Compare Products: Glass Skin Refining Serum vs Niacinamide 10% + Zinc 1% Serum
Ingredient Analysis
Peach & Lily Glass Skin Refining Serum is a richer, multi-layered hydrating serum with three forms of hyaluronic acid and calming centella actives. The Ordinary Niacinamide 10% + Zinc 1% Serum is a leaner, targeted niacinamide-and-zinc formula focused on pore refinement and oil control. Neither is universally better; the right pick depends on your skin concern.
Peach & Lily Glass Skin Refining Serum contains three distinct hyaluronic acid forms plus saccharide isomerate and beta-glucan. The Ordinary Niacinamide 10% + Zinc 1% Serum offers minimal humectancy beyond pentylene glycol.
The Ordinary Niacinamide 10% + Zinc 1% Serum pairs niacinamide with zinc PCA, a combination specifically aimed at sebum regulation. Peach & Lily Glass Skin Refining Serum has niacinamide but no zinc or sebum-targeting co-active.
Madecassoside, asiaticoside, beta-glucan, and adenosine in Peach & Lily Glass Skin Refining Serum form a strong anti-irritation and barrier-repair stack. The Ordinary Niacinamide 10% + Zinc 1% Serum has nothing comparable.
Adenosine and acetyl octapeptide-3 address fine lines directly. The Ordinary Niacinamide 10% + Zinc 1% Serum contains no dedicated anti-aging ingredients.
The Ordinary Niacinamide 10% + Zinc 1% Serum has far fewer ingredients, reducing the chance of a reaction. Peach & Lily Glass Skin Refining Serum's phytic acid and length may not suit very reactive skin.
