skincare routine by age: the science-backed protocol for your 20s, 30s, 40s and 50s

Most skincare routines are built by accumulation: a serum that went viral, a cream a friend swore by, whatever promised firmer skin that month. But what drives skin aging at 25 is not what drives it at 45, so a routine that never changes its priorities can spend years working on the wrong problem.

And your birthday is only part of the picture. Some people's skin is running a decade ahead of their age, perimenopause can change what skin needs years before the 40s arrive, and the routine you will actually stick with is usually shorter than the one you think you need. So before you add another product, it is worth knowing what changes in your skin from one decade to the next and what each stage should prioritize.

In this Biohacking Beauty Class, we walk through a skincare protocol for every decade, from protection in your 20s to correction in your 30s and recovery in your 40s, 50s, and beyond. We get into the research tying sun exposure to 80% of visible facial aging, why NAD+ declines in aging skin, what makes many exosome formulas questionable, how to tell if your skin is aging ahead of your age, and the red light specs that actually matter.
