Because homemade natural mixtures lack synthetic preservatives, any unused homemade baking soda cream should be discarded after a single use. Always prepare a fresh batch in small quantities to avoid bacterial contamination. Store your base ingredients—like carrier oils—in cool, dark places to keep them fresh.

No. While physical exfoliation can temporarily smooth surface texture, deep wrinkles require ingredients like retinoids, peptides, and daily sun protection to stimulate collagen production.
