Take the skin test and I'll show you how suitable this product is for you.
Take the skin testDr. Althea’s Multi Action Infusion Serum is a lightweight, fast-absorbing formula designed to instantly revitalize dry, tired, and dull skin. Infused with six types of Hyaluronic Acid for deep hydration and a powerful blend of five key ingredients Noni Extract, Centella Asiatica Extract, Betaine, Niacinamide, and Adenosine, it strengthens the skin’s immune system and promotes overall skin health. This vegan, EWG Green Grade serum contains no artificial coloring or fragrance, making it a gentle yet effective choice for achieving a radiant, well-nourished complexion.
Multi-Action Infusion Serum is a watery-light serum from Dr.Althea. The formula is built mainly around hydration. The ingredient list runs to 25 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 Sodium Hyaluronate.
Soothing: Moderate. Ingredients aimed at visible redness and reactivity, and here that comes from Centella Asiatica Extract, Niacinamide, Adenosine and Sodium Hyaluronate.
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 antioxidant protection, 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 essential-oil-free, no drying alcohol, paraben-free, silicone-free, microplastic-free and sulfate-free. Those claims come from the ingredient list itself, not from the packaging. It does contain fragrance, 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.
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.
