Dammall Hyaluronic Acid

Hyaluronic acid's function on skin changes significantly with molecular weight. High molecular weight (standard and polymer) forms a film on the skin surface, binding water at the outer layers and providing the immediate plump, hydrated look that most topical serums aim for. It does not penetrate the stratum corneum well, but it is highly effective for surface moisture retention and texture. Low molecular weight hyaluronic acid is small enough to pass into deeper epidermal layers, where it supports the skin's own moisture matrix more durably. Ultra-low molecular weight goes even further, targeting the dermis boundary zone, though this form is rarer in finished-product serums. Dammall sells all three tiers as 1% solutions, so you can choose the depth of action that suits your formulation or routine intent.

Dammall Polymer Hyaluronic Acid 1% Solution comes in 100ml, 500ml, and 1000ml sizes, including a raw solution variant. Polymer hyaluronic acid is a cross-linked or high-molecular-weight form that stays at the skin surface longer than standard HA, providing extended film-forming and a thicker gel texture. In finished serums this gives the 'bouncy' skin feel associated with Korean hydration layers. For DIY use, the polymer form adds viscosity and a plumping effect. Use it in leave-on serums, essences, or as a hydrating ampoule base; it blends well with water-phase ingredients at pH 5-7.

The Dammall Low Molecular Weight Hyaluronic Acid 1% Solution comes in 500ml and 1000ml undiluted formats, plus a 100ml personal-use size. LMW-HA is fragmentized to pass through the outer skin barrier and carry moisture into the upper dermal layers. This makes it more appropriate for formulations targeting skin that feels tight or lacks elasticity over time rather than just surface dryness. In a layering routine, LMW-HA applied first (as a watery essence) allows it to act at depth before a film-forming high-MW product is layered on top.

The Dammall Ultra-low Molecular Weight Hyaluronic Acid Solution 100ml is the smallest-molecular variant in the range. Ultra-LMW HA (often listed as nano-HA or oligo-HA in finished products) is fragmented to under 10 kDa, enabling reported penetration into the dermis. Clinical evidence at this size is still developing, but it is commonly used in professional-grade ampoules and high-end serums for long-term skin density support. At 100ml in Dammall's line, this is a personal-use or small-batch formulation size.

Dammall sells both. The 1% Solution products (e.g., Hyaluronic Acid 1% Undiluted 100ml, Low Molecular Weight Hyaluronic Acid 1% Solution 500ml) are pre-dissolved in water at 1% concentration and can be used directly on skin or added to formulations without further dilution. The raw solution variants (Polymer Hyaluronic Acid 1% raw solution 100ml and 1000ml) are also at 1% but labeled as raw/formulator stock to indicate they are intended for downstream mixing rather than direct consumer skin application. In practice, a 1% HA solution is a typical serum-strength ingredient and is generally safe to apply directly; the raw labeling is a trade convention. If you are formulating a product at a specific concentration, starting from a 1% pre-dissolved solution is more consistent than hydrating dry HA powder yourself.

The 100ml bottles are personal-use or small-batch formulation sizes - enough for weeks of daily serum use or a modest DIY batch. The 500ml bottles suit either regular household skincare (one or two people applying a solution daily for six or more months) or small-production cosmetics batches. The 1000ml sizes are bulk formulation stock, appropriate for semi-professional use, group or family supply, or split across multiple small bottles. The Hyaluronic Acid 1% Undiluted starts at 100ml; Low Molecular Weight goes up to 1000ml; Polymer covers 100ml to 1000ml with raw and solution variants at each tier.

The Dammall 4 Kinds of Steamed Hyaluronic Acid Water Light Moisture Ampoule Making Kit bundles four molecular weight variants in one purchase. This kit is aimed at home formulators who want to compare the texture and feel of standard, polymer, low-MW, and ultra-low-MW HA in their own skin without buying four separate full bottles. It is also a cost-efficient entry point for blending experiments before committing to larger single-type volumes. The 'steamed' designation in the Dammall naming refers to the water-light ampoule texture profile rather than a steam-applied process.

Apply Dammall HA solutions on clean, slightly damp skin before heavier creams or oils. HA works as a humectant - it draws water to itself - so applying it to damp skin (or in a humid environment) gives it moisture to bind; applying to completely dry skin in a low-humidity environment can draw moisture from deeper layers, which is counterproductive. In a layering routine, low-MW HA goes first, then standard or polymer HA over the top, then a moisturizer or cream to seal. In a DIY formulation, add HA to the water phase during cool-down or at room temperature; sustained heat can degrade the chain length and reduce effectiveness.

Dammall's 1% solutions are pH-buffered for skin compatibility but work best at a final product pH of 4.5-6.5. High-MW and polymer HA adds viscosity to a formulation; if you want a watery serum texture, use LMW or ultra-LMW. Polymer HA at 1% will thicken water-phase formulations noticeably. Combine with niacinamide, panthenol, or glycerin for layered humectant effect. Avoid high heat during formulation. If adding a preservative, use one compatible with pH 5-6.5 and aqueous systems.
