- Is this serum worth it at $28?
- At $28 at Macy's as of November 6, 2026, it is a low-risk way to try a Philosophy hydrating serum. At full retail it is harder to justify against drugstore hyaluronic serums.
- How does it compare with the original Hope In A Jar moisturizer?
- This is a serum, not a cream. It adds hydration and a prebiotic, but you still need a moisturizer on top, especially in winter.
- Can I use it morning and night?
- Yes. Philosophy lists it for morning or evening routines, and it layers under sunscreen or night cream.
- Is it suitable for sensitive or acne-prone skin?
- It is paraben-free and marketed as non-comedogenic for all skin types, but it is not fragrance-free, so patch test if you react easily.
- What is in the 30 ml bottle?
- One 30 ml serum bottle. No applicator or travel size is included.
- When is the price lowest?
- Department store beauty events and sitewide sales are the usual windows for a drop below $28. Check the price history before buying at full price.
