The best beauty dupes under $20

Every pair here has a dupe that costs less than $20 and replaces a product costing at least twice that. The list is ordered by how much you keep per ounce, not by how loud the saving sounds: a $12 dupe of a $30 original beats a $19 dupe of a $45 one only if the sizes agree.

What are the best beauty dupes under $20?

NIVEA Creme Moisturizing Cream, about $10 ($0.74 / fl oz), against the $200 La Mer Crème de la Mer Moisturizing Cream — 99% less. Both are built on a mineral oil, petrolatum and glycerin base, which does most of the moisturizing. NIVEA lacks the kelp ferment and has a stronger scent. The price difference is more than 250× per ml.

Ranked by saving against the original — per ounce where both sizes are given, by price otherwise. Dupes priced $20 or more are excluded even when the saving is larger. Prices checked 23 September 2026.

    What matches

    Same main active (lactic acid) at a disclosed 10%.

    Key ingredients
    Original · K18K18Peptide™
    Dupe · COSRXTripeptide-132 HCl, Biotin, Soluble collagen, Hydrolyzed hyaluronic acid

    What matches

    Both rebuild broken keratin bonds with a low-molecular-weight peptide — K18Peptide in one, Tripeptide-132 in the other — and both are aimed at bleach, colour and heat damage.

    What the dupe does worse

    This one is rinsed out after a few minutes instead of left in, and it is silicone-and-oil heavy, so fine hair can be left with a slight film K18 never leaves.

  5. 5. wet n wild MegaLast Matte Lip Color – Stoplight Red for MAC Cosmetics Retro Matte Lipstick – Ruby Woo

    $3 against $24, 89% less ($25.77 / oz versus $226.80 / oz).

    What matches

    Same cool-toned blue red in a flat, high-pigment matte that photographs the way Ruby Woo does.

    What the dupe does worse

    Softer bullet and a semi-matte set, so it feels less drying but transfers more and needs a liner to hold its edge.

  6. 6. Makeup Revolution Skin Silk Serum Foundation for Giorgio Armani Beauty Luminous Silk Foundation

    $11 against $69, 84% less.

    What each one costs

    Giorgio Armani Beauty$68.02 / fl oz

    What matches

    Same serum-fluid texture and the same satin, skin-like finish that Luminous Silk is bought for, in a comparable medium coverage.

    What the dupe does worse

    Less shade depth at the extremes of the range and a shorter wear time on oily skin, around eight hours before it needs powder.

  7. 7. OGX Renewing + Argan Oil of Morocco Penetrating Oil for Moroccanoil Moroccanoil Treatment

    $8 against $48, 83% less ($2.37 / fl oz versus $14.20 / fl oz). Both list Argan oil.

    What matches

    Same argan-and-silicone base, same use on damp mid-lengths before drying, and the same shine without weight on fine hair.

    What the dupe does worse

    Thinner texture and a sweeter fragrance, and it runs out faster because people over-pour it.

  8. 8. e.l.f. Cosmetics Wow Brow for Benefit Cosmetics Gimme Brow+ Volumizing Fiber Gel

    $6 against $26, 80% less ($48.60 / oz versus $245.70 / oz).

    What the dupe does worse

    What matches

    Similar bouncy texture and a dewy finish, in the same jar size.

    What the dupe does worse

    It's lighter, so very dry skin may need an oil on top. Fragrance-free.

  11. 11. NYX Professional Makeup Epic Ink Liner for Stila Stay All Day Waterproof Liquid Eyeliner

    Key ingredients
    Original · StilaNot disclosed
    Dupe · NYX Professional MakeupNot disclosed

    What matches

    Brush tip instead of felt, so it's more flexible for thin-to-thick wings and needs a steadier hand. Just as black and just as waterproof, with twice the product for under half the price.

  12. 12. Tree Hut Coco Colada Whipped Body Butter for Sol de Janeiro Brazilian Bum Bum Cream

    $10 against $48, 79% less. Both list Coconut oil.

    Dupe · Tree Hut240 g
    Key ingredients
    Original · Sol de JaneiroCupuaçu butter, Coconut oil, Açaí
    Dupe · Tree HutShea butter, Coconut oil

    What matches

    Same coconut-and-vanilla gourmand scent trail and the same whipped, fast-absorbing body cream texture.

    What the dupe does worse

    No guaraná caffeine and no cupuaçu butter, so it moisturizes without the firming claim, and the scent sits closer to the skin.
