Take the skin testThe Dr.Althea Aqua Blue Hydration Mask is an intensely hydrating sheet mask designed to replenish moisture, soothe dryness, and restore a fresh, dewy complexion. Infused with moisture-binding ingredients and calming actives, this mask helps deliver deep hydration while cooling and comforting the skin. Its soft, skin-hugging sheet ensures even distribution of essence for optimal absorption. Ideal for dehydrated or stressed skin, this mask helps improve moisture balance, smooth texture, and enhance natural radiance.
Aqua Blue Hydration Mask is a watery-light sheet mask from Dr. Althea, a brand based in Korea. The formula is built mainly around hydration. The ingredient list runs to 24 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, Glycerin and Ethylhexylglycerin, 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, Glycerin, Ethylhexylglycerin and Water.
Soothing: Moderate. Ingredients aimed at visible redness and reactivity, and here that comes from Allantoin, Niacinamide, Adenosine and Azulene.
Oil control: Moderate. Ingredients that moderate sebum or absorb shine, and here that comes from Niacinamide and Maltodextrin.
Brightening: Moderate. Ingredients that act on uneven tone and post-inflammatory marks, and here that comes from Niacinamide 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 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 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.

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.
