appearance mean increased melanin?

No; texture, dryness and lighting can contribute. Dullness is a broad description that needs a more specific observation.

Why address active acne alongside its marks?

To reduce a source of new marks. Ongoing inflammation can create new marks even as old ones improve.

Find the stratum corneum at the top and cell renewal below. This is thick skin, such as a palm; its clear lucidum layer is absent from facial skin.

Which photo comparison is more informative?

Same lighting, distance and area. Consistent conditions reduce changes caused by photography itself.

Which describes a scar rather than a colour mark?

A lasting depression or raised surface. A structural change differs from colour and may need different management.
