Hyaluronic Acid Booster Serum
A lightweight, budget-friendly hydrating serum formulated with 2% Hyaluronic Acid and Pro-Vitamin B5 (Panthenol) to deliver intense moisture, plump dehydrated skin, and leave your complexion feeling soft and refreshed without any sticky residue.
โจ Texture & Feel
Intense Hydration
2% Hyaluronic Acid binds up to 1000x its weight in water, drawing moisture deep into the skin for lasting plumpness.
Barrier Support
Pro-Vitamin B5 (Panthenol) helps strengthen the skin barrier and promotes wound healing for healthier skin.
Clean Formula
Free from fragrances, parabens, silicones, oils, and sulfates. Only 11 carefully selected ingredients.
Budget-Friendly
Professional-grade hydration at a fraction of the cost of luxury serums. Incredible value at just ยฃ3.50.
๐ก๏ธ Safety & Compatibility
Hyaluronic acid is naturally occurring in the body and topical application is considered completely safe during pregnancy and nursing.
Contains no oils, fatty acids, esters, or ferments that feed Malassezia yeast. Verified safe for fungal acne-prone skin.
Oil-free, lightweight formula with a comedogenic rating of 0. Will not clog pores or cause breakouts.
For optimal results, apply to slightly damp skin. HA draws moisture from its surroundings, so damp skin ensures it pulls water into the skin rather than from deeper layers.
๐ฌ Ingredient Breakdown
๐ง Sodium Hyaluronate 2% Proven
The salt form of hyaluronic acid, known for its exceptional water-binding capacity. It can hold up to 1000 times its weight in water, providing intense hydration to the skin's surface layers.
- Mechanism: Acts as a humectant, drawing water from the environment and deeper skin layers to hydrate the stratum corneum
- Benefit: Plumps skin, reduces appearance of fine lines, improves skin texture
- Research: Extensively studied with proven efficacy for skin hydration
โจ Panthenol (Pro-Vitamin B5) Proven
A powerful humectant that converts to pantothenic acid in the skin. Enhances hydration while supporting the skin's natural barrier function and promoting wound healing.
- Mechanism: Penetrates into the skin and converts to vitamin B5, stimulating cell regeneration
- Benefit: Moisturizes, soothes irritation, and accelerates skin repair
- Research: Well-documented anti-inflammatory and wound-healing properties
๐งด Propylene Glycol & Propanediol Supporting
Two gentle humectants that work synergistically to boost hydration. They help the formula spread smoothly and enhance penetration of other active ingredients.
- Propylene Glycol: Estimated ~6% concentration, draws moisture to skin
- Propanediol: Estimated ~4% concentration, plant-derived, softens and smooths
- Function: Both act as solvents and penetration enhancers
๐ Citric Acid pH Adjuster
An alpha hydroxy acid (AHA) derived from citrus fruits. In this formulation, it's used primarily as a pH adjuster rather than an active exfoliant, ensuring the serum remains effective and stable.
- Function: Adjusts and maintains optimal pH for ingredient efficacy
- Note: At this low concentration, provides minimal exfoliation
11 ingredients
Aqua (Water), Propylene Glycol, Propanediol, Sodium Hyaluronate, Citric Acid, 1,2-Hexanediol, Sodium Hydroxide, Phenoxyethanol, Butylene Glycol, Trisodium Ethylenediamine Disuccinate, Panthenol
๐ Where It Fits in Your Routine
Apply after cleansing and toning, before heavier serums and moisturizer. Works best on damp skin to maximize hydration benefits.
๐ How to Use
Cleanse Your Skin
Start with freshly cleansed skin. Pat dry but leave skin slightly damp for best results.
Apply 3-4 Drops
Dispense 3-4 drops onto your fingertips. A little goes a long way with this concentrated formula.
Gently Press Into Skin
Using gentle pressing motions, pat the serum into your face and neck. Avoid rubbing to prevent irritation.
Follow With Moisturizer
Seal in the hydration with a moisturizer containing occlusive ingredients to lock in the moisture and prevent evaporation.

โ Frequently Asked Questions
Yes, this serum is completely safe during pregnancy and breastfeeding. Hyaluronic acid is a naturally occurring substance in the body and topical application does not enter the bloodstream in significant amounts. The formula contains no retinoids, salicylic acid, hydroquinone, or other ingredients of concern during pregnancy.
Yes, this serum is verified fungal acne safe. The formula contains no oils, fatty acids, esters, polysorbates, or fermented ingredients that feed Malassezia yeast. It's an excellent hydrating option for those dealing with fungal acne or pityrosporum folliculitis.
Yes, hyaluronic acid is compatible with virtually all other skincare ingredients. Apply HA serum first to damp skin, then layer your retinol, vitamin C, or acids on top. HA can actually help buffer potentially irritating actives and provide hydration that counteracts dryness from exfoliating acids or retinoids.
This serum works well for all skin types but is particularly excellent for oily, combination, sensitive, and acne-prone skin due to its lightweight, oil-free formula. Dry skin types will benefit but should always follow with a moisturizer containing occlusive ingredients to seal in the hydration.
You'll notice immediate hydration and plumping effects after the first application. For lasting improvements in skin texture and barrier function, consistent use for 2-4 weeks is recommended. The panthenol component provides cumulative barrier-strengthening benefits over 6-8 weeks of regular use.
Apply after cleansing and toning, before heavier serums and moisturizer. The general rule is to apply products from thinnest to thickest consistency. Apply to slightly damp skin for best results, then follow with your treatment serums and seal everything with moisturizer (and sunscreen in the morning).
No, this serum has a comedogenic rating of 0 and will not clog pores. It's completely oil-free and contains no comedogenic ingredients. The formula is safe for acne-prone skin and those with congested pores.
The serum has a 12-month PAO (Period After Opening). With twice-daily use (3-4 drops each time), the 27ml bottle typically lasts 4-6 weeks. Store in a cool, dry place away from direct sunlight to maintain potency throughout its shelf life.
Verdict: Primark's Hyaluronic Acid Booster Serum delivers impressive hydration at an unbeatable price point. With a clean 11-ingredient formula, 2% hyaluronic acid, and supporting panthenol, it offers solid performance that rivals products costing 3-4 times more. While it lacks the multiple molecular weights of HA and ceramides found in premium alternatives, its fungal acne safety, pregnancy compatibility, and lightweight texture make it an excellent entry point for hyaluronic acid beginners or a budget-friendly staple for seasoned skincare enthusiasts. The main drawbacks are the small bottle size and in-store-only availability. Overall, exceptional value for money.
