1. 

   1. The INKEY List Niacinamide Serum

   Niacinamide 10% · zinc none · shares 10 of 25 · $13.00 for 1 oz ($13.00/oz)

   How it feels: A light serum that leaves skin feeling smooth and hydrated, not tight.

   Best for the closest formula. Same 10% niacinamide and, like Paula's Choice, no zinc. It shares more of the booster's ingredients than any other serum here, including phospholipids, allantoin and panthenol, and adds hyaluronic acid and squalane.

   Trade-off: No vitamin C or licorice. It costs about the same as the other 1 oz serums here, not the cheapest.

   2. Cos De BAHA Niacinamide 10% Serum

   Niacinamide 10% · zinc 1% · shares 6 of 25 · $12.99 for 1 oz ($12.99/oz)

   How it feels: A slightly thick serum that absorbs well but can stay a little sticky, so give it a minute before the next layer. No scent.

   Best for licorice and the soothing extras. Same 10% niacinamide, plus four of the original's soothing extras: hyaluronic acid, allantoin, licorice (dipotassium glycyrrhizate) and panthenol. It is the only one here with licorice. Its base is aloe instead of water.

   Trade-off: It adds 1% zinc, has no vitamin C, and is thicker and a bit sticky, not watery like the booster.

   3. Good Molecules Niacinamide Serum

   Niacinamide 10% · zinc none · shares 5 of 25 · $5.97 for 1 oz ($5.97/oz)

   How it feels: Very light and quick to sink in. It is not tacky or greasy, has no scent, and layers well with a dewy look.

   Best for the lowest price with the same light feel. Same 10% niacinamide, no zinc, and a light, fast-sinking texture closest to the booster's. It costs a fraction of the price per ounce.

   Trade-off: It is a simple formula: none of the booster's vitamin C, licorice, allantoin or panthenol.

   4. The Ordinary Niacinamide 10% + Zinc 1%

   Niacinamide 10% · zinc 1% · shares 4 of 25 · $6.00 for 1 oz ($6.00/oz)

   How it feels: A thick, clear serum that dries a little tacky. It can pill under some moisturizers and sunscreens, so use 2 to 3 drops and let it dry first.

   Best for blemish-prone, oily skin. Same 10% niacinamide plus 1% zinc; The Ordinary sells it for blemish-prone skin. It is the one most dupe lists name.

   Trade-off: Much thicker than the booster and can pill. It shares little else with Paula's Choice: no vitamin C, licorice, allantoin or panthenol.

   5. Naturium Niacinamide Serum 12% Plus Zinc 2%

   Niacinamide 12% · zinc 2% · shares 7 of 25 · $13.59 for 1 oz ($13.59/oz)

   How it feels: Lightweight and fast to absorb, with no residue or scent. It layers under moisturizer and makeup.

   Best for a stronger dose. 12% niacinamide and 2% zinc, more of both than the others, plus hyaluronic acid. It feels light, like the booster.

   Trade-off: Not a like-for-like swap: the higher dose can make sensitive skin flush or tingle, and it has none of the booster's vitamin C or licorice.
