MEDIX 5.5 - 3% Hyaluronic Acid - 50ml

Overview

The Medix 5.5 3% Hyaluronic Acid serum is a high-concentration hydration booster designed to deliver intense moisture, plump the skin, smooth fine lines, and support the skin barrier. It is formulated with 3% hyaluronic acid at multiple molecular weights (so it can penetrate and hydrate various layers of the skin) and is enriched with soothing/botanical-support ingredients to enhance its effect.
According to product descriptions, it is designed for both face and body use (though often used on face), and suitable for dry, dehydrated, or ageing skin needing extra moisture and plumping. 

🔬 Key Technologies & Ingredients

Here are the standout features of this formula:

• 3% Hyaluronic Acid (HA): A relatively high percentage for HA serum; the formula uses three molecular weights of HA (low, medium, high) to provide “multi-layer” hydration — surface, mid-epidermis, deeper layers.

• pH Optimised / Skin Barrier Friendly: The brand and independent breakdown note that the product is formulated to pH around 5.5 (hence the brand name). This supports a healthier skin barrier. 

• Supportive Botanical & Soothing Actives: Includes Aloe vera, Kelp, Centella Asiatica, Green Tea extract, Cucumber extract, etc., which help calm, soothe and support barrier repair. 

• Fragrance-free / Minimal Irritant Formulation: According to sources, the product is free of added fragrance and essential oils.

🌟 Key Benefits

Using the Medix 5.5 3% Hyaluronic Acid serum offers several benefits:

• Deep hydration & plumping – The high concentration HA draws water into the skin, increasing moisture content and making skin feel plumper and more supple.

• Smoothing fine lines – With skin better hydrated and supported, fine lines (especially those caused by dehydration) appear less noticeable.

• Improving skin texture – Hydrated skin tends to have smoother texture and better bounce; the supporting botanical actives help mitigate roughness or flaky patches.

• Supporting the skin barrier – With its pH-friendly formulation and soothing ingredients, the serum helps strengthen the barrier (important for all skin types, especially sensitive or compromised).

• Versatile use – Described as a booster that can be used on face and body, or mixed in or layered into your routine to boost hydration. 

🧴 How to Use

To get the best results from this serum:

1. After cleansing (and toning, if you use one), apply a moderate amount of the Medix 5.5 3% Hyaluronic Acid serum to clean, slightly damp skin.

2. Evenly spread across the face (and neck if desired). Because the product is quite hydrating, applying to slightly damp skin helps the humectant HA draw in moisture rather than draw it from skin.

3. Follow with your usual serum/cream. Given this is a hydrating booster, after it has absorbed, you can apply your regular serum or moisturizer to “lock in” the hydration. Some sources suggest either following it with a body cream (if using on body) or applying a moisturizer afterwards. 

4. Use daily, morning or night (or both) depending on your routine and skin needs. If using in the morning, follow with sunscreen.

5. If combining with actives (exfoliants, retinoids, etc.), this HA serum fits well as a soothing, hydrating step to offset potential dryness.

👩🔬 Skin Types & Concerns It Suits

• Best for: Normal, combination, dry, dehydrated, or ageing skin types that need heightened hydration and plumping.

• Also suitable for: Sensitive skin, because of its soothing and fragrance-free nature — though always patch testing is wise.

• Possible caution for: Oily skin that prefers lighter textures — though HA tends to be well tolerated by oily skin if formulated lightly; just ensure the rest of your routine supports your skin type.

• Concerns addressed: Dehydration, fine lines, dullness, rough texture, skin barrier support.

⚠️ What to Note / Cautions

• While HA itself is very well-tolerated, dehydration-type fine lines may reduce, but deeper wrinkles/imprints need multiple actives and time.

• Although the formula is “booster/hydrator” style, layering it with heavy occlusives may alter its “feel” or finish.

• If using under strong actives (like retinoids or exfoliants) make sure the rest of your routine supports barrier recovery (e.g., moisturiser, SPF).

• Because HA is humectant in nature, if skin is extremely dry and there is low ambient humidity, sometimes humectants can draw moisture out of skin rather than in; thus ensure you follow with a moisturizer or occlusive layer if needed in very dry climates.

• Always check for exact ingredient list (formulas can be updated); the version you purchase may differ slightly.

• Ensure you buy from reliable sellers to guarantee authenticity.
