A super-light, water-like 15% Vitamin C + extra antioxidants (Ferulic Acid & a smaller amount of Vitamin E) formula to give the skin environmental protection, boost collagen & even the skin tone.
C-Glow 15% Vitamin C Serum is a watery-light serum from Geek & Gorgeous, a brand based in Hungary. The formula is built mainly around antioxidant protection. The ingredient list runs to 10 ingredients, each broken down in full below.
By its ingredient list the formula reads as very light — essentially a water-and-humectant base with little emollient weight. With almost no emollient load it should absorb quickly and finish close to matte.
Antioxidant support: High. Ingredients that mop up free radicals from UV and pollution, and here that comes from Ascorbic Acid, Ferulic Acid and Tocopherol.
Hydration: Moderate. Ingredients that pull and hold water in the upper layers of skin, and here that comes from Butylene Glycol, Peg/ppg/polybutylene Glycol-8/5/3 Glycerin and Ethylhexylglycerin.
Brightening: Moderate. Ingredients that act on uneven tone and post-inflammatory marks, and here that comes from Ascorbic Acid and Tocopherol.
On richness alone it suits Combination (oily) and Oily skin best, and is the least natural fit for Dry and Combination (dry) skin. Nothing in the list is flagged as a common irritant, which is a reasonable starting point for reactive skin — though a patch test is still the only way to know.
The formula contributes little or nothing on barrier support, oil control, cell renewal and firmness signalling. That is not a fault — most products are not meant to do everything — but if one of those is your priority, this is not the product that will address it.
Reading the full list, the formula is fragrance-free, essential-oil-free, no drying alcohol, paraben-free, silicone-free and microplastic-free. Those claims come from the ingredient list itself, not from the packaging.
It can be used morning and evening. In a routine it goes after toner, before moisturiser. Apply to clean, dry skin and give it a minute to absorb before the next layer. Introduce one new treatment at a time so you can identify what is working.
This summary is generated from the product's ingredient list. It is not a review, it is not the brand's own marketing claims, and it does not replace advice from a dermatologist.
