Ingredients Concern: Imidazolidinyl Urea, (a formaldehyde releaser), Phenoxyethanol (safe in small quanitities), Retinol Palmitate (Vitamin A Palmitate) -( this ingredient should not be used during the day as retinol looses effectiveness as soon as it hits light. There are also health concerns with continual use.
Stability of this Vitamin C as with many topical Vitamin products has not been scientifically proven for most brands , which means it most likely degrades quickly when exposed to light and air. However, the hyaluronic acid may still provide a great benefit.
Effectiveness of this Vitamin C derivative Sodium Ascorbyl Phosphate (Vitamin C) has not been proven in human studies in peer reviewed respected scientific journals in converting to acsorbic acid within the skin in amounts necessary to see any results.
Does not contain Ferulic acid or sodium metabisulphite (ingredients that help stabilize Vitamin C), but does contain Vitamin E
Contains Sodium Ascorbyl Phosphate (Vitamin C), a derivative of Vitamin C that has NOT been proven in human studies to show anti-aging benefits.
This should not contain Retinol Palmitate (Vitamin A Palmitate) because retinol is ineffective in daytime as soon as it reaches sunlight. It is rated an ingredient of high concern by EWG due to developmental and reproductive toxicity (9/10).
Imidazolidinyl Urea, (a formaldehyde releaser) is in this Claire-ity serum and it is rated 5/10 on EWG because of studies that show it caused allergies and immunotoxicity.
Consult a dermatologist before use, Always test out your skin's sensitivity by applying a small amount to the inside of your wrist first, For external use only, Avoid contact with eyes, If skin sensitivity occurs or if you suspect an allergic reaction, stop use and consult your doctor, Keep out of reach of children and animals, Phenoxyethanol has an EWG score between 2-4, depending on its usage Triethanolamine an EWG score between 2-4, depending on its usage
Claire-ity serum contains Sodium Ascorbyl Phosphate (Vitamin C) which is a derivative of Vitamin C. There is not sufficient scientifical evidence in respected peer review journals to prove that this form of Vitamin C produces anti-aging results.
For example, one study stated that "It should also be mentioned that there is an increasing number of ascorbic acid-based topical cosmetics available on the market, and it seems that not all preparations of topical ascorbic acid are effective. Many of these products use derivatives, esters, and analogs of ascorbic acid that do not penetrate the skin, do not chemically convert to L-ascorbic acid (the only form that can be used by the body), and/or are not delivered in adequate concentration. These ascorbic acid substitutes include ascorbyl palmitate, magnesium ascorbyl phosphate, ascorbic acid sulfate, ascorbyl stearate, ascorbyl dipalmitate, and ascorbic acid magnesium phosphate, which are easily stabilized but must be converted to L-ascorbate to be effectively useful. There is no direct evidence that ascorbic acid derivatives enter the skin in appreciable amounts, and it seems that their conversion to L-ascorbate is largely inefficient, thus precluding effective concentration delivery. 
Another scientific study also reinforced that "Formulations containing derivatives of ascorbic acid have been found to be more stable, but they DO NOT produce the same effect as that of the parent compound." 
Because Vitamin C is not stable, as it degrades when it comes into contact with light or air, there is a huge question as to whether it will really produce anti-aging benefits for your skin. Note that products may sit in hot warehouses, go through extensive shipping and have the potential to degrade due to heat. Derivatives have been theorized to have more stability than ascorbic acid, yet this is not certain and some tests show that many derivatives are not stable. However, note that the hyaluronic acid in this serum may provide a nice benefit to the skin in terms of hydration. Hyaluronic acid has proven moisturizing properties that are beneficial for the skin .(D-alpha Tocopheryl Acetate) helps improve firmness and skin tone, thereby targeting the signs of premature aging . H Aloe barbadensis boosts the body's natural wound-healing processes [6,7].
If this form of Vitamin C derivative in this serum does effectively convert into ascorbic acid and work, and it remains stable -- then we may consider looking at the results that have been shown for ascorbic acid.Vitamin C is a potent antioxidant with UV photoprotective properties [1, 2], and also promotes skin regeneration after damage (3). Hyaluronic Acid promotes water retention that helps hydrate the skin . Green tea contains the antioxidant epigallocatechin-3-gallate (EGCG) that fights UV-induced DNA damage in order to protect against skin damage . Vitamin E helps reduce skin roughness, wrinkle depth, the length of facial lines, and hyperpigmentation. Vitamin E oil helps create a protective barrier on the surface of the skin [5,6].
