Male Sexual Response: Erection & Ejaculation01:17

Male Sexual Response: Erection & Ejaculation

31.3K
Sexual stimulation can take various forms, such as physical touch and visual or auditory cues. When this happens, the parasympathetic reflex in the sacral portion of the spinal cord is activated. This reflex stimulates the release of nitric oxide (NO), which then dilates the arterioles in the penis, increasing blood flow to the erectile tissues - the corpora cavernosa and corpus spongiosum.
The blood filling the erectile tissues compresses the veins, which helps to prevent blood from leaving...

Renewal of Skin Epidermal Stem Cells01:12

Renewal of Skin Epidermal Stem Cells

2.4K
The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular...

Acne Infection01:27

Acne Infection

94
Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...

Accessory Glands of the Male Reproductive System01:16

Accessory Glands of the Male Reproductive System

4.9K
The accessory ducts involved in sperm maturation and transportation include the epididymides, vasa deferentia, ejaculatory ducts, and urethra. These ducts play a critical role in the maturation, storage, and transportation of sperm from the testes to the urethra, where it is then released during ejaculation.
The epididymis is a small, comma-shaped organ located at the back of each testicle. The epididymis can be divided into three main parts: the head, body, and tail. The head of the epididymis...

Penis01:29

Penis

50.8K
The penis serves a dual role in sexual reproduction and urination. It consists of three main regions: the glans penis, the body, and the root, each with distinct functions and unique anatomical features.
Anatomy of the Penis
The glans penis, or the head, is the terminal part of the penis and houses the external urethral orifice, the exit point for urine and semen. Covered by the prepuce, or foreskin, the glans is noted for its sensitivity and plays a key role in sexual pleasure. The body of the...

Clinical Applications of Epidermal Stem Cells01:19

Clinical Applications of Epidermal Stem Cells

2.4K
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

Summary

Men's skin care is a growing market, but product development lacks a clear strategy. This review proposes a rational approach to men's cosmeceuticals, considering male skin physiology and grooming habits for effective product design.

Area of Science:

  • Dermatology
  • Cosmeceutical Science
  • Men's Skincare Research

Background:

  • Increasing demand for topical anti-aging and cosmetic products specifically for men.
  • Lack of consensus on product properties required for effective male cosmeceuticals.
  • Current marketing of 'for men' products often lacks a scientific basis.

Purpose of the Study:

  • To develop a rational approach for men's cosmeceuticals.
  • To base recommendations on the anatomical and physiological characteristics of male skin.
  • To incorporate behavioral aspects relevant to men's grooming routines.

Main Methods:

  • Comprehensive literature review focusing on gender-specific skin singularities.
  • Analysis of male skin needs derived from physiological and anatomical differences.

  • Postulation of cosmeceutical strategies to address identified male skin requirements.

    • Main Results:

    • Cosmeceutical ingredients that reverse sun-induced skin damage are highly beneficial for men.
    • Tailoring cosmetic treatments to men's grooming habits, such as shaving, can improve product compliance.
    • Male skin possesses unique characteristics that necessitate distinct cosmeceutical considerations.

    Conclusions:

    • A science-based approach to men's cosmeceuticals is needed, considering skin physiology and behavior.
    • Targeted cosmeceutical ingredients and delivery methods (e.g., post-shave) can enhance efficacy.
    • Further research is warranted to refine the development and marketing of men's skincare products.
