Is your skin and hair changing faster than you'd like after 40? You're not alone—and you're not imagining it. In this powerful episode of All About You, Dr. Shanna Wachs sits down with renowned regenerative medicine and anti-aging expert Dr. Amy Killen to unpack the real reasons why skin and hair health can suddenly shift during perimenopause and menopause.

We explore:

• How hormones like estrogen, progesterone, and testosterone affect aging skin and hair

• The science behind collagen loss, red light therapy, and regenerative treatments like PRP and stem cells

• Whether topical estrogen creams actually work for skin rejuvenation

• The truth about weight gain, belly fat, and muscle loss in midlife—and what really helps

• Myths and facts around GLP-1s, hair thinning, and hormone replacement therapy (HRT)

Whether you're in your 40s, 50s, or beyond, this is a must-listen for any woman looking to reclaim her radiance, confidence, and vitality. Don’t forget to hit subscribe and check the show notes for links to Dr. Killen’s work and resources!
