The Moment Your Skin Changed. Forever.
When dermalogica meets skin, skin health is redefined. dermalogica is the number one choice of skin care professionals and consumers worldwide. Why? Because for over 25 years, we've been dedicated to delivering skin health results through education, innovation, and professional recommendation, not through sparkly packaging, promises of miracle cures, or overblown hype.
what causes oily skin?Sebum (oil) production is controlled by androgen hormones. Oils help lubricate skin, protecting it from environmental assaults (such as extreme weather conditions). Excess androgen hormones (due to puberty, monthly cycles or menopause) can trigger sebaceous (oil) glands to produce too much oil. This excess oil spills onto the skin’s surface, creating a slick, greasy appearance.
Causes of Hyperpigmentation: UV ExposureIn addition to the development of an overall tan, exposure to UV light may also stimulate hyperpigmentation in specific spots on the hands, face and neck. These dark spots are often referred to as age spots or liver spots (lentigines), usually become evident in our early forties, and become increasingly more evident as we age. By the time we reach 60 years old, 90% of all individuals will have sun-induced age spots, known as lentigines. These spots, more than anything else, give away a person’s age. Age spots are caused by skin’s continued exposure to the sun over many years, and unlike freckles, they do not fade in winter. (Freckles, also known as ephilides, are flat spots that are red or brown, typically appear during the summer months and fade in winter. They are most often found in individuals with fair skin and are generally a genetic trait.)
Causes of Hyperpigmentation: MelasmaHormonally induced pigmentation manifests itself in various forms, such as hyperpigmentation spots and melasma, better known as the mask of pregnancy. Melasma affects primarily women of child-bearing age. Some studies suggest that up to 75% of women may develop melasma during pregnancy and about 33% of women on birth control pills also complain of this problem. It is more prevalent in women with darker skin color and it is most commonly seen in areas that are exposed to sunlight.
Some scientists say UV exposure seems to be a requirement for melasma to develop, which may account for the fact that it is less noticeable in winter months when UV exposure is lower. The most common pattern for melisma is centrofacial: on the chin, upper lip, cheeks, nose, and forehead. To a lesser extent, melasma is seen on the cheeks and nose, or on the jawline.
The condition may persist up to 5 years after pregnancy or stopping of birth control pills. Unfortunately, once melasma manifests in skin, chances of having it again increase.
A true sensitive skin condition is caused by a genetic predisposition. Someone who is truly sensitive is born with this condition and tends to be prone to blushing, asthma and allergies. This skin is considered more delicate with less melanin or pigment, a thin epidermis and blood vessels close to the skin surface, hence the obvious appearance of redness. Sensitive skin is often the result of a defect in the skin’s protective outer layer – known as the epidermal lipid barrier layer – allowing irritants, microbes and allergens to penetrate the skin and cause adverse reactions. A disturbed epidermal lipid barrier is an important component in several inflammatory skin diseases such as rosacea, atopic dermatitis, psoriasis and eczema.
Rather than a result of genetics, sensitized skin is a reflection of your environment, lifestyle and physiology. Pollution, stress, hormonal fluctuations, smoking, alcohol, poor diet, medical procedures and even over-processed or over-exfoliated skin can all lead to sensitization. Cosmetic ingredients including alcohol, lanolin, fragrance and D&C colorants can also lead to sensitized skin. While those with fair skin (usually of Northern European ancestry) traditionally experience sensitive skin, sensitized skin can be triggered in any person regardless of racial background or skin color. Approximately 36% of the population in China has declared themselves to have sensitive skin, a condition that may in fact be attributed to the high level of pollution in both rural and urban parts of this region.
The common link behind irritation, flushing and stinging is inflammation. Paired with the loss of skin’s protective barrier, skin health is compromised and becomes highly reactive.
