Glossary Skin Barrier Formation

process by which skin's outer layer develops protective functions

Skin barrier formation refers to the process by which the outermost layer of the skin, known as the stratum corneum, develops to protect the body from environmental threats like pathogens, chemicals, and physical injuries. This barrier is composed of tightly packed dead skin cells and lipids, which work together to prevent water loss and maintain hydration, ensuring the skin remains healthy and functional.

research Targeted Skin Overexpression of the Mineralocorticoid Receptor in Mice Causes Epidermal Atrophy, Premature Skin Barrier Formation, Eye Abnormalities, and Alopecia

67 citations , August 2007 in “American Journal of Pathology”

This study found that overexpression of the mineralocorticoid receptor in a mouse model led to premature epidermal barrier development, keratinocyte apoptosis, and postnatal alopecia, indicating new roles for MR signaling in skin physiology.

research 874 Chromatin architectural protein CTCF controls epidermal barrier formation, hair follicle fate maintenance and suppresses inflammatory responses in the skin epithelium

April 2017 in “Journal of Investigative Dermatology”

In this study, CTCF was found to play essential roles in epidermal differentiation and skin barrier formation, simultaneously acting as a suppressor of epithelial inflammatory responses in mouse skin.

research 1397 LSD1 is critical for epidermal development and skin barrier formation

April 2023 in “Journal of Investigative Dermatology”

This study found that LSD1 is crucial for embryonic skin barrier formation in mice, revealing its significant role in epidermal development and suggesting its potential as a target in skin diseases with barrier defects.

research 177 The Striatin-Interacting Phosphatase And Kinases complex is important for skin epidermal differentiation and barrier formation

November 2022 in “The journal of investigative dermatology/Journal of investigative dermatology”

This study found that STRIP1 and the STRIPAK complex play a key role in regulating F-actin and cell-cell junctions, which are essential for maintaining the epidermal barrier in mouse skin.

community Topical Finasteride that doesn’t go systematic is the cure

3 upvotes 1 year ago

Topical finasteride that doesn't penetrate the skin could potentially treat hair loss without side effects. Current challenges include finding a formulation that remains on the scalp without increasing blood levels.

community Are we underestimating systemic absorption with homemade/generic Topical Fin? (HPCH vs. PG/Ethanol formulations)

5 upvotes 7 months ago

Topical finasteride may have higher systemic absorption and lower efficacy when using a Propylene Glycol/Ethanol formulation compared to the hydroxypropyl chitosan (HPCH) formulation. The safety profile of topical finasteride relies heavily on the HPCH formulation, and using standard solutions might lead to different pharmacokinetics.

community Does finasteride/dutasteride reverse aging?

in Chat 45 upvotes 1 year ago

Finasteride and dutasteride can improve skin texture and reduce acne by lowering DHT but do not reverse aging. They may enhance skin and hair health for some, but can also cause side effects like dry skin and sexual dysfunction.

community Minoxidil actually reduces wrinkles

in Research/Science 209 upvotes 1 year ago

Minoxidil may improve or worsen skin quality, with topical forms causing dryness and wrinkles, possibly due to alcohol content, while oral forms have fewer side effects. Some users consider using tretinoin to mitigate negative effects.

community New & Improved Hair Growth Stack for Maximum Results

5 upvotes 1 year ago

A user shared a hair growth stack using minoxidil sulfate, valproic acid, bimatoprost, blue copper peptide, and other ingredients, emphasizing a gel-based formula for better skin tolerance. Another user suggested adding a 5-alpha-reductase inhibitor like finasteride or dutasteride for more effective long-term results.
