Amplified Glow Brightening Vitamin C Serum Review

What this product is

The Amplified Glow™ Brightening Vitamin C Serum is a 60 mL leave-on facial serum. Amplified Glow names sodium ascorbyl phosphate as the vitamin C form, alongside ferulic acid, hyaluronic acid, vitamin E, coconut oil, jojoba oil and riboflavin.

It is the only product in the Amplified Glow catalogue built around vitamin C rather than peptides, which makes it the natural point of comparison for anyone deciding between an antioxidant serum and a copper peptide serum. We work through that decision on the vitamin C versus copper peptide comparison page.

Formula and ingredient context

Naming sodium ascorbyl phosphate rather than writing "Vitamin C" is a genuinely informative disclosure, and it is worth understanding why.

"Vitamin C" in cosmetics is not one ingredient. Ascorbic acid is the unmodified form. Sodium ascorbyl phosphate is a salt of a phosphorylated derivative, used in formulation partly because it is more stable in water-based products than ascorbic acid. Those are different ingredients with different formulation constraints, and a product page that names the specific one is telling you something a product page that says "Vitamin C" is not. Our sodium ascorbyl phosphate page goes into what the ingredient-level evidence can and cannot establish.

Amplified Glow also discloses ferulic acid and vitamin E, both of which are commonly formulated alongside vitamin C derivatives. Presence is disclosed; concentrations are not, for any of the three.

One further gap is worth flagging plainly. The page discloses no fragrance statement at all, while listing botanical oils that carry scent. An absent fragrance claim is not a fragrance-free claim, and we do not treat it as one.

Routine fit

Amplified Glow directs users to apply a few drops to clean skin each morning, massage into the face and neck until absorbed, then follow with moisturizer and sunscreen. That is a once-daily morning position, which differs from the twice-daily direction the brand gives for both copper peptide serums.

Because it occupies the morning serum slot and the peptide serums are directed for morning and evening, the two are not mutually exclusive on the brand's own instructions. Amplified Glow does not publish combining guidance, and we have not invented any — see vitamin C and copper peptide routine considerations for what is actually established and what is not.

Price and value context

Listed at $21.00, reduced from $25.00. At 60 mL that is $35.00 per 100 mL at the sale price — the lowest of any Amplified Glow facial serum, and 30% less per millilitre than the Copper Peptide Renewal Serum in the same 60 mL size.

That gap is unsurprising given the formulas differ substantially, and it is not evidence that one is better value in any sense beyond volume for money. Price per millilitre compares volume, not formulation.

Safety and patch-test information

This product page carries the general Amplified Glow cosmetic disclaimer but, unlike most of the range, no product-specific warnings and no patch-test recommendation.

We would suggest patch testing anyway. Amplified Glow recommends it for its peptide serums, creams, cleanser and muscle rub, and there is no obvious reason the advice would not apply equally here. How to patch test a new cosmetic product sets out a method.

Evidence notes

Size, price, the sodium ascorbyl phosphate disclosure, hero ingredients and directions come from the Amplified Glow product page and shop listing, checked on the date shown at the top of this page.

The absence of a fragrance statement, of patch-test guidance and of product-specific warnings was confirmed by reading the full product page, not inferred.
