Hyaluronic Acid 0.3% Hydrating Booster

HELLO HYDRATIONThis all-natural Hyaluronic Acid booster gives your routine a serious hydration boost. It's a concentrated dose of one of skincare's most reliable humectants, the kind that pulls moisture in and refuses to let it go. By hydrating skin at different depths, it supports a stronger barrier and a healthy glow.Inside this small but mighty bottle, three distinct molecular weights of Hyaluronic Acid work in tandem, each sourced from maize via bacterial fermentation. The largest molecules form a protective film right at the surface, the mid-sized ones build a moisture reservoir through the upper epidermis, and the smallest reach into the deeper epidermal layers. The payoff? An uninterrupted moisture gradient that helps protect skin against transepidermal water loss.HA isn't the whole story here. Hydrolyzed Glycosaminoglycans go deeper still, extending hydration further into the skin, while Blueberry Seed Oil and Avocado Oil bring omegas and antioxidants that reinforce the barrier and keep moisture from escaping. Prebiotic Inulin nourishes the friendly bacteria on the skin's surface, helping the microbiome stay in balance.Now, about those percentages. Plenty of brands brag about 2%, 5%, even 10% HA. The research disagrees. Published studies have found that even 0.1% HA can drive real gains in hydration, elasticity, and wrinkle depth. At 0.3%, every molecular weight is fully dissolved, bioavailable, and working in concert within a lightweight feel that disappears into whichever moisturizer is already in your routine. No pilling under makeup, no tacky residue, no inflated marketing numbers.From our Pai Labs Booster lineup, where each formula delivers a single concentrated active to elevate your routine without triggering irritation. Add 1-2 drops to whichever moisturizer you already trust, morning or evening. Why You'll Love It Directions Full Ingredients Recycling How do I use this booster? Add 1-2 drops into your moisturiser (any brand works) and apply as normal. You can use it morning, evening, or both. It's a booster, not a replacement, so it slots into your existing routine without adding an extra step. What skin types is this suitable for? All of them. It's designed for dry, combination, normal, and sensitive skin. The formula is non-comedogenic, so it won't clog pores, and every batch undergoes 96-hour human repeat insult patch testing to confirm it won't trigger irritation, even on reactive skin. What is this booster free from? The formula is free from fragrance, essential oils, alcohol, parabens, silicones, sulfates, mineral oil, phthalates, dyes, wheat, and gluten. It's 100% natural origin ingredients, COSMOS Natural certified, and contains nothing that would flag as a concern for sensitive or reactive skin types. Is it safe to use during pregnancy and breastfeeding? Yes, this booster is confirmed safe for use during pregnancy and breastfeeding. It's 100% natural, free from essential oils and fragrance, and contains no ingredients flagged as concerns for expectant or nursing mothers. Can I use this booster with other Pai Labs Boosters at the same time? Yes. Each Pai Labs Booster delivers a single focused active, so you can combine them by adding drops of different boosters into the same moisturiser application. For example, pairing the Hyaluronic Acid Booster with the Peptides or Vitamin C Booster lets you target hydration alongside other concerns in one step. Why only 0.3% hyaluronic acid when other brands use 2% or more? Higher isn't better here. Sodium hyaluronate is a powder that forms a thick gel in water, so above roughly 1% it becomes goopy and difficult to use. Published clinical research (Pavicic T. et al., 2011) shows that just 0.1% HA applied twice daily produced around 10% more hydration, 20% more elasticity, and 10% wrinkle depth reduction. At 0.3%, all three molecular weights are fully dissolved, bioavailable, and delivered in a texture that actually works on skin. What do the supporting oils in the formula do? Blueberry seed oil delivers omega-3 and omega-6 fatty acids plus tocotrienols (a potent form of vitamin E) that help protect against free radical damage, while staying lightweight and non-greasy. Avocado oil provides vitamins A, D, and E alongside omega fatty acids that closely resemble your skin's own sebum, reinforcing your barrier and helping prevent moisture from escaping. How is the hyaluronic acid in this booster sourced? It's produced by bacterial fermentation from maize glucose, not derived from animal sources. The process is COSMOS certified, meeting the strictest standards for natural cosmetics. The entire formula is vegan, cruelty-free (Leaping Bunny certified), and made in Pai's London lab. Who should choose this booster over a standalone hyaluronic acid serum? Anyone who wants multi-weight HA without adding a full extra step. You mix 1-2 drops into whatever moisturiser you already use, so there's no layering, no pilling, and no sticky residue. It's also a smarter pick if you've been burned by high-percentage HA serums. Concentrations above roughly 1% create thick gels that can feel goopy on skin, and above 2% they can actually draw moisture out of skin in dry environments. What makes this hyaluronic acid booster different from other HA serums? Most HA serums rely on one or two molecular weights, which means they only hydrate at one depth. Pai's formulation uses three distinct molecular weights working simultaneously: high MW forms a moisture-locking film on the surface, medium MW hydrates the upper epidermis, and low MW penetrates to the deeper epidermal layers. Published research confirms multi-weight combinations produce synergistic hydration effects that single-weight formulations simply can't match. Does this booster contain any prebiotic ingredients and what do they do? Yes. It contains inulin, a prebiotic derived from chicory root that's included across the entire Pai Labs Booster range. Inulin feeds the beneficial bacteria on your skin's surface, supporting a healthy microbiome that helps maintain optimal barrier function and balanced skin pH.
