Hyaluronic acid (HA) is a skincare superstar loved for its unparalleled hydration and plumping effects. But should you buy a ready-made serum or DIY it using pure HA powder? I decided to compare two crowd favorites — The Skin Science Company’s high molecular weight HA powder and The Ordinary’s Hyaluronic Acid 2% + B5 Serum — to see which suits your skin and routine best.
Product Overview
The Skin Science Company Hyaluronic Acid Powder
Pure, high molecular weight HA powder (0.8–1.3 million Daltons) Intended for DIY formulation — you mix it yourself with distilled water and preservative No additives, fragrance, or fillers — complete control over concentration and freshness Requires basic measuring tools and some patience during mixing/hydration phase
The Ordinary Hyaluronic Acid 2% + B5 Serum
Ready-to-use, water-based serum containing 2% HA with a mix of molecular weights Enhanced with Vitamin B5 for added skin barrier support and repair Fragrance-free, lightweight, fast-absorbing formula Affordable and widely available, ideal for quick, no-fuss use
Texture & Absorption
SSC Powder (DIY Serum): When properly mixed, the DIY serum has a slightly thicker, gel-like texture compared to commercial serums. It forms a smooth hydrating film on the skin, with no tackiness or residue. Absorption is good but slightly slower due to higher molecular weight HA sitting mostly on the surface to lock in moisture.
The Ordinary Serum: Lightweight, watery, and absorbs almost instantly. The blend of low and high molecular weight HA allows for multi-layered hydration — surface plumping and some penetration into the upper skin layers. It feels almost weightless, perfect for layering.
Hydration & Skin Feel After Use
Both products significantly boost skin hydration. The DIY SSC serum feels more occlusive, giving a subtle “plump” and protective layer that lasts longer on my dry skin.
The Ordinary’s serum gives a fresh, immediate boost and works well under makeup and moisturizers without feeling heavy.
Convenience & Practicality
DIYing the SSC serum requires time — mixing, waiting 2-4 hours for full hydration, and adding preservatives to ensure safety. It’s ideal if you love customization and control, or want to avoid preservatives/fillers.
The Ordinary’s serum is plug-and-play: open and apply. No mixing, no prep. Perfect for busy people or skincare beginners.
Cost & Value
Buying SSC HA powder in bulk is cost-effective for making multiple batches and adjusting concentrations. It’s economical if you plan to DIY regularly and have the tools.
The Ordinary serum is competitively priced for a ready-to-go product but can become pricier over time compared to DIY bulk powder.
Suitability for Skin Types
Both are suitable for all skin types, including sensitive and acne-prone skin.
The SSC powder-based serum can be tailored to lower concentrations if your skin is reactive. The Ordinary’s serum formulation has added Vitamin B5, beneficial for skin repair and barrier support.
Final Verdict: Which Should You Choose?
If you love DIY and want total ingredient control, go for The Skin Science Company’s powder. It’s a rewarding project and allows you to make exactly what your skin needs.
If you want something easy, effective, and ready to apply, The Ordinary’s serum is a fantastic budget-friendly option trusted by many.
How I Use Both in My Routine
I actually rotate both. For quick mornings or travel, I use The Ordinary serum. When I have time, I mix my own SSC serum at a slightly higher concentration for overnight hydration and skin barrier support.
