Did you mean Sebaceous Gland Activity?

Glossary Sebaceous Gland Activity

production of sebum by skin glands

Sebaceous gland activity refers to the function of sebaceous glands in the skin, which produce and secrete an oily substance called sebum. Sebum helps to lubricate and protect the skin and hair, but excessive activity can lead to oily skin and conditions like acne, while insufficient activity can result in dry skin.

research Oxidative Activity of the Type 2 Isozyme of 17β-Hydroxysteroid Dehydrogenase (17β-HSD) Predominates in Human Sebaceous Glands

45 citations , September 1998 in “Journal of Investigative Dermatology”

This study found that sebaceous glands predominantly exhibit oxidative activity of the type 2 17β-hydroxysteroid dehydrogenase isozyme, which is not inhibited by 13-cis retinoic acid.

research The Role of Sebaceous Gland Activity and Scalp Microfloral Metabolism in the Etiology of Seborrheic Dermatitis and Dandruff

241 citations , August 2005 in “Journal of Investigative Dermatology Symposium Proceedings”

This review discusses the roles of sebaceous gland activity, Malassezia yeast, and individual susceptibility in scalp flaking disorders, including dandruff and seborrheic dermatitis, but reports no new experiment results.

research Pharmacologic Modulation of Sebaceous Gland Activity: Mechanisms and Clinical Applications

30 citations , April 2007 in “Dermatologic Clinics”

This review discusses the mechanisms by which isotretinoin and hormonal therapy treat acne through their effects on sebaceous glands, reporting no new clinical results.

research Local stimulation of sebaceous gland activity by the topical administration of dehydroepiandrosterone

1 citations , January 1988

In this study, topical dehydroepiandrosterone (DHEA) doubled sebum production in women without systemic side effects, suggesting it may be a safe treatment for reduced sebum output related to menopause.

research Histopathological Findings and Proliferative Activity of Canine Sebaceous Gland Tumours with a Predominant Reserve Cell Population

5 citations , February 2015 in “Journal of Comparative Pathology”

This study suggests that high proliferative activity and peripheral invasion are key indicators of malignancy in canine sebaceous gland tumours. It also reports a higher incidence of circumanal gland and testicular tumours, indicating a possible androgen-related pathway in tumour development.

community Could a reversed SARM designed for the scalp serve as a replacement for oral Dut and Fin?

in Finasteride/Dutasteride 2 upvotes 1 year ago

The conversation discusses the potential of developing a selective oral SARM to target androgen activity in the scalp and skin, as an alternative to oral Dutasteride and Finasteride, which have systemic side effects. It also mentions Clascoterone and RU58841 as topical treatments for hair loss.

community Hot weather causing hair shedding?

3 upvotes 9 months ago

Hot weather can increase hair shedding, possibly due to dehydration and active sebaceous glands. Using shampoos with salicylic acid or zinc pyrithione may help; daily anti-inflammatory use is not recommended.

community Androgenetic alopecia is a skin disease: DHT-mediated skin disorders

63 upvotes 2 years ago

Dihydrotestosterone (DHT) impacts various skin conditions, including Androgenetic alopecia and seborrheic dermatitis, by causing overactivity in sebaceous glands. Topical medications Tacrolimus and Clobetasol can reduce these inflammatory conditions, and treatments like RU58841, Minoxidil, and Finasteride may also be beneficial.

community When you think about it blocking dht is not that big of a deal as it’s made out to be

in Research/Science 7 months ago

Reducing sebum can indirectly lower DHT levels, with treatments like accutane, tretinoin, and green tea extract acting as DHT blockers. Accutane can lower DHT levels by reducing 5α-reductase activity, but its impact on hair varies.

community "DHT Itch" and onset Seborrheic Dermatitis

in Research/Science 76 upvotes 3 years ago

The post and conversation discuss the link between DHT (a hormone), scalp itchiness, and hair loss. Some users share their experiences and treatments, including the use of fluconazole, corticosteroids, and ketoconazole shampoo, with one user suspecting minoxidil as a potential cause of their symptoms.
