Home-mixed facial oils and balms fail when makers skip preservatives, confuse anhydrous and water-based batches, or copy a recipe with no batch math. Directories sell “clean” formulas without the safety notes that keep a product from going rancid.

A members-only vault of beginner facial oil and balm formulas, batch calculation worksheets, and preservative safety notes for indie makers. Founding-member library in progress. No lab claims, supplier partnerships, or customer results. Teaching drafts only. Not a cosmetic chemist course, not GMP certification, and not permission to sell unregistered products.
