Product Review: Garden of Wisdom Vitamin C 23% Serum & Ferulic Acid

Description (brand website):

Garden of Wisdom Vitamin C 23% + Ferulic Acid Serum provides high strength pure L-ascorbic acid to brighten and even out skin tone whilst Ferulic acid helps protect skin against free radical damage.

Vitamin C or specifically L-ascorbic acid, L-AA, is a powerful antioxidant with credible body of research supporting its skin benefits. Vitamin C has been shown to defend skin from free radical damage caused by UV exposure whilst enhancing the production of collagen. 

L-AA antioxidant powers also help prevent the oxidation of melanin, skin's natural pigment, resulting in a clearer, brighter and more even skin tone. Vitamin C serum also helps to inhibit the production of skin pigment, melanin, and is so used to prevent and treat hyperpigmentation. 

Ferulic acid is a powerful antioxidant found in the cell walls of plants. Ferulic acid not only protects vitamin C against oxidation but has been found to be destroying the superoxide and hydroxyl radicals thus helping to protect skin against ageing. Ferulic acid is particularly beneficial for protecting skin against sun damage.

Product Claims:

  • Contains 23% pure L-ascorbic acid, Vitamin C, in an airless pump to prevent oxidation
  • Non-greasy base, easily absorbed into skin
  • Brightens and freshens skin 
  • Particularly useful for preventing and treating hyperpigmentation
  • No added colours, fragrances and parabens
  • Cruelty-free 
  • A pH range of 3.1 - 3.4



As L-Ascorbic acid (the key active ingredient) is known to oxidize if exposed to air and light, the packaging is appropriately a white plastic airless pump bottle. However, it’s a bit temperamental, as after a few uses, the telltale orange stains appeared on the bottle and I’m not entirely sure how as I don’t recall having any spillages. Based on a quick google search, I discovered that others also had orange stained bottles due to this packaging and Garden of Wisdom have in fact changed the bottle a few times in a bid to deal with this.


How I use it:

I’m a Vitamin C in the PM type of girl so I use this product in my night time routine, after cleansing and toning as the first step of the treatment stage. I often follow it with hyaluronic acid or niacinamide depending on my skincare focus that night. I only use it 3-4 times a week as the other days I like to focus on exfoliation in the evenings.



  • As the product claims, the serum is easily absorbed into the skin and does not leave a greasy feeling. I imagine this is because it is water-based.
  • Upon application, I get an immediate brightening effect – my skin looks glowy. The panthenol in this formulation also helps to achieve the softening, moisturizing effect. I love the double dose of antioxidant with ferulic acid in the mix. As I get older, it becomes more and more important to protect my skin from photoaging.
  • This product did not cause any skin purging for me, likely because my skin has built a tolerance to vitamin C as I previously used a 20% vitamin C serum.
  • Over time (a month or more as I only used it 3-4 times a week), this product lightened my dark marks. My skin tends to scar pretty deeply, and my marks tend to be stubborn so I was pleased at its effectiveness.
  • It’s fragrance free, which I love.



  • Packaging is prone to leakages and staining. Other than that, I love this product and found it be effective at both brightening my skin and dealing with dark marks.
