Introduction

• Speaker: Dr. Maniv Shah
• Key topics: Skin health, acne management, hair loss, tanning risks, genital warts, and more.

Skin Health and Tanning

• Worst thing for skin: Tanning
  • Causes skin cancer and accelerates aging
  • Tanning booths increase risk of skin cancer
  • UVB radiation damages DNA; UVA accelerates aging

Acne Management

• Popping Pimples: Not recommended
  • Leads to infections and scarring
  • Pimple rupture damages surrounding collagen
  • Use spot treatments instead

Hair Loss

• No cure for hair loss:
  • Hair cells have a programmed death cycle
  • Treatments can slow hair loss but not cure it

Genital Warts

• Caused by HPV (Human Papilloma Virus)
  • Can lead to cervical and penile cancer
  • Treatments include liquid nitrogen and topical treatments
  • HPV vaccines significantly reduce cervical cancer risk

Accutane (Isotretinoin)

• Effective for acne treatment:
  • Decreases oil production, skin cell stickiness, and inflammation
  • Has side effects that need monitoring

Stress and Skin Health

• Stress increases acne
  • Stress hormone affects sebaceous glands
  • Vicious cycle: stress → acne → more stress
  • Meditation and exercise recommended

Antiperspirants vs. Deodorants

• Deodorants generally safer
  • Antiperspirants block sweat; some concerns over aluminum
  • Deodorants do not occlude pores

Hormonal Acne

• Common in women in 20s and 30s
  • Typically affects jawline
  • Different treatments for hormonal acne

Aging and Wrinkles

• Caused by volume loss and movement
  • Protection with sunscreen is key
  • Retinols help build collagen

Sunburn and Skin Cancer

• Sunburn increases skin cancer risk
  • Single sunburn in childhood increases risk by 50%
  • Use sunscreen daily

SPF Recommendations

• SPF 30 or higher recommended
  • SPF 15 is not sufficient

Infections and Piercings

• Infection care:
  • Clean with soap, water, and use topical antibiotics
  • See a doctor if severe symptoms occur

Windburn vs. Sunburn

• Sunburn more dangerous
  • Windburn results from combined effects of wind, low humidity, and sun

Skin Detox and Breathing

• Skin doesn't breathe
  • Breaks from harsh products can help

Moisturizers and Sweat

• Moisturizers can trap sweat
  • They prevent water loss but may cause a sweaty feeling

Tattoo Removal

• Laser targets ink chromophores
  • Breaks ink into particles for body absorption

Asian Flush

• Genetic mutation in acetylaldehyde dehydrogenase
  • Causes flushing and increased cancer risk

Spotting Skin Cancer

• ABCDEs of melanoma:
  • Asymmetry, Border, Color, Diameter, Evolving
  • Ugly duckling sign is also a warning

  • Use sunscreen lip balm
