Definitions

  • the present invention relates to compositions and methods for providing skin care benefits by selectively supporting the growth of beneficial commensal microbial strains in the human cutaneous microbiome.
  • Human skin harbours many diverse microorganisms, which colonize the stratum comeum of the epidermis and skin appendages such as sweat glands and hair follicles.
  • the total of microorganisms in and on our skin is termed the cutaneous microbiota, and the skin microbiome is their collective genome.
  • Microbial colonization is differentially shaped by the physiological and topological variation of the skin, and varies systematically among different skin habitats, such as between dry, moist, and sebaceous skin.
  • the human axillae (underarms) are covered by squames, hair shafts and follicles, eccrine, apocrine and sebaceous glands.
  • the axillary area represents a distinct ecological niche characterized by warm, moist and nutritionally rich conditions. Salts, proteins, squalene, sterols, sterol esters, wax esters, a wide range of lipids and fatty acids are secreted, thus sustaining one of the highest densities of microorganisms on the body surface.
  • 3M3SH 3-methyl-3-sulfanylhexan-1-ol
  • S. epideimidis colonizes predominantly the axillae, head, and nares.
  • metabolic products of S. epidermidis including organic acids such as lactic acid, improve skin moisture retention, maintain a low acidic condition on the skin surface, and improve rough skin texture.
  • S. epidermidis is also considered to supplement the barrier function of the epidermis and inhibit the colonization of skin pathogens such as S. aureus through factors such as nutrient competition, production of antimicrobial peptides (AMPs), immunomodulatory properties (inhibition of inflammatory cytokine production) and enhanced expression of tight junction proteins.
  • AMPs antimicrobial peptides
  • C. aeries is another major skin commensal that prevents colonization and invasion of pathogens, via the hydrolysis of triglycerides in sebum and release of fatty acids that are antimicrobial and contribute to an acidic pH of the skin surface.
  • the main intervention strategy used for the treatment of armpit malodours is the topical application of deodorants and antiperspirants.
  • Deodorants reduce the bacterial counts in the axillae and add perfume to mask the malodour formation.
  • Antiperspirants additionally block the eccrine sweat glands to reduce the moisture production.
  • the present invention addresses this problem.
  • An objective of the present invention is to provide skin care benefits by selectively supporting the growth of beneficial commensal microbial strains in the human cutaneous microbiome.
  • the present invention provides a composition for providing skin care benefits by selectively supporting the growth of beneficial commensal microbial strains in the human cutaneous microbiome, the composition comprising at least one biotin binding compound and at least one precursor for biotin biosynthesis selected from pimelic acid, salts thereof or an anhydride thereof.
  • the invention also provides a method for providing skin care benefits by selectively supporting the growth of beneficial commensal microbial strains in the human cutaneous microbiome, the method comprising the simultaneous or sequential administration to the skin of at least one biotin binding compound and at least one precursor for biotin biosynthesis selected from pimelic acid, salts thereof or an anhydride thereof.
  • the invention also provides the use of pimelic acid, salts thereof or an anhydride thereof, optionally in combination with at least one biotin binding compound, for providing skin care benefits by selectively supporting the growth of beneficial commensal microbial strains in the human cutaneous microbiome.
  • skin is understood as the layers which comprise them, from the uppermost layer or stratum corneum to the lowermost layer or hypodermis, both inclusive. These layers are composed of different types of cells such as keratinocytes, fibroblasts, melanocytes, mastocytes, neurons and/or adipocytes, among others.
  • skin care means regulating and/or improving cosmetic qualities of the skin. These qualities are subject to regulation and/or improvement both in healthy subjects as well as those which present diseases or disorders of the skin (such as psoriasis, lichen planus, folliculitis or atopic dermatitis).
  • Examples of skin care benefits in the context of this invention include reducing and/or preventing cutaneous, especially axillary, malodour; providing a smoother, more even texture; improving the elasticity or resiliency of the skin; improving the firmness of the skin; reducing the oily, shiny, and/or dull appearance of skin; improving the hydration status or moisturization of the skin, improving the appearance of fine lines and/or wrinkles; improving skin exfoliation or desquamation; plumping the skin; improving skin barrier properties; improving skin tone; reducing the appearance of redness or skin blotches and improving the brightness, radiancy, or translucency of skin.
  • a preferred method according to this invention is a method for reducing and/or preventing axillary malodour by selectively supporting the growth of commensal S.epidermidis and/or C.acnes strains in the human axillary microbiome, the method comprising the simultaneous or sequential administration to axillary skin of at least one biotin binding compound and at least one precursor for biotin biosynthesis as described above.
  • compositions and methods of the invention are aimed at modulating natural interactions between beneficial commensal microbial strains in the human cutaneous microbiome (such as S. epidermidis and C. acnes) and other prominent members of the human cutaneous microbiome (such as S. hominis, S. haemolyticus and S. lugdunensis ).
  • beneficial commensal microbial strains in the human cutaneous microbiome such as S. epidermidis and C. acnes
  • other prominent members of the human cutaneous microbiome such as S. hominis, S. haemolyticus and S. lugdunensis .
  • composition of the invention comprises, inter alia, at least one biotin binding compound.
  • biotin binding compound denotes any compound which is capable of tightly but non-covalently binding to biotin (5-[(3aS,4S,6aR)-2-oxohexahydro-1 H-thieno[3,4-d]imidazol-4- yl]pentanoic acid).
  • biotin-binding compounds examples include biotin-binding proteins such as avidin-type molecules.
  • Avidin is a basic (pi c.10), homotetrameric glycoprotein (molecular weight 66-69 kDa) that contains terminal N-acetyl glucosamine and mannose residues. Each of the four subunits contains 128 amino acids and binds to biotin with high specificity and affinity (K d of about 10 15 M). Each subunit is composed of eight antiparallel b-strands that form a b-barrel, whose wide end binds to biotin. Avidin is originally derived from the eggs of birds, reptiles and amphibians.
  • avidin-type molecule encompasses native and recombinant forms of avidin as well as native and recombinant forms of avidin analogues such as streptavidin. Derived from Streptomyces avidinii, streptavidin is a c. 56 kDa non-glycosylated homotetrameric protein that binds to four biotins with a K d of about 10 15 M. Streptavidin has a tertiary/quatemary structure and amino acid arrangement similar to those of avidin and shows a moderate sequence homology level of c.30% sequence identity and 40% similarity with avidin.
  • Streptavidin is non-glycosylated and has a slightly acidic pi of about 5-6.
  • Neutravidin is another avidin analogue. It is the deglycosylated derivative of avidin and has a molecular weight of about 60 KDa. In the absence of the carbohydrate moieties, the pi of neutravidin is only slightly acidic (c.6.3).
  • Bradavidin II is an avidin analogue that may be isolated from Bradyrhizobium japonicum, a nitrogen-fixing bacterium found in the root nodules of the soybean plant. Bradavidin II shows a moderate amino acid similarity with avidin (38%) and streptavidin (32%) but exhibits the same biotin binding affinity as avidin.
  • Avidin analogues also include modified avidins prepared via covalent attachment to the available lysines of avidin.
  • modified avidins prepared via covalent attachment to the available lysines of avidin.
