Garden of Wisdom


Suitable for Vegetarians


C-Deep Vitamin C Serum contains Tetrahexyldecyl Ascorbate, a highly stable, fast absorbing vitamin C derivative which provides antioxidant protection against oxidative damage from UV and pollutants. Tetrahexyldecyl Ascorbate serum penetrates deeper than comparable Vitamin C serums to reduce the appearance of fine lines and wrinkles, as well as firm, even-out the skin tone and brighten your complexion overall. Discover more in Shabir’s article: ‘Is Tetrahexyldecyl Ascorbate The best Vitamin C Serum?’ here.

This Vitamin C face serum is super-lightweight, non-irritating and easily absorbed, is 100% stable, meaning it doesn't breakdown over time like other Vitamin C creams and serums. 

Just above the deepest layer of our skin lies a rich oil barrier. Traditional L-Ascorbic Acid vitamin C serums are water-soluble and therefore unable to penetrate this layer. Garden of Wisdom's C-Deep Vitamin C Serum contains Tetrahexyldecyl Ascorbate, a form of Vitamin C that has been modified to be soluble in oil or lipids and enters the skin faster and deeper than any other form of Vitamin C.

With its unique formulation, C-Deep serum effectively and efficiently boosts and stimulates the skin's collagen production - an essential protein that gives the skin its youthful firmness and elasticity. In addition, Tetrahexyldecyl Ascorbate stimulates the skin's Hyaluronic Acid production, helping to hydrate and plump skin cells and reduce the appearance of fine lines and wrinkles. The result is a noticeably more youthful complexion.

In addition, C-Deep Vitamin C contains thiotaine, the bio-identical lab form of L-ergothioneine, an amino acid found in mushrooms with an impressive antioxidant capacity helping to protect the natural antioxidants in skin from degrading. L-ergothioneine also inhibits and enzyme that stimulates melanin production and so also plays a role in fading skin discolourations. 

C Deep Vitamin C Serum benefits:

  • Reduces the impact of pollution and sun exposure.
  • Balances uneven tone.
  • Supports collagen manufacture and protects collagen to prevent ageing skin.
  • Helps Improves skin’s plumpness and elasticity.
  • Increases hydration levels.

Garden of Wisdom's C-Deep Vitamin C Serum is stable, safe, effective and suitable for all skin types including sensitive skin. Like all Garden of Wisdom serums, it is non-toxic and free from Alcohol and Silicones. Serum bottles are made of PET and are 100% recyclable.

How to use: Apply one to two pumps of vitamin c oil for the face and neck, morning and evening after cleansing. Leave it to absorb before applying other oil-based serums or moisturisers such as the age-defying Fulvic Face Cream. If using water-based serums, then apply C-Deep Vitamin C Serum after their use. If using in the day follow with an SPF. Build your complete Garden Of Wisdom skincare regimen here.

At what stage should I apply this GOW C-Deep Vitamin C Serum?
We suggest that you apply a sufficient amount of vitamin C serum to cover the face onto cleansed, dry skin, ideally at night.  This should be the last step on clean skin after other products are used. 

How should I store GOW C-Deep Vitamin C Serum?
In order to preserve this serum, we suggest you store in a cool dark place. 

Can I use GOW C-Deep Vitamin C Serum in the day?
If using in the day follow with an SPF. 

I cannot seem to get the product out?  It will not pump.  Why is this?
Sometimes the pumps can get an air bubble or blockage, and if you bang the container really hard on a hard surface a few times this normally clears it. 

What is the difference between Vitamin C 23% & C-Deep?
You cannot directly compare the two vitamin C serums as one contains the acidic form of vitamin C, L-ascorbic acid and the other contains a derivative of vitamin C called Tetrahexyldecyl ascorbate.  Vitamin C 23% Serum works to quickly brighten and freshen skin appearance whilst also working to enhance collagen synthesis.  C-Deep contains the non-acidic vitamin C which works gradually to lighten and freshen skin's appearance but it does penetrate deeper and so it works quicker to enhance collagen synthesis - it is suitable for all skin types including sensitive skin.  C-Deep is based in squalane oil.  Vitamin C 23% is more of a serum and is not oil based. 

Is GOW C-Deep Vitamin C Serum suitable for sensitive skin?
This should be suitable to use on sensitive skin. 

Why is C-Deep oily?
C-Deep is suspended in Squalane, a light oil that is easily absorbed into skin.
