What is caffeine?<\/h3>\n

Caffeine (INCI: Caffeine) is a naturally occurring alkaloid from the methylxanthine group. It is used in cosmetics for its stimulating, decongestant, and lipolytic properties, particularly as a caffeine microcirculation booster.<\/p>\n

Physicochemical data:<\/h3>\n

INCI: Caffeine<\/p>\n

Chemical name: 1,3,7-trimethylxanthine<\/p>\n

Molecular formula: C\u2088H\u2081\u2080N\u2084O\u2082<\/p>\n

– Molar mass: 194.19 g\/mol<\/p>\n

– CAS number: 58-08-2<\/p>\n

– Appearance: white, odorless crystalline powder<\/p>\n

– Solubility: moderately soluble in water, more soluble in warm water, highly soluble in organic solvents<\/p>\n

The relatively small molecular size promotes penetration through the skin \u2013 including through hair follicles.<\/p>\n

In which plants does caffeine occur naturally?<\/h3>\n

Caffeine is synthesized by plants as a natural protective substance. It occurs in, among others:<\/p>\n

– Coffea arabica (coffee),<\/p>\n

– Camellia sinensis (tea),<\/p>\n

– Paullinia cupana (guarana),<\/p>\n

– Ilex paraguariensis (mate),<\/p>\n

– Cola acuminata (cola nut),<\/p>\n

– Theobroma cacao (cocoa, in smaller quantities).<\/p>\n

Industrial extraction<\/h3>\n

Caffeine is extracted on an industrial scale in two ways:<\/p>\n

Extraction as a by-product of the decaffeination of coffee or tea through purification and crystallization.<\/p>\n

Chemical synthesis, often industrially via the Traube synthesis from urea and chloroacetic acid derivatives.<\/p>\n

High-purity, pharmaceutical-grade caffeine is used for cosmetic applications.<\/p>\n

Mechanisms of action in the skin: As a caffeine microcirculation booster, the active ingredient has several effects<\/h3>\n

1. Improvement of microcirculation: Caffeine stimulates local blood circulation and can thus support a more vital skin appearance.<\/p>\n

2. Inhibition of phosphodiesterase: Increases cAMP \u2192 activation of lipolytic processes (relevant for anti-cellulite products).<\/p>\n

3. Decongestant effect: Vasoconstrictive and draining \u2013 ideal for eye care.<\/p>\n

4. Stimulation of hair follicles: Increases metabolic activity in the hair roots.<\/p>\n

Studies as Caffeine microcirculation booster<\/strong><\/h3>\n

– Hair growth: University of Jena (Fischer et al., 2007). In vitro, caffeine showed a stimulating effect on human hair follicles and was able to partially compensate for testosterone-related growth inhibition.<\/p>\n

– Follicular penetration: Otberg et al., 2008. Topically applied caffeine can effectively penetrate the skin via hair follicles.<\/p>\n

– UV protection effects: Animal models showed photoprotective effects of topical caffeine (Lu et al., 2011).<\/p>\n

– Lipolysis: Various in vitro studies<\/p>\n

– Evidence of cAMP-mediated lipolysis in adipocytes.<\/p>\n

These data support its positioning as a functional caffeine microcirculation booster for skin and hair care.<\/p>\n

Advantages in cosmetic products:<\/h3>\n

– Promotes microcirculation<\/p>\n

– Supports hair growth concepts<\/p>\n

– Reduces swelling<\/p>\n

– Lipolytic effect<\/p>\n

– Antioxidant potential<\/p>\n

– Good skin compatibility<\/p>\n

– Versatile combinations<\/p>\n

Typical areas of application:<\/h3>\n

– Eye creams<\/p>\n

– Anti-cellulite products<\/p>\n

– Scalp serums<\/p>\n

– Firming products<\/p>\n

– After-sun care<\/p>\n

– Hair growth tonics<\/p>\n

As a modern caffeine microcirculation booster, caffeine is particularly suitable for performance-oriented dermocosmetic concepts.<\/p>\n

Formulation notes:<\/h3>\n

Application concentration 0.1\u20133%, can be easily combined with niacinamide, amino acids, peptides, and panthenol, stable in aqueous systems, pH-insensitive in the cosmetic sector.<\/p>\n
