- Is the Timeless vitamin C serum worth it?
- At $12.42 at eBay as of November 5, 2026, it is one of the cheapest ways to get 20% vitamin C with vitamin E and ferulic acid. Buyers say it absorbs fast and moisturizes well, but some find it watery and less effective than pricier serums.
- How does it compare with SkinCeuticals C E Ferulic?
- Both use vitamin C, vitamin E and ferulic acid, but SkinCeuticals uses 15% L-ascorbic acid at a much higher price. Timeless uses 20% vitamin C and costs far less; some buyers say results are similar, others say not.
- Can I use it if I have sensitive skin?
- It is sold for all skin types, including sensitive skin, and is fragrance-free. A 20% vitamin C serum can still sting, so start with a small amount every other day and patch test first.
- When should I apply it?
- Use it once daily in the morning before moisturizer and sunscreen, or at night. Applying it to damp skin helps it spread and seal in moisture.
- How big is the bottle and how long does it last?
- It is a 1 oz (30 ml) dropper bottle. With one small application a day, most users get roughly one to two months from a bottle.
- Why is the price so low at eBay?
- The $12.42 eBay price as of November 5, 2026 is the lowest of 8 stores listing it new. Check that the listing is new in box and made in the US, since the serum oxidizes and older stock turns darker.
