Fitzpatrick Skin Classification

The Fitzpatrick skin classification is based on the skin’s unprotected response to the first 30 to 45 minutes of sun exposure after a winter season without sun exposure. The categories are as follows:

· Red or blonde hair

· Light colored eyes  (light blue, light green, grey)

· Freckles are common

Basic Types of Acne Lesions

Acne is a term we use to describe inflammatory lesions that are red, raised, and sometimes painful. Inflammatory lesions that have puss visible through the skin are referred to as pustule, while red, raised lesions that do not have any visible sign of puss are called papules.

“Acne-prone ” people have non-inflammatory acne or “comedones” which refers to lesions, like blackheads and whiteheads that are slightly raised but are not red in color. A blackhead is an open pore clogged with oil and debris, while a whitehead is an obstructed pore that is enclosed by the skin.



Eczema is a chronically relapsing skin disease associated with erythema, scaly and oozing plaques, and severe itching.  Signs and symptoms of eczema are associated with a compromised immune system and a defective skin barrier.



Facial Photoaging

Photoaging occurs overtime as we are exposed to sunlight and pollution. Characteristics of photoaged skin include darkened areas of pigmentation (brown spots and patches), wrinkles, rough-looking skin, and facial sagging.

Global facial wrinkles are defined as wrinkles in one or more areas including the forehead, glabella (between the eyes), crow’s feet (side of the eye), Under the eyes, nasolabial (between the nose and cheek area), around the lips, or marionette (extending downwards from the corners of the lips).

Lip Wrinkles

Crow’s Feet Wrinkles

Crow’s feet wrinkles are a wrinkle or wrinkles, that extend from the outer corner of the eye and extend beyond the orbital bone.

Undereye Wrinkles

Mottled Pigmentation

Mottled hyperpigmentation consists of darkened areas, or patches, of skin on the face, commonly found along the hairline, jawline, or cheeks.

Age Spots

Age spots are flat areas of discrete hyperpigmentation (darkening of the skin) that can be any shape but must have well-defined borders. They are often seen in areas of the skin that the greatest sun exposure, like the face (cheeks, forehead and the back of the hands).


Melasma is caused by hormonal changes and/or by sun damage and appears as symmetrical noticable brown patches on the cheeks, forehead, and jawline.

Post Inflammatory Hyperpigmentation

Post Inflammatory Hyperpigmentation (PIH) refers to the darkening of skin after the healing of inflammatory acne lesions. PIH usually has an indistinct border with a somewhat round shape and feels flat (even with the surrounding skin).

Facial Firmness and Sagging

Facial sagging is loss of firmness or sagging appearance of skin around the brow, cheek bones, and jawline.


Enlarged Pores

Individuals with enlarged pores have indentations that appear on the surface of the skin on the cheeks, close to the nose.

Under Eye Skin Conditions

Under Eye Bags and Puffiness

Under eye bags or “puffiness” is caused by fluid buildup under the eyes and loss of elastin, collagen, and muscle support.

Under Eye Dark Circles

Under eye dark circles are caused by poor circulation of blood under the eye that creates a purple-to-blue appearance or a brown black pigmentation under the eye close to the nose.

Hand Photodamage

Hand photodamage is due to sun exposure and environmental factors and can be seen by the emergence of age-spots (see below), thinning of the skin, and diffuse wrinkling that causes a surface appearance, similar to that of crepe paper.
