Intro
Skin care product market has changed significantly and undergone rapid expansion during the past century, relatively few advances have been made in the understanding or classification of skin type. clinically observed, such as oiliness, resistance, or propensities toward pigmentation or wrinkling. The Baumann Skin Typing System (BSTS) is an innovative approach to classifying skin type that is based on four main skin parameters:
Four main skin parameters
1. Oily versus Dry
2. Sensitive versus Resistant
3. Pigmented versus Nonpigmented
4. Wrinkled versus Tight (Unwrinkled)
Oily (O) to Dry (D) Dry skin is characterized by either an impaired barrier, lack of natural moisturizing factor, or decreased sebum production.
- Oily skin
- Dry skin
- Normal skin
- Sensitive skin
- Resistant skin
- sebum production plays an important role in skin hydration by producing glycerol.
- oily skin is common complaint.
- oily skin. presents. as lipid- laden secretions resulting shiny appearance. over Tzone. leading to. sebaceous hyperplasia, large spen pores. factors predisposing to oily skin
Androgens. play a role in this. process because sebum secretion increases when puberty begins.
Acne breakouts tend to occur right before women menstrual cycle that recent study showed that menstruation is accompanied by dilatation of the pilosebaceous ducts.
Oily skin types are difficult to treat because there are no effective topical agents that significantly reduce sebum secretion. In addition, sunscreens, which are often soluble in oil, may increase skin greasiness Oily skin is best treated with a cleanser
- There are many external(hot water,detergents, friction to cloths, pollution, chemicals) and internal. factors that change the skin surface morphology & causes dry skin.
Dry skin arises from a loss of water from the outermost layer of the dermis characterized by dryness, Scaling & Dough texture.
Dry skin types need nonfoaming cleansers Toners should not be used in dry skin types. Moisturizers should be chosen based on their ability to decrease trans epidermal water loss and repair the skin’s permeability
- Types may change to dry skin types in low-humidity environments or in cold weather
- is characterized by inflammation and manifests as acne, rosacea, burning and stinging, or skin rashes.
Type 1 sensitive skin prone to developing open & closed comedones (acne type)
Type 2 sensitive skin characterised by facial flushing because of heat, spicy food, emotions(rosacea)
Type 3 sensitive skin characterised by burning, itching, stinging
- strongly protects the skin from allergens, other environmental irritants, and water loss.
