Which Hyaluronic Acid & Niacinamide Serum Should You Buy? A Simple Guide

Choosing a serum can be overwhelming when every product promises glowing, hydrated, and healthier skin. If your goal is deep hydration, barrier repair, plumper texture, and balanced skin, serums with Hyaluronic Acid and Niacinamide are some of the best foundational options. Below is a guide to help you understand which serum suits your needs based on your skin goals.

1. Phimedy Absolute Glow Serum

Best For: Brightening, hydration, even tone, daily use

What It Is:

Phimedy Absolute Glow Serum is a multi-action serum that combines Hyaluronic Acid for deep hydration and potent brightening ingredients like Vitamin C and Niacinamide to support even tone and radiance.

Why You Should Buy It:

✔ Deep Hydration: Hyaluronic Acid helps attract and lock in moisture, giving skin a plump, soft feel.

✔ Daily-Friendly: Gentle, lightweight formula that works well for most skin types, including sensitive skin.
✔ Balanced Routine Fit: Great for everyday use—morning and night.

Ideal If You Want:

A hydration + glow + barrier support serum that does more than just moisturise—one that also improves dullness and dull patchiness.

2. Dermatica HA Pure Serum
