MULTI-MOLECULAR HYALURONIC ACID SERUM

I layer after Vitamin C serum and before moisturizer. Seamless layering.

My skin drinks this up. Within minutes I can see my fine lines plump out.

Three bottles in and I'm never going back to my old HA serum.

I live in a dry climate and this is the only serum that keeps me hydrated past noon.

What skin concerns does this serum address?
Dryness, dehydration, and loss of plumpness. Five molecular weights of hyaluronic acid hydrate every layer of skin while polyglutamic acid and snow mushroom seal and extend that moisture.
Can I use this serum with vitamin C or retinol?
Yes — it layers with virtually everything, including vitamin C, retinol, and exfoliating acids, and helps buffer their dryness.
How often should I apply this serum?
Morning and night, 2–3 drops on clean, slightly damp skin — then seal with moisturizer while skin is still tacky.
Is this serum suitable for oily or blemish-prone skin?
Yes — it's a weightless, oil-free, water-based formula that hydrates without clogging pores.
How long does it take to see results with this serum?
Plumping is visible within minutes as the surface rehydrates; deeper improvement in dehydration lines builds over 2–4 weeks.
Are the ingredients in this serum clean and safe?
Yes. The Multi-Molecular Hyaluronic Acid Serum is formulated without synthetic fragrance, parabens, sulfates, phthalates, dyes, silicones, PEGs, MCI/MI, DEA, BHA/BHT, triclosan, lanolin, talc, petrolatum, mineral oil, and formaldehyde-releasing preservatives. Cruelty-free — never tested on animals. Every formula is made in the USA in an FDA-registered, ISO 22716–certified facility that is cGMP and MoCRA compliant.
