What This Journal Is For
Most of what decides how your skin looks has nothing to do with a supplement. Sunscreen, sleep, how much you strip your barrier at the sink and what is on your plate all matter more, and most of them cost nothing.
These articles cover that ground first and cover supplement labels second, because reading a panel properly is a skill that protects you in a category where a great deal of nonsense is sold to women specifically. Gelagen is mentioned where it is relevant and left out where it is not.
Where To Start
- If you want one free thing that works: the sunscreen article, and it is not close.
- If your skin has started reacting to everything: the barrier article.
- If you are wondering why nothing has happened yet: the four week clock.
- If you are comparing supplements: how to read a panel.
- If you are wondering about collagen powders: what actually happens when you swallow collagen.
