Take the skin testThe Dr.Althea 345 Relief Cream Mask is a specialized sheet mask designed for rapid skin recovery and blemish relief. Built as a concentrated version of the brand’s cult-favorite 345 Relief Cream, this mask features a unique "3-4-5" formulation strategy: 3 blemish-relief ingredients, 4 nourishing ingredients, and 5 soothing care components. It utilizes 30% Tea Tree Leaf Water and three different Centella-derived extracts to reduce redness and inflammation significantly. The essence is delivered via a high-adherence vegan cellulose sheet, which ensures that the active ingredients are absorbed deeply into the skin without leaving a heavy residue. It is particularly effective for post-acne care, helping to fade marks and repair the skin barrier.
345 Relief Cream Mask is a watery-light sheet mask from Dr.Althea. The formula is built mainly around hydration. The ingredient list runs to 37 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 Methylpropanediol, Butylene Glycol and Glycerin, 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 Methylpropanediol, Butylene Glycol, Glycerin and Trehalose.
Soothing: Moderate. Ingredients aimed at visible redness and reactivity, and here that comes from Allantoin, Panthenol, Centella Asiatica Leaf Water and Centella Asiatica Extract.
Barrier support: Moderate. Lipids and repair signals that support skin barrier integrity, and here that comes from Niacinamide, Panthenol, Pantothenic Acid and Hydrogenated Lecithin.
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 serums. Seal in your serums with it; in the morning, sunscreen still goes on top.
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.
