"The Brightener"

Give your skin a mega-dose of Vitamin C. Our 20% Vitamin C + E + Ferulic Acid serum brightens skin, builds collagen, and evens out tone. Enhanced with Vitamin E & Ferulic Acid, this serum is a great pick me up for dull, discolored, and stressed skin, while providing 24/7 protection against environmental pollutants. Recommended For: All skin types. 


  • Brightens dull complexions
  • Corrects hyperpigmentation and discoloration
  • Provides protection against environmental stressors

How It Works

Our Vitamin C + Ferulic Acid provides a 20% concentration of L-ascorbic acid, a highly effective skin anti-oxidant and collagen builder. This serum promotes healthy cell turnover to decrease the effects of hyperpigmentation and evens out skin tone. The lightweight, non-greasy formula absorbs quickly and transparently into the skin, while also being able to be added to any skincare routine. Use daily in the morning or evening to brighten, restore and help neutralize environmental stressors that can accelerate the signs of aging.  

Guaranteed fresh and effective until the expiration date printed on the box - approximately 6 months after purchasing. 


It is a common side effect due to the high concentration of L-ascorbic acid to notice mild irritation and redness, flaking of the skin, and/or even tiny red bumps. The ingredient, Vitamin E, may exacerbate an already oil-prone condition. Modify the use of serum by using fewer pumps until the skin has become acclimated to it to be sure this formulation is right for you.

Best vitamin c serum

I’ve been using this vitamin c serum for a few years now and I love it. It brightens up my skin and it feels very soothing. I can definitely tell the difference of how my skin looks and feels in those rare times when I have run out of it. Would highly recommend to anyone.


I'm an esthetician and work at a high end spa here in Salt Lake City , Utah
Since the Covid 19 pandemic I was looking for a skincare that would be more affordable for myself as well as my clients, that would give exceptional results. I'm grateful I came across Timeless.
I have very dry sensitive skin and I take very good care of it, so I can look my best. I'm 48 years old and I feel Timeless beauty products are excellent and everyone should give them a try!

My favorite vitamin C

this is the best vitamin C I have bought 3 times already, and this time was not the last. Thanks to Timeless

Love it!

I feel like my skin has definitely become brighter since using it. I love how it feels going onto my skin.

Promising Product

So far so good. I like this serum a lot. I use it every other night and I do think I see a brightening effect to my skin. Oils usually break me out but so far this one has not. It has a slightly oily texture but it sinks into the skin very fast. I will continue to use this product.
