Hydrolipidic Barrier
- non-acidic
- you need acidity & water to dissolve and let the corneocyte release off the surface of the epidermis
- TEWL
- Increases in post menopausal women
- lipid dry, flaky,
dehydrated, sensitivity &
fine lines
- Physical & chemical
- Physical - lipids, water & proteins
- Chemical - microflora, acid & PH
- Waterproof barrier
- Homeostasis
- 5.5
- Lipid
- sebum
- sebeacous gland
- holocrine gland
- concentrated on the face & scalp
- sebum
- influence of dihydrotestosterone
- androgen
- male hormone
- P acnes bacteria
- disease of the pilo sebeacous unit
- Triglyceride
- main nutritional source for P acnes bacteria
- Use PH balanced products
- professional homecare prep products
- Treatment protocols
- Chemical peels
- lamelar bodies
- stratum spinosum
- stratum granulosum
- secreted from the keratinocytes
- Odland bodies
- Golgi apparatus
- Cell
- Secretory organs
- Can become compromised by incorrect skin care products, caffeine, hormones
- Infection, ineffective desquamation & TEWL
- desquamation
- desmosomes
- epidermis
- NMF
- affected in old age
- water retaining mechanism
- mix of humectants
- all water soluble
- able to attract & retain water
- Glycoaminoglycans (GAG's)
- dermis
- hyaluronic acid
- holds up to 1,000 times its own weight
- balance & plumpness
- absorbs compression
- oestrogen increases production of GAG's
- menopause = reduced oestrogen = reduced GAG's
- too alkaline affects NMF
- stratum granulosum
- cell death (apoptosis)
- stratum corneum
- Filaggrin
- water retaining amino acid
- triglycerides, fatty acids & amino acids
- non greasy & hydrating
- aids hydration, desquamation, homeostasis, plasticity
- contributes & supports barrier function
- age = cells deficient in NMF
- due to health of the stratum corneum
- caused by extrinsic factors
- Skincare, PH, pollution, stress
- slows down with age
