The skin care product, Glowic, contains the antioxidants vitamin C and vitamin E, along with ferulic acid to potentiate their effects. It also has vitamin B3 (niacinamide) as a stabilizer and moisturizer, vitamin B5 (panthenol) as a humectant and conditioner, hyaluronic acid as a powerful humectant, sodium PCA as a hydrating ingredient, and glycerin as a humectant and conditioner. The concentration of ingredients is not stated. The paper they cite studying topical vitamins Cand E as augmented with ferulic acid, used 150 mg per ml of vitamin C. That paper cited a study showing that maximal absorption of acidic vitamin C in pig skin (often used as a human-like model) occurred with a 200 mg per ml solution. How effective would Glowic be in a side-by-side comparison with Vitablosom Liposomal Vitamin C (containing 2000mg in a 2 ml volume) for treating age spots, given the latter has 1000 mg per ml in a liposomal formulation designed to enhance stability and bioavailability?

Glowic is designed with a perspective that more is better, from the inclusion of multiple ingredients with a track record of use for skincare products because of the stated properties being advantageous. This creates an aura of greater power, being a more comprehensive array of nutraceuticals, but that does not mean that all ingredients are necessary and major contributors. We think that a side-by-side comparison would show the liposomal vitamin C formulation you have used topically will be very difficult to distinguish from the best that Glowic can achieve. In other words, see the Vitablossom product as superior with the Glowic a close second, on average. There are always individual circumstances where one or the other might edge out the competition because of differing skin makeup and state of degradation underway. So the question comes down to more one of personal preference and cost considerations.
