Take the skin testTargeting your skin’s unique needs is as easy as A, B, C, thanks to Alpha-H’s ultra-customisable (not to mention effective) range of vitamin-focused treatments. Looking to tackle dullness, hyperpigmentation and unwanted texture? Let us introduce you to the Vitamin C Serum. Lightweight and hydrating, this silky serum uses 10% ethyl ascorbic acid, an impressively stable form of (the infamously unstable ) vitamin C that evens skin tone and seriously ups the ante on your radiance, all while imbuing your skin with antioxidants that protect against damage from free radicals. This superstar is surrounded by an exceptional supporting cast. Think: soothing liquorice extract, anti-inflammatory tazman pepper and fatty acid-rich grape seed oil.
Vitamin C Serum with 10% Ethyl Ascorbic Acid is a watery-light serum from Alpha-H, a brand based in Australia. The formula is built mainly around hydration. The ingredient list runs to 20 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. Hydration is handled by Propanediol, Glycerin and Sodium Hyaluronate, humectants that pull water into the upper layers of skin rather than sealing it there.
Hydration: High. Ingredients that pull and hold water in the upper layers of skin, and here that comes from Propanediol, Glycerin, Sodium Hyaluronate and Methyl Gluceth-20.
Brightening: Moderate. Ingredients that act on uneven tone and post-inflammatory marks, and here that comes from 3-o-ethyl Ascorbic Acid and Glycyrrhiza Glabra Root Extract.
Antioxidant support: Moderate. Ingredients that mop up free radicals from UV and pollution, and here that comes from 3-o-ethyl Ascorbic Acid.
On richness alone it suits Combination (oily) and Oily skin best, and is the least natural fit for Dry and Combination (dry) skin. A few ingredients carry irritation flags, so reactive skin should patch test before using it on the whole face.
The formula contributes little or nothing on barrier support, oil control 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 no drying alcohol, paraben-free, silicone-free, microplastic-free, sulfate-free and oil-free. Those claims come from the ingredient list itself, not from the packaging. It does contain fragrance and essential oils, worth knowing if your skin reacts to any of them.
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.
