Lightweight face moisturizer for sensitive skin
About
What it is.
Hyaluronic Acid Serum is a water-light hydrating serum from Good Molecules, formulated with hyaluronic acid in two molecular weights so it can reach both surface and deeper skin layers. It sits in the hydrating-serum subtype of the brand's skincare line, positioned as a layering step rather than a standalone moisturizer, applied before oils and creams.
It's built for dehydration and loss of firmness rather than for treating specific conditions like acne or pigmentation, and it's formulated to suit all skin types, including sensitive skin, since it's fragrance-free. Good Molecules markets it for daily morning-and-night use, meant to slot into an existing routine alongside other actives rather than replace them.
The verdict
This lightweight, fast-absorbing serum hydrates effectively without tackiness, but requires a heavier moisturizer on top to prevent moisture loss—best suited to those layering it into an existing routine rather than seeking a standalone cream.

Frequently asked
What buyers want to know.
Does this serum feel sticky or greasy on skin?
Reviewers say no. The texture is watery and absorbs quickly without leaving residue, tackiness, or a greasy feel.
Can I use this serum on its own, or do I need to layer it with other products?
Reviewers note this is not a standalone moisturizer and works best layered with a heavier cream or oil on top. In dry climates especially, pairing it with a richer moisturizer prevents the serum from pulling moisture out of skin.
Who is this serum best for?
Reviewers say it suits anyone with dry, dehydrated, or combination skin who wants a simple hydration boost to add to an existing routine. It's not the right fit for those seeking a richer, standalone moisturizer or a serum with active ingredients beyond basic hydration.
Does it deliver visible results?
Reviewers report noticeable hydration and plumpness across various skin types, and say it layers well with other products for daily morning and night use.
What makes the ingredient list stand out?
Reviewers describe it as simple and transparent, with no extra actives—just straightforward hydration with no added complexity.
