Fit by skin type
General, ingredient-based — not your personalized match.
See how this fits your skin
Take the skin test and I'll show you how suitable this product is for you.
Take the skin testDive into ultimate hydration with the EQQUALBERRY Hyaltoin Flooding Serum, a refreshing hydration bomb infused with 50,000ppm Hyaltoin™ complex for multi-layered, long-lasting moisture that plumps and revives dehydrated skin. This innovative formula combines 11 types of hyaluronic acid in varying molecular sizes to penetrate deeply, paired with powerful ectoine for environmental protection and 5 ceramides to reinforce the skin barrier. Enriched with brightening niacinamide to help fade hyperpigmentation and even out skin tone, plus soothing panthenol and squalane for a calm, dewy glass-skin glow. Lightweight, non-sticky texture with visible ceramide flakes melts instantly, delivering an icy-cool surge of glacier water freshness, perfect for achieving that juicy, radiant K-beauty finish without irritation.
Hyaltoin Flooding Serum is a lightweight serum from Eqqualberry, a brand based in Korea. The formula is built mainly around hydration and soothing. The ingredient list runs to 62 ingredients, each broken down in full below.
By its ingredient list the formula reads as light: water and humectants lead, with emollients kept lower in the order. Hydration is handled by Butylene Glycol, Glycerin and Betaine, humectants that pull water into the upper layers of skin rather than sealing it there.
Hydration: Very high. Ingredients that pull and hold water in the upper layers of skin, and here that comes from Butylene Glycol, Glycerin, Betaine and Sodium Hyaluronate.
Soothing: High. Ingredients aimed at visible redness and reactivity, and here that comes from Cetyl Ethylhexanoate, Ectoin, Panthenol and Allantoin.
Barrier support: Moderate. Lipids and repair signals that support skin barrier integrity, and here that comes from Niacinamide, Hydrogenated Lecithin, Ceramide NP and Ceramide NS.
On richness alone it suits Balanced 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 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.
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.
Based on the curated benefits documented for this product's ingredients.
Attracts and locks in moisture to keep skin plump and dewy
Boosts collagen and cell turnover to reduce fine lines and wrinkles
Calms redness, irritation, and inflammation for sensitive skin
Brightens and balances complexion for a more uniform appearance
Regulates sebum production to reduce shine and greasiness
Tightens and refines the look of enlarged pores
None of the ingredients in this formula are associated with these benefits. This is not unusual, as most products are designed to target a limited number of concerns.

Solvents, emollients, texture agents and preservatives — the formula that carries the actives.
Read from the full ingredient list. A brand's own claim may differ.
Judged by the same curated rules our routine checker uses. It reads the ingredients, not the label.
Nothing in this formula belongs to a group our rules can put in conflict, so it layers freely. Order still matters — thinnest texture first.
This product is the "Treat" step.
Flags to check, not verdicts. None of this is medical advice — if you are pregnant, breastfeeding or treating a skin condition, ask a doctor.
Most ingredients do more than one job, so these counts add up to more than the 62 ingredients on the label.

Botanical material, usually for antioxidants or scent
Changes how skin behaves rather than how it feels
Sets the thickness, spread and stability of the formula
Softens and smooths by filling gaps between skin cells
