Journal ArticleDOI
Nanoparticles--an efficient carrier for drug delivery into the hair follicles.
Juergen Lademann,Heike Richter,A. Teichmann,Nina Otberg,Ulrike Blume-Peytavi,Javiana Luengo,Javiana Luengo,Barbara Weiss,Ulrich F. Schaefer,Claus-Michael Lehr,Roger Wepf,Wolfram Sterry +11 more
TL;DR: It was found that the nanoparticles penetrate much deeper into the hair follicles than the dye in the non-particle form, if a massage had been applied and without massage, similar results were obtained for both formulations.
Journal ArticleDOI
Porcine ear skin: an in vitro model for human skin
Ute Jacobi,Marco Kaiser,Rani Toll,Susanne Mangelsdorf,Heike Audring,Nina Otberg,Wolfram Sterry,Juergen Lademann +7 more
TL;DR: The structure of porcine ear skin, including hair follicles, was studied qualitatively and quantitatively in comparison with human skin in studies of percutaneous penetration.
Journal ArticleDOI
Hair follicles - a long-term reservoir for drug delivery.
Juergen Lademann,Heike Richter,Ulrich F. Schaefer,Ulrike Blume-Peytavi,A. Teichmann,Nina Otberg,Wolfram Sterry +6 more
TL;DR: Interestingly, the storage reservoir capacity of the stratum corneum and the hair follicle infundibulum and canal are compared and it is shown that a 10 times longer storage within thehair follicles is demonstrated.
Journal ArticleDOI
The role of hair follicles in the percutaneous absorption of caffeine
Nina Otberg,Alexa Patzelt,Utkur Rasulev,Timo Hagemeister,Michael W. Linscheid,Ronald Sinkgraven,Wolfrarm Sterry,Jürgen Lademann +7 more
TL;DR: The findings demonstrate that hair follicles are considerable weak spots in the authors' protective sheath against certain hydrophilic drugs and may allow a fast delivery of topically applied substances.
Journal ArticleDOI
Investigation of Follicular Penetration of Topically Applied Substances
Juergen Lademann,Nina Otberg,Heike Richter,H.-J. Weigmann,U Lindemann,Hans Schaefer,Wolfram Sterry +6 more
TL;DR: A correlation between sebum production, hair growth activity and follicular penetration was observed and hair growth in the selected skin areas was determined.
