Study Notes
Components of Cosmetic Products
- A cosmetic preparation consists of three components: an active ingredient, a base (or vehicle), and an additional substance.
- The active ingredient is the main component that produces the main effect, and it may be an antibiotic medication, a substance that inhibits aging, or a substance that lightens dark lesions on the skin.
- The base is the material that "carries" the active ingredient into the skin and ensures it remains chemically stable, penetrates the skin, and is released effectively.
- The three elemental bases are fatty bases, aqueous (water) solutions, and powders.
- Additional substances may include fragrances, dyes, and preservatives like benzoic acid, imidazolidinyl urea, and parabens.
Bases and Their Effects
- Fatty bases can increase the moisture level, soothe, or cool the skin.
- Aqueous solutions can have specific effects on the skin.
- Powders can also have specific effects on the skin.
Phases of Hair Growth
- The Catagen phase is a transitional phase that lasts 2-4 weeks, during which the hair stops growing.
- The Telogen phase lasts 3-6 months, during which the mechanism responsible for hair growth is inactive.
- The Exogen phase is when the hair is only loosely attached to the follicle and can be easily pulled out.
