Approach to diagnoses

The physical examination of the skin and its appendages, as well as the mucous membranes, forms the cornerstone of an accurate diagnosis of cutaneous conditions. Most of these conditions present with cutaneous surface changes term "lesions," which have more or less distinct characteristics. Often proper examination will lead the physician to obtain appropriate historical information and/or laboratory tests that are able to confirm the diagnosis. Upon examination, the important clinical observations are the (1) morphology, (2) configuration, and (3) distribution of the lesion(s). With regard to morphology, the initial lesion that characterizes a condition is known as the "primary lesion," and identification of such a lesions is the most important aspect of the cutaneous examination. Over time, these primary lesions may continue to develop or be modified by regression or trauma, producing "secondary lesions."However, with that being stated, the lack of standardization of basic dermatologic terminology has been one of the principal barriers to successful communication among physicians in describing cutaneous findings. Nevertheless, there are some commonly accepted terms used to describe the macroscopic morphology, configuration, and distribution of skin lesions, which are listed below.

Makeup types

• Lipstick, lip gloss, lip liner, lip plumper, lip balm, lip conditioner, lip primer, and lip boosters.
• Foundation, used to smooth out the face and cover spots or uneven skin coloration. Usually a liquid, cream, or powder. Foundation primer can be applied before to get a smoother finish.
• Powder, used to set the foundation, giving a matte finish, and also to conceal small flaws or blemishes.
• Rouge, blush or blusher, cheek coloring used to bring out the color in the cheeks and make the cheekbones appear more defined. This comes in powder, cream, and liquid forms.
• Bronzer, used to give skin a bit of color by adding a golden or bronze glow.
• Mascara is used to darken, lengthen, and thicken the eyelashes. It is available in natural colors such as brown and black, but also comes in bolder colors such as blue, pink, or purple. There are many different formulas, including waterproof for those prone to allergies or sudden tears. Often used after an eyelash curler and mascara primer.
• Eyelid glue, eye liner, eye shadow, eye shimmer, and glitter eye pencils as well as different color pencils used to color and emphasize the eyelids (larger eyes give a more youthful appearance).
• Eyebrow pencils, creams, waxes, gels and powders are used to color and define the brows.

Also included in the general category of cosmetics are skin care products. These include creams and lotions to moisturize the face and body, sunscreens to protect the skin from damaging UV radiation, and treatment products to repair or hide skin imperfections (acne, wrinkles, dark circles under eyes, etc.). Cosmetics can also be described by the form of the product, as well as the area for application. Cosmetics can be liquid or cream emulsions; powders, both pressed and loose; dispersions; and anhydrous creams or sticks.

Lip stain is a cosmetic product that contains either water or a gel base. To help the product stay on the lips, many stains may contain alcohol. These lip coloring products are available in a variety of formulas, colors, and application types. The idea behind lip stains is to temporarily saturate the lips with color with a dye, rather than applying a colored wax to the lips to color them. A lip stain is usually designed to be waterproof so that the color will be long lasting, and once the stain dries, it should not smear, stain, wear unevenly, or transfer to the teeth. A lip stain may come in a bottle with an applicator which is used to brush the stain onto the lips, and it can also come in a small jar, with users applying the stain with a finger or a cosmetic brush.

Make-up remover is the product used to remove the make-up products applied on the skin. It is used for cleaning the skin for other procedure, like applying any type of lotion at evening before the person go to sleep.

Skin flora

The human skin is a rich environment for microbes.Around 1000 species of bacteria from 19 bacterial phyla have been found. Most come from only four phyla: Actinobacteria (51.8%), Firmicutes (24.4%), Proteobacteria (16.5%), and Bacteroidetes (6.3%). Propionibacteria and Staphylococci species were the main species in sebaceous areas. There are three main ecological areas: moist, dry and sebaceous. In moist places on the body Corynebacteria together with Staphylococci dominate. In dry areas, there is a mixture of species but dominated by b-Proteobacteria and Flavobacteriales. Ecologically, sebaceous areas had greater species richness than moist and dry one. The areas with least similarity between people in species were the spaces between fingers, the spaces between toes, axillae, and umbilical cord stump. Most similarly were beside the nostril, nares (inside the nostril), and on the back.
