Wellage vs. Round Lab Birch Serum
An eight-weight hyaluronic acid blend with a real Olive Young placement against a more botanically-diverse birch-and-vitamin-C formula, at a real price gap.

Both are fragrance-free hydration serums, but they take different formula strategies: hyaluronic-acid-weight variety versus a broader mix of botanical and active ingredients.
Why compare these two specifically
Both are fragrance-free hydration-first serums with real award or product-family pedigree behind them, but Wellage leans on hyaluronic-acid weight variety while Round Lab spreads its formula across several different ingredient categories.
Price per milliliter
Wellage runs $0.24 per milliliter ($24.00 for 100mL). Round Lab runs $0.40 per milliliter ($20.00 for 50mL). Wellage is meaningfully cheaper per mL, in a bottle twice the size.
HA-weight strategy vs. multi-category formula
Wellage uses eight types of hyaluronic acid alongside panthenol and a supporting PDRN inclusion, a strategy built on molecular-weight variety within one ingredient category. Round Lab spreads across categories instead: birch sap, hyaluronic acid, pure ascorbic acid for brightening, beta-glucan, and licorice root extract, a broader but less HA-weight-diverse formula.
Only one has a real, current award record
Wellage placed #3 in Olive Young's 2025 Essence/Serum category, a genuine domestic bestseller. Round Lab has no comparable award data, though it shares its birch-sap formula family with Round Lab's well-reviewed sunscreen line.
Our take
If pure hydration depth and a lower price matter most, Wellage's HA-weight variety and genuine award record make it the stronger, better-value pick. If you want brightening vitamin C and soothing botanicals bundled into the same step, Round Lab's broader formula justifies its higher per-mL price for that added functionality.
Wellage Real Hyaluronic Blue 100 Ampoule: $0.24/mL. Eight types of hyaluronic acid plus PDRN, a genuine Olive Young #3 placement, the better per-mL value.
Round Lab Birch Juice Moisturizing Serum: $0.40/mL. A broader formula combining birch sap, real ascorbic acid, beta-glucan, and licorice root, hydration plus brightening plus soothing in one step.
