Q

The longer, coarse hair found on the head, brows, lashes, genitals, arms, and legs.

A

Type of hair: Terminal

24
Q

The growth stage during which new hair is produced. The length of this phase determines the length of the hair. This stage is the most important for estheticians in effective hair removal, as removing hairs during this stage will be more effective for long-term hair reduction.

A

Hair Growth Cycle: Anagen Phase (1)

25
Q

The transition stage of hair growth. This is the shortest part of the hair growth cycle.

A

Hair Growth Cycle: Catagen Phase (2)

26
Q

The final, or resting, stage of hair growth. The hair is at its full size and length and is erect in the follicle, ready to shed.

A

Hair Growth Cycle: Telogen Phase (3)

27
Q

The process of removing hair at or near the level of the skin. Both shaving and chemical ____ are included in this category.

A

Depilation

28
Q

The process of removing hair from the bottom of the follicle by breaking contact between the bulb and the papilla. Tweezing, waxing, sugaring, and threading are all examples of this.

A

Epilation

29
Q

Treatment Objectives: Couperose

A
  • Calm and vaso-constrict
  • Hydrate
  • Normalize pH
  • Protect
  • Educate
30
Q

Treatment Objectives: Sensitive

A
  • Calm irritation
  • Insulate and protect
  • Restore barrier
  • Hydrate
  • Normalize pH
  • Educate
31
Q

Treatment Objectives: Alipidic

A
  • Insulate and protect
  • Restore barrier
  • Increase peripheral circulation and metabolism
  • Hydrate
  • Normalize pH
  • Educate
32
Q

The function of the ____ is to lubricate the skin and hair and help prevent TEWL.

A

hydrolipid film

33
Q

Suderiferous glands that open onto the skin’s surface and are acidic in nature. They are found all over the body and are responsible for the perspiration that cools the body and the acidity, or germicidal effect of the HLF.

A

Eccrine glands

34
Q

Suderiferous glands that open into the pilo-sebaceous follicle and are alkaline in nature. They develop during puberty in the axillary and groin regions and are responsible for odors emanating from the body during heavy perspiration.

A

Apocrine glands

35
Q

pH refers to ______.

A

potential hydrogen

36
Q

The hydrolipid film is also called the ____, and is made up of the secretions from the sebaceous and suderiferous glands, along with moisture from the environment.

A

acid mantle

37
Q

The skin’s ability to return to the normal value of approximately pH 5.

A

buffer capacity

38
Q

The pH in healthy skin ranges from ____.

A

4.5 - 5.5

39
Q

Result from the epidermal cells’ activities during keratinization (intercellular cement). These keratinized cells are water-resistant and are responsible for the barrier function of the skin.

A

hydrophobic fats

40
Q

Both sebum and perspiration contain fat and allow solubility with perspiration and environmental humidity. This natural emulsion acts as the ideal surface film, preventing moisture loss from the cutaneous tissue.

A

hydrophilic fats

41
Q

Fatty substances in the cutaneous layer (the epidermis) are the primary guards against liquid penetration of the epidermis. This is known as ______.

A

impermeability

42
Q

The skin’s ability to incorporate products into itself or even allow them to pass into the body’s interior is known as ______.

A

permeability

43
Q

Signifies the swelling of the horny layer cells. This results from the action of certain cosmetic products containing a high proportion of fluids.
Ex: steam, oil-in-water emulsions

A

Imbibition of the stratum corneum

44
Q

Represents the interaction between the cosmetic preparation and the corneocytes. Beauty products containing lipid and protein constituents surround the cellular membrane of the horny layer cells.
Ex: self-tanning lotions

A

Horny assimilation

45
Q

Penetration of a substance through the different strata of the skin and ultimately into the bloodstream and lymphatic system.
Ex: essential oils, hormone patches

A

Transcutaneous absorption

46
Q

_______, stimulated by the pituitary gland, is responsible for activating synthesis of melanin in the melanocytes of the epidermis.

A

Melanocyte Stimulating Hormone (MSH)

47
Q

When exposed to UV light, the skin produces ____ in the germinative, malpighian, and granular layers.

A

vitamin D

48
Q

The keratinization cycle takes approximately ____.

A

28 days

49
Q

Intercellular lipids, along with overlapping keratinized cells, protect against TEWL and outside invasion. This protection is known as the _______ of the skin.

A

barrier function

50
Q

The process of keratinization starts in the _____ layer and ends in the ____ layer.

A

germinative, horny

51
Q

Also known as ‘spider veins.’ A condition caused by dilated capillaries which appear as tiny spidery veins visible on the skin’s surface, usually over the nose and cheek area.

A

Telangiectasis

52
Q

A chronic state of capillary dilation, resulting in mild or more severe reddening of the skin. Generally seen on cheeks, jaws, or chin.

A

Hyperemia

53
Q

A medical condition involving several factors: capillary congestion, skin inflammation, chronic dilation of the capillaries, papule/pustule formation, and dehydration. Occurs mainly in the T-zone and cheek area, causing a butterfly effect on the face.

A

Rosacea

54
Q

This type of skin is inherited from birth. It is fine in texture and thin with blood vessels that lie very close to the skin’s surface. This skin is very delicate and reacts not only to external irritants, but also to internal stimulus (stress, illness, or PMS).

A

Sensitive skin

55
Q

Results from allergens. May be anywhere on the body. Reaction is usually delayed, more severe, and may take days to go away.

A

Allergic skin

56
Q

Factors leading to alipidic skin

A

Genetics, aging, medication, endocrine imbalance, liver dysfunction, makeup, improper cleansing, harsh products, drying environments.
