Compare Products: Glass Skin Refining Serum vs SuperSolutions 20% Niacinamide Serum
Ingredient Analysis
Peach & Lily Glass Skin Refining Serum is a hydration-focused serum stacked with multiple hyaluronic acid forms and skin-calming centella extracts. The Inkey List SuperSolutions 20% Niacinamide Serum leads with niacinamide and adds zinc for sebum and pore control. The better pick depends on whether your goal is deep hydration or oil and pore management.
Peach & Lily Glass Skin Refining Serum uses three forms of hyaluronic acid plus saccharide isomerate, covering surface and deeper skin layers. The Inkey List SuperSolutions 20% Niacinamide Serum relies mainly on glycerin for moisture.
Zinc PCA directly regulates sebum production. Peach & Lily Glass Skin Refining Serum has no comparable sebum-control ingredient.
Madecassoside, asiaticoside, and beta-glucan form a strong soothing stack. The Inkey List SuperSolutions 20% Niacinamide Serum has no dedicated calming actives.
Adenosine and acetyl octapeptide-3 target firmness and expression lines. The Inkey List SuperSolutions 20% Niacinamide Serum lacks dedicated anti-aging actives.
Peach & Lily Glass Skin Refining Serum uses ethylhexylglycerin and caprylyl glycol as preservatives, which are gentler. The Inkey List SuperSolutions 20% Niacinamide Serum combines phenoxyethanol, benzyl alcohol, and dehydroacetic acid, a heavier preservative system.
- •Niacinamide concentration is undisclosed in both products. Efficacy varies significantly between 2% and 10%.
- •Peach & Lily Glass Skin Refining Serum lists niacinamide fourth, suggesting a moderate dose. The Inkey List SuperSolutions 20% Niacinamide Serum lists it second, hinting at a higher dose, but this is inference only.
- •Acetyl octapeptide-3 in Peach & Lily Glass Skin Refining Serum appears late in the list, so its concentration may be too low to deliver noticeable results.
- •Exact centella compound percentages in Peach & Lily Glass Skin Refining Serum are unknown; clinical centella studies typically use 1% or higher.
- •Zinc PCA position in The Inkey List SuperSolutions 20% Niacinamide Serum is near the end, so its sebum-control effect may be limited at the actual concentration used.
- •Neither formula discloses pH, which affects niacinamide and centella ingredient stability.

User Feedback Patterns
Users consistently report improved hydration and a plumper, more luminous appearance. Many describe the 'glass skin' effect as real.
Eczema-prone and reactive skin users frequently report no irritation. Popular first serum for those new to actives.
Lightweight gel texture absorbs quickly. Some note a slight initial tack that disappears once fully absorbed. Layers well.
Multiple users report gradual fading of acne scars and improved evenness over weeks of use.
High repurchase rate in reviews. Users describe it as a staple they consistently return to.
Users with very oily skin consistently report this as one of the most effective oil-control products they have tried. Many note all-day mattifying effect.
Despite the 20% concentration, most users report no irritation. However, patch testing is frequently mentioned as important for first-time users.
Users who found The Ordinary's 10% niacinamide too weak or pilling-prone often prefer this. The gel texture absorbs cleanly.
Some users report a white film if they apply too much. The brand addresses this: use less product and follow immediately with moisturizer.
