The Problem
Your routine is consistent. The shine still comes back by midday.

A good cleanser and a light moisturiser should be enough, yet some skin keeps looking slick and uneven through the day. When basic steps stop being enough, you start reading labels for a formula built around a more specific active, not just another hydrating sheet.

The Answer
ALA Mask Omega Light Advanced Sebum Control
A box of 10 single-use sheet masks built around aminolevulinic acid.

Aminolevulinic Acid HCl leads the formula, supported by salicylic acid for a smoother surface, allantoin for comfort, and aloe, squalane, shea butter and ceramide 3 to keep the finish soft and cushioned. It is a focused, short-course format for skin that looks shiny and feels congested.

What You Feel First
During the mask
A cool, essence-soaked layer that sits comfortably on the face, with a light, clean finish.
Next morning
Skin feels smoother and calmer to the touch, with a more matte, even surface.
The Concern We Hear Most
"Sheet masks all promise the same thing. What is actually in this one?"

A fair question. Aminolevulinic Acid HCl is the lead active and the reason this mask sits in a category of its own. Salicylic acid refines the look of texture, allantoin keeps skin feeling comfortable, and ceramide 3, squalane and shea butter soften the finish. The formula also contains alcohol and a UV-filter ingredient, Ethylhexyl Triazone. Every ingredient is listed in full on this page, so you can read the formula yourself.

The Ingredients Behind It
Aminolevulinic Acid HCl Lead active
The hero ingredient of this mask and the reason for its name, formulated for shine-prone, congested skin.
Salicylic Acid Texture
A familiar BHA that refines the look of texture and leaves the surface feeling smoother.
Allantoin Comfort
A gentle, softening ingredient that keeps skin feeling comfortable during and after the mask.
Ceramide 3 + Squalane Cushion
A skin-identical lipid and a light oil that give the finish a soft, supple feel.
Formulated with these concerns in mind
Midday shine
Uneven texture
Congested skin
More Than a Sheet Mask
One active, read in full, before it touches your skin.

Ten sheets give you a defined routine for the weeks when shine and texture need extra attention. No guesswork, no open-ended bottle.

Every ingredient is on the page, and every one can be checked. If you read labels before you buy, this is the formula that holds up.

Why Our Pharmacist Chose This

“Aminolevulinic acid HCl, salicylic acid and allantoin lead the named ingredients in a list that is easy to read. Alcohol is listed, so patch test first if your skin is reactive.”
