Ole Hendrikson's Truth Serum Collagen Booster is my FAV vitamin C serum.
Why? Because it is 10% vitamin C and actually absorbs into my skin,
unlike others that leave a suffocating film.
I took advantage of the kits at Sephora because they are a much better deal. They both come with a 1 oz bottle of Truth Serum, which is $48 USD/$60 CAD by itself at Sephora.
The Celebrate the Truth Set for $60USD (I bought this in the US so I do not have the Canadian price) contains:
1 oz Truth Serum
1 oz Truth Creme Advanced Hydration
0.25 oz Truth is in the Eyes
10 Truth to go wipes
The 3 Little Wonders Set for $70USD/$84CAD contains:
1 oz Truth Serum
1 oz Invigorating Night Gel
1 oz Sheer Transformation
I have not tried the other products in the set yet, but I have already used up 1.5 bottles of the Truth Serum since fall 2012. If you do not already know, using a vitamin C serum not only boosts the effects of your sunscreen, but it is one of the few ingredients actually proven to help prevent collagen loss by combating free radical damage, thus preventing skin aging. It will also help brighten your skin and help with pigmentation and dark spots. Of course, not all vitamin C serums are created equally. It depends on the form of vitamin C used and the percentage of the vitamin C. The strength of the vitamin C should be at least 10% to be effective, otherwise it will do nothing for your skin. Although it is not indicated on the bottle, I was told by the company that Truth Serum is 10% vitamin C.
Ingredients in Truth Serum:
Water (Aqua), Sodium Ascorbyl Phosphate, Calcium Ascorbate, Sorbitol, Glycerin, Tocopheryl Acetate, Aloe Barbadensis Leaf Juice, Citrus Aurantium Dulcis (Orange) Fruit Extract, Camellia Sinensis Leaf Extract, Euphrasia Officinalis Extract, Rosa Canina Fruit Extract, Citrus Grandis (Grapefruit) Seed Extract, Oleth-20, Hydroxyethylcellulose, PEG-12 Dimethicone, Benzophenone-4, Sodium Hyaluronate, Thioctic Acid, Phenoxyethanol, Citric Acid, Caprylyl Glycol, Hexylene Glycol, Limonene, Linalool, Citral, Fragrance (Parfum), Yellow 6
As you can see, the second ingredient is Sodium Ascorbyl Phosphate. There are many forms of vitamin C, and they vary in their stability. The more stable the vitamin C is, the better it is for your skin. L-ascorbic acid is the most common type seen in cosmetics. Sodium Ascorbyl Phosphate is a newer derivative, so it is not as common, but the stability is touted to be better than L-ascorbic acid. Most vitamin C serums are packaged in dark, amber bottles to prevent light from damaging the vitamin C. Since Sodium Ascorbyl Phosphate is more stable, it does not have to be suspended in a silicone or propylene glycol base, which leaves a film on the face. It is also the reason why it can be packaged in a clear bottle in a watery base, although I still prefer an amber bottle.
Next on the ingredient list is Calcium Ascorbate, which is a naturally occurring form of vitamin C, and also very stable.
The other ingredients in the formulation aren't anything special, except maybe Sodium Hyaluronate, which will help with skin hydration.
I use this serum morning and night. In the morning, I use one pump underneath my sunscreen. Be careful not to use too much, otherwise it will feel sticky on the skin. As mentioned previously, the vitamin C will work with my sunscreen to increase sun protection. At night, I use one pump underneath my night time moisturizer or sleeping pack. It is important to use it at night because this is when your skin will reap the antioxidant benefits.
I have also used this product around my eyes with no issues, but I do not go too close and be cautious if you have sensitive eyes.
I don't like that they added orange colour to the product. I know it is probably to go along with the pleasant orange scent, but it is unnecessary. Usually you know a vitamin C serum has gone bad when it turns orange. Btw, you should NEVER use a vitamin C serum that has gone bad, because it can do more damage than good. I guess because of the stability of this product they felt confident to add coloring to it. Not a fan though. They also need to make a better pump. Sometimes it gets stuck or squirts out too much product.
I have noticed with daily use of this product my complexion is brighter. PLEASE, even if you stop seeing the effects, do not stop using it because it is preventative, NOT corrective. Meaning, even if you are not seeing effects, the vitamin C is still protecting your skin.
