What it is
If you have hay fever, you already know that the problem isn't just the sneezing — it's the fact that pollen lands on your face, gets into your eyes and nose all day, and by spring's end your skin is irritated, dry, and reactive from months of constant exposure. Aller-Shut's approach is unusually practical: the mist uses a cationic polymer (positively charged ion) that coats the face and hair on contact, creating an invisible barrier that repels and absorbs airborne pollen particles, PM2.5, and yellow dust before they can reach the eyes, nose, and mouth. The key distinction with this Makeup Keep version is that it's specifically formulated to go over a finished face of makeup without disrupting it — it also contains a makeup coat component that actually helps set and prolong wear. Three moisturising ingredients (Hyaluronic Acid, Ceramide, and Glycosyl Trehalose) are included to counteract the drying effect that pollen season reliably inflicts on skin. Fragrance-free, alcohol-free, mineral oil-free, colorant-free, and silicone-free, with patch and sting testing completed. A genuinely clever product that sits at the intersection of health and beauty — one step that does three jobs before you leave the house.
Ingredients
(1) Cationic Polymer (Positively Charged Ion): the active barrier component — coats the face and hair with an invisible ionic layer that repels and absorbs negatively charged pollen particles and PM2.5
(2) Hyaluronic Acid Na: a humectant that draws moisture to the skin surface to counteract the dehydrating effect of pollen-season environmental exposure
(3) Ceramide (Rice Bran Sphingoglycolipid): helps maintain the skin's lipid barrier — particularly important during allergy season when repeated exposure to allergens can compromise skin integrity
(4) Glycosyl Trehalose: a moisturising saccharide that supports skin barrier conditioning and water retention
(5) Makeup Coat Component: helps lock the appearance of makeup in place after spraying, preventing mid-day breakdown
How to use
After completing your makeup routine, hold the bottle approximately 20–30cm from the face and spray 2–3 times in a sweeping motion to cover the entire face evenly. Close your eyes while spraying and allow the mist to settle naturally — no need to rub or blend in. For hair and the back of the neck, spray from a similar distance and allow to dry. Reapply before heading back outside after being indoors. Can also be used on bare skin before applying makeup, or on children's faces (aged 3+) before going outdoors during pollen season. Shake gently before each use.
