Before applying serum, cleanse face and neck with philosophy’s purity made simple cleanser.


Birchbox Breakdown

It might not contain a genie, but this little bottle contains the next best thing (sorry, not Jake Gyllenhaal): a serum that both reverses and prevents the signs of aging. A signature blend of natural extracts and antioxidants reduce the appearance of fine lines, dark spots, and pores, resulting in a smoother, clearer, more youthful-looking complexion.

How to Use

Before first use, pour the entire vial of vitamin c8 activator into the serum and fasten pump to the bottle. Shake well for 20 seconds, until the serum turns light pink. Morning and night, apply a small amount of serum to clean, dry skin, avoiding contact with eyes. Follow with moisturizer, if needed. For the best results, use within three months of mixing.

Time in a bottle is absolutely amazing! It's the BEST serum I've EVER used! I love the consistency, texture, even the smell. Most of all I love the results! I'm in my mid-30s and started getting those little fine lines around my eyes. I've only used this a few weeks, but I can already tell a difference. I wear a mineral make-up and it usually "settles" down in the lines. Not-so with the Time in the bottle. My ONLY complaint, I was sticker shocked! Omg! I love it, but I will not be buying it again until I rack up some points! But as with most things, you get what you pay for. This is def true with the Philosophy brand!

I turned out pleased after finishing the bottle of this serum. However, like so many other treatments, I did not see any real difference after 2-3 months of use. Granted I am not wrinkled, etc. but I know vitamin C can do more than smooth fine lines and I never really saw any change in brightness, texture, etc. either. It was not too strong and did not irritate my skin. I liked how the potent C agent was in a separate bottle for mixing when i was ready to open the bottle. However, I guess it failed the final test, because I did not purchase it again after the bottle was gone. I am just trusting that some anti-aging took place while I was using it.

so far so good

I just started using this product and seems to be working pretty good for now. I'm excited to see the results in a few months. They said they can see the changes under a special light. Just need to find where they have one.

I received this as a sample from Philosophy and was blown away by how smooth it made my skin feel! This has made my list of future must have products. I gave the gel-like-serum about 3 minutes to soak into my skin before covering with my regular moisturizer and sunscreen. My face felt so soft and smooth, had to remind myself not to touch my face through out the day! I'll be stocking up my BirchBox points to purchuse this eventually, too expensive otherwise.

One of the better serums around

Now using my second bottle of this serum. I can see a difference in the texture and hydration of my skin. Not sure if it's helping the heavier wrinkles but makeup seems to go on better.

Expected better

I initially tried this product as a sample from Ulta while I was also using When Hope is not Enough serum (also from Philosophy). My skin was looking fabulous---dewy, fresh, and bright---and with all the great reviews on here I definitely thought it was from this product. My own fault for not trying products separately, but when I ran out of the serum and continued using this product, I did not get the same results. It's not a bad product, but I am just not noticing a significant difference like I did with the serum....and for the hefty price on this I definitely expected more. I have since purchased When Hope is not Enough (from Ulta---it is not on this site unfortunately!) and I LOVE that serum!
For the price of this, I don't think it is worth it.

Goes on well

This product goes on so smoothly. It feels sticky at first but quickly dries and pairs well with my moisturizer.

Worthless product

Don't waste your time or money on this product. I have used the entire bottle EXACTLY as directed (and wear sunscreen daily) and notice no difference in my skin . My two main reasons for trying this product were mild-medium dark spots and some rough patches. Neither concern was even slightly improved. Do not waste your time or money on this product

the best serum

One of the only things I use on my face, keeps me looking young and have recommended it to others. Also feels great, wonderful texture.

My favorite serum

So I may be a bit of a philosophy junkie. I've been using their products for almost 10 years. But this was a game-changer for me. I bought a full-sized product when it was released and didn't regret the expense for a minute. About a week after full time use I started to get complements on the evenness and youthfulness of my complexion.
I ran out about a month ago and haven't had a chance to order a new bottle yet (I've been supplementing with other products to get me by) and I can tell. My skin still looks good, but the time in a bottle really elevates my skin to a new level.
