Take the skin testDr. Althea Vitamin C Boosting Serum is a lightweight, radiance-enhancing formula designed to achieve clear, glowing skin. Featuring 63% Hippophae Rhamnoides Water, it delivers powerful brightening and antioxidant benefits, while triple hyaluronic acid ensures optimal moisture balance and long-lasting hydration. Infused with niacinamide, tranexamic acid, and Centella Asiatica extract, the serum works to improve skin tone, calm irritation, and strengthen the skin barrier. The addition of Ceramide NP, Adenosine, and a blend of botanical extracts further supports skin health, leaving it smooth, hydrated, and visibly radiant. Ideal for all skin types, this serum is a must-have for a luminous complexion.
Vitamin C Boosting Serum is a watery-light serum from Dr.Althea. The formula is built mainly around hydration and soothing. The ingredient list runs to 42 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 Butylene Glycol, Methylpropanediol and Betaine, 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 Butylene Glycol, Methylpropanediol, Betaine and Glycerin.
Soothing: High. Ingredients aimed at visible redness and reactivity, and here that comes from Centella Asiatica Leaf Water, Centella Asiatica Extract, Panthenol and Beta-glucan.
Brightening: Moderate. Ingredients that act on uneven tone and post-inflammatory marks, and here that comes from Niacinamide, Tranexamic Acid, 3-o-ethyl Ascorbic Acid and Ascorbic Acid.
Barrier support: Moderate. Lipids and repair signals that support skin barrier integrity, and here that comes from Niacinamide, Hydrogenated Lecithin, Panthenol and Ceramide NP.
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 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.
Drawn purely from the ingredient list
Scored on how rich or light the formula reads from its INCI order.
No ingredient in this formula carries a common-irritant flag, making it a reasonable option for reactive skin. A patch test is still recommended, as individual skin reactivity varies.
Based on the curated benefits documented for this product's ingredients.
Attracts and locks in moisture to keep skin plump and dewy
Boosts collagen and cell turnover to reduce fine lines and wrinkles
Calms redness, irritation, and inflammation for sensitive skin
Brightens and balances complexion for a more uniform appearance
Fades hyperpigmentation and evens out dark spots over time
Tightens and refines the look of enlarged pores
None of the ingredients in this formula are associated with these benefits. This is not unusual, as most products are designed to target a limited number of concerns.
