Dr. Daniel Sugai, a board-certified dermatologist, discusses three common skincare concerns he frequently encounters in his clinic: "tech neck" (wrinkles and laxity in the neck), crepey skin on the legs and arms, and easy bruising on the extremities. He offers practical advice and over-the-counter solutions for each issue, emphasizing the importance of sun protection, retinoids, moisturizers, and lifestyle factors like diet and exercise.
