The conversation covers topics such as the different types of melanin, the significance of skin of color, the impact of sunlight on the skin, and the long-term effects of sunscreen use. The episode concludes with recommendations for achieving healthy skin, including the use of sunscreen and skincare products with ingredients that manage discoloration.


  • Skin pigmentation is determined by the levels and types of melanin produced by melanocytes in the skin.
  • Individuals of all skin tones are susceptible to sun-induced skin responses, but the specific responses may vary.
  • Sunscreen with at least SPF 30 is recommended for all individuals, and it is important to find a sunscreen that works well with your skin tone.
  • A study conducted by L'Oreal Research and Innovation Division demonstrated that daily sunscreen use can protect the skin and improve overall skin quality in individuals with skin of color.
  • Consulting a dermatologist is important for personalized skincare advice, especially when considering exfoliation and addressing specific skin conditions.
