Growth Factors for Skin: Dr. Daniel Gould Featured in Marie Claire

Beverly Hills plastic surgeon Dr. Daniel Gould, MD, PhD was recently featured in Marie Claire discussing the science behind growth factors and their growing role in regenerative skincare.

Growth factors are naturally occurring signaling proteins involved in the skin’s repair and renewal processes. In the article, Dr. Gould explains how these proteins communicate with cells to support functions such as collagen production, cellular movement, tissue repair, and healing. When incorporated into topical skincare, growth factors are designed to support these same biological pathways.

Dr. Gould also discusses the different sources of growth factors used in skincare formulations. Human-derived growth factors are among the most studied and closely resemble those naturally produced by human skin, while recombinant growth factors are created in controlled laboratory environments to provide purified and consistent signaling proteins. He notes that the evidence supporting plant-derived growth factors is considerably more limited because plant signaling biology differs from that of human skin.

The article explores how growth factor products may support collagen production, skin texture, barrier recovery, and the appearance of fine lines and photodamage. These regenerative properties can also make growth factors particularly relevant alongside treatments that rely on the skin’s natural healing response, including microneedling and fractional laser resurfacing.

According to Dr. Gould, growth factors may be particularly useful for adults over 30 and patients with thin or compromised skin who are looking for ongoing collagen and skin-quality support. Because they can be incorporated alongside many established skincare ingredients, they may also serve as part of a broader approach to maintaining healthier, more resilient skin over time.

As regenerative science becomes increasingly integrated into aesthetic medicine and skincare, understanding the biology behind these products is essential. Rather than viewing growth factors as a quick solution, the article highlights their role as one component of a consistent, science-driven approach to supporting skin quality, repair, and long-term rejuvenation.
