If you have dry or dehydrated skin, you’ll know the desperation of searching for a serum that truly delivers. The Geek & Gorgeous HA 5 Rich is an affordable, no-nonsense hydrating serum that punches far above its price point, leaving skin quenched, plumped, and comforted.
What is it?
A hydrating serum for dry and dehydrated skin.
What Do I Think?
At its heart is a blend of five types of hyaluronic acid, which work synergistically to attract and hold onto moisture at every layer of the skin. Then there’s Tremella Fuciformis, a mushroom extract often dubbed nature’s hyaluronic acid for its superb water-binding capabilities, and Panthenol, a soothing, dependable ingredient that helps fortify the skin barrier.
For best results, I like to apply this to slightly damp skin – this small tweak supercharges hydration, giving the serum something to grab onto. Layered over the brand’s Liquid Hydration Toner (read my review here), it’s a winter savior for parched, tight skin like mine.
Texture-wise, it’s an utter delight. Where so many hydrating serums stumble with that telltale tackiness, this one is silky, sinks in seamlessly, and layers beautifully under other products, no pilling or stickiness in sight. It’s light enough for summer yet nourishing enough to combat harsh winter conditions, making it a versatile staple.
While I’d argue it’s suitable for almost anyone looking to boost hydration, it truly shines for normal to dry skin types. If you’re on the oily side, the brand thoughtfully offers a lighter alternative.

Would I recommend?
In short, Geek & Gorgeous HA 5 Rich is everything a good hydrating serum should be: elegant, effective, and a treat to use. At this price, it feels almost too good to be true – but I’m not complaining.
Brands Product Description
5 forms of Hyaluronic Acid in varying molecular weight and structure join forces in this silky & rich formula to hydrate, soften and plump the skin. Hyaluronic Acid is a natural moisturizing factor (NMF) that can bind up to 1000 times its own weight in water. This formula focuses on ultra-moisturizing high molecular weight versions for ample surface hydration as well as on medium molecular weight versions, whose strong point is to strengthen the skin barrier and to reinforce the skin’s natural defense & healing mechanisms.
Key Ingredients
- Sodium Hyaluronate Crosspolymer – A new generation, cross-linked Hyaluronic Acid, whose water binding ability is several times greater than the already amazing water-binding ability of Hyaluronic Acid. Also offers longer-term moisturizing benefits.
- Sodium Hyaluronate – The most common, salt-form of Hyaluronic Acid that can be found in larger and smaller molecular weight in the formula.
- Tremella Fuciformis (Mushroom) Extract – The extract of silver ear mushroom known for its amazing water-binding abilities. It contains sugar constituents including Glucuronic Acid, one of the building blocks of Hyaluronic Acid. It also cosmetically elegant, non-sticky and has additional antioxidant benefits.
- Hydrolyzed Hyaluronic Acid – A smaller molecular weight version of Hyaluronic Acid that is known for its ability to reinforce the skin’s natural defense & healing mechanisms.
- Panthenol – A classic skincare ingredient that is a reliable soothing, moisturizing and skin-protecting agent.

How I Use It
I use this in my morning and evening routine, after using a hydrating mist or toner and before my other serums.
