Doctor Explains: The Oil Combination That Reawakens Collagen in Mature Skin | Dr. William LII

Описание: As women age, changes in the skin are not merely cosmetic—they reflect deeper biological shifts happening within the dermal layer. After menopause, collagen production can decline rapidly, fibroblast cells become less responsive, and traditional remedies often stop delivering visible results.

In this 29-minute in-depth talk, Dr. William Li explains why castor oil alone is not enough to stimulate meaningful collagen repair in mature skin—and what’s missing at the cellular level.

You’ll learn:

Why fibroblast cells slow down after 50

How castor oil works as a carrier, not a collagen activator

The critical role of rosehip seed oil in collagen gene expression

How warmth, circulation, and gentle massage activate repair pathways

Why evening routines align with the body’s natural regeneration cycle

How stress, nutrition, hydration, and sleep influence skin aging

A science-aligned nightly protocol designed specifically for senior skin

This is not about chasing youth or using aggressive treatments. It’s about understanding how aging skin actually works—and supporting it intelligently, gently, and consistently.

If you’ve ever wondered why your skin feels soft but still lacks firmness, this video explains the biology behind that experience—and offers a practical, research-backed solution.
