i don’t think about skin as “beauty”, i think about it as biology

For years, I’ve taught women that hormones, energy, metabolism, and aging are all part of the same conversation. Your skin is not separate from that system. It is one of the most hormonally responsive organs in your body.

When I look at skincare through that lens, I ask very different questions:

Does this support cellular energy?
Does it respect female biology?
Does it work with longevity pathways like NAD+ and spermidine?

That’s why Young Goose earned a place in my personal routine.

why hormones shape your skin after 40

I’m Dr. Stephanie Estima. My work focuses on female physiology, hormones, and metabolism, especially through perimenopause and menopause.

One of the biggest mistakes I see is treating women like small men with different hormones. That approach shows up in skincare all the time.

After 40, we don’t just lose collagen. We lose cellular communication, mitochondrial efficiency, and repair signaling. Your skin responds directly to estrogen, cortisol, insulin sensitivity, and inflammation.

That’s why surface-level hydration and generic anti-aging claims fall short. I look for skincare that supports the same longevity pathways I teach every day, products designed for female biology as it actually changes.

products I personally use and recommend

These are the Young Goose products I’ve integrated into my routine and why.

  • YOUTH DAILY & YOUTH RESET

    I think of these as daily and nightly support for skin energy and resilience. Just like we cycle nutrients and hormones, skin benefits from rhythm and timing. These formulas support hydration, barrier repair, and cellular renewal without overstimulation.

  • VAMPIRE EXOSOMES

    Exosomes are biological messengers. They tell cells how to repair, regenerate, and communicate more effectively. This serum delivers a clinically quantified dose of platelet-derived exosomes designed for daily use, without needles or downtime.

    If you understand PRP therapy, this is the topical, longevity-focused evolution of that science.

  • HYPERBARIC MASK

    Oxygen, circulation, and cellular recovery matter at every age. I use this when my skin feels stressed, inflamed, or depleted, especially during travel or high cortisol periods.

longevity over cosmetics

Young Goose approaches skin the way I approach hormones and longevity: from the inside out, at the cellular level.

Their formulations focus on:

  • NAD+ support for cellular energy
  • Spermidine pathways linked to autophagy and renewal
  • Exosomes as biological messengers for repair
  • Mitochondrial health and inflammation control
