How long do homemade skincare products last?
Short answer
From the book: cleanser, creams and toner 9 months; peptide serum and eye gel 6 months; facial oil 9–12 months; cleansing oil and shower gel 12 months; butters, scrubs and bath salts 6 months unopened, 3 months opened.
Explanation
These shelf lives assume the book's full protocol: sterilized tools and containers, the named preservative systems in water-based products, and antioxidants in oil-based ones. Airtight, suitable packaging matters too: airless pumps for gels, dark glass for oils.
What to do
- Label every product with its date and batch.
