Norvell Pre Tan DHA Boost vs Tan Inc. Fantasy Skin Drops

Two DHA boosters, two dosing systems

Norvell Pre Tan DHA Boost and Tan Inc. Fantasy Skin DHA Boost both let you raise the color depth of a sunless tan, but they are not interchangeable drop-for-drop. The supplied records show different package sizes, different concentration language, and different mixing directions. That makes this a comparison of dosing systems, not a simple strength contest.

Use the manufacturer's mixing direction on each label as your starting point. If a product record does not supply a full preparation or operating procedure, treat that as a gap to resolve with the manufacturer before you change a client's formula.

What each bottle actually contains

• Tan Inc. Fantasy Skin DHA Boost 1 oz.: 1 oz. bottle of 40% concentrated DHA drops, fragrance-free, formulated for sunless use. The small bottle and stated 40% concentration tell you this is a highly concentrated additive, so measuring drops matters more than volume.

  

• Norvell Pre Tan DHA Boost 2 oz.: 2 fl. oz. / 59 mL bottle; the directions say to add 1 dropper full to any Norvell spray tan solution to increase tan 1–2 levels. The dropper-based direction gives you a repeatable unit of measure and a stated effect range for Norvell solutions.

  

Dosing and effect: drops versus a dropper full

The biggest practical difference is how each brand asks you to measure. Tan Inc. gives a drop count tied to a specific volume of solution; Norvell gives a dropper full tied to a level increase. Neither is automatically 'stronger' without knowing your starting solution.

• Tan Inc. Fantasy Skin DHA Boost: Directions: mix 4–6 drops with 2 ounces of solution to raise sunless potency 1%. That is a volume-based ratio you can scale, but the record does not state a maximum number of increments per batch.
• Norvell Pre Tan DHA Boost: Add 1 dropper full to any Norvell spray tan solution to increase tan 1–2 levels. The record does not give a milliliter equivalent for one dropper full, so measure with the supplied dropper rather than guessing.

Concentration and compatibility caveats

Tan Inc. states 40% concentrated DHA and describes the product as recommended for those who crave a darker DHA sunless tan. Norvell describes its booster as DHA combined with erythrulose to help develop a longer-lasting tan and increase moisturization. Those are different formulation claims from each manufacturer, and neither record supplies a full ingredient list.

Norvell's directions specifically say to add the booster to any Norvell spray tan solution. The supplied record does not confirm compatibility with other brands' solutions. Tan Inc.'s directions refer to mixing with 2 ounces of solution but do not name a brand restriction. If you use a non-Norvell base with the Norvell booster, confirm compatibility with Norvell first rather than assuming it.

Catalog details that affect the buying decision

• Tan Inc. Fantasy Skin DHA Boost 1 oz.: Catalog price USD 17.76, compared with a catalog comparison price of USD 26.50. The lower entry price makes the 1 oz. Tan Inc. bottle a smaller commitment if you are testing a darker result.
• Norvell Pre Tan DHA Boost 2 oz.: Catalog price USD 38.65, compared with a catalog comparison price of USD 52.94. The higher price buys a larger 2 fl. oz. bottle and a dropper-based dosing method.

How to choose between them

• You already run Norvell solutions: Norvell Pre Tan DHA Boost is the straighter fit because its directions are written for Norvell spray tan solutions and give a 1–2 level target.
• You want drop-level control in small batches: Tan Inc. Fantasy Skin DHA Boost gives a 4–6 drops per 2 ounces ratio, which suits measured trials. Start at the low end of the supplied range before increasing.
• You need fragrance-free: Tan Inc. explicitly lists fragrance-free. The Norvell record does not state fragrance status, so do not assume either way.
• You want the longest track record in the record: Neither record supplies independent test data. Judge by your own patch test and the manufacturer's directions, not by marketing language.

What the records do not tell you

Neither supplied record includes a full ingredient list, a maximum boost limit, or a patch-test protocol. The Norvell record does not state a concentration percentage, and the Tan Inc. record does not state an expected level increase beyond the 1% potency raise per 4–6 drops in 2 ounces. If you need those details for client safety or insurance documentation, request them from the manufacturer before mixing.

Both products are sold as new spray tanning equipment with no tax in most states, according to the store context. That is purchase information, not a performance claim. For either booster, the reliable path is to follow the label ratio, test on a small batch, and keep notes on the base solution you used.
