EQQUALBERRY Vitamin Illuminating Serum dupes: 3 serums with the closest formula
We compared EQQUALBERRY Vitamin Illuminating Serum's full ingredient list with every serum in the DemythSkin database, weighting the ingredients that do the work (Tranexamic Acid, Niacinamide and Betaine) far above fillers. These are the closest matches, each with its own efficacy and safety score.
Match is how much of EQQUALBERRY Vitamin Illuminating Serum's weighted formula a product shares. Scores are each product's own, so a dupe can match closely and still score differently.
Prices are the lowest retailer price in our records; a dash means we don't have one. We earn a commission if you buy through a "Find on Amazon" link. It never affects scores or matches.

How we find a dupe
01
Same product type
Serums are compared with serums, from the products we've scored.
02
Actives count most
S and A-grade actives weigh up to 30 times more than water, glycerin or thickeners. A dupe must share at least one key active.
03
30% match or more
Below that it isn't a dupe. Same brand and renamed versions of the original are left out.
A label lists ingredients, not amounts. Two products can share every ingredient at different strengths, so a high match means a similar formula, not a guaranteed identical result.
What is the best dupe for EQQUALBERRY Vitamin Illuminating Serum?
On formula, COSRX 5 PDRN Collagen Intense Vitalizing Serum: a 41% match, sharing Niacinamide, Betaine, Panthenol and Tocopherol. It scores 4.1 for efficacy and 4.5 for safety on DemythSkin's ingredient analysis. Medicube PDRN Pink One Day Serum is next at 30%.
Is COSRX 5 PDRN Collagen Intense Vitalizing Serum the same as EQQUALBERRY Vitamin Illuminating Serum?
Their ingredient lists overlap closely (41% by our weighted match), but labels list ingredients, not amounts. Two products can share ingredients at different strengths, so treat it as a close formula, not a confirmed copy.
What is a cheaper alternative to EQQUALBERRY Vitamin Illuminating Serum?
Of the dupes we have a price for, the lowest is COSRX 5 PDRN Collagen Intense Vitalizing Serum at $14 (a 41% formula match), against $21.99 for EQQUALBERRY Vitamin Illuminating Serum. Prices are the lowest retailer price in our records and change often.
How do you calculate the match percentage?
We compare full ingredient lists of the same product type, giving proven actives up to 30 times more weight than water, glycerin or thickeners. A dupe must share at least one key active and reach a 30% match; products from the same brand are left out.
