What are the Fizzing Lemon Cubes — are they a skincare product?

The Fizzing Lemon Cubes are a beverage experience, not skincare. They are luxury drink enhancers included to add a lifestyle dimension to the gift. Recipients enjoy them as a fizzy drink addition completely separately from their skincare routine. The skincare in this set is the Brightening Boost Vitamin C Power System.

Does vitamin C serum turn orange, and does this one do the same?

Liquid vitamin C serums turn yellow, then orange, then brown as L-Ascorbic Acid oxidizes on contact with air and light. An orange serum has lost meaningful potency. Because Exponent's vitamin C remains in dry powder form until activation, the oxidation clock only starts when you mix your single dose — no pre-use degradation, no orange discoloration.

Is this a good gift for someone who has never used vitamin C before?

Yes. Brightening Boost at 10% L-Ascorbic Acid is effective without being aggressive for first-time users. The powder-to-serum system is intuitive, and visible brightening typically appears within 1-2 weeks of consistent AM use. The brand's clinical data shows 66% brightness improvement in 4 weeks, making it a gift with demonstrable, fast results.

What makes this gift set better than buying the vitamin C serum alone?

This set includes the Brightening Boost Power System (worth $128) plus the Art Deco Champagne Flute and Fizzing Lemon Cubes, all for $165. It is a complete gifting experience — clinical-grade skincare paired with lifestyle items — rather than a standalone product purchase. The presentation is gift-ready out of the box.

Can the recipient switch to refills after this gift set runs out?

Yes. After using the powder in the gift set, the recipient can purchase Brightening Boost refills — Power refill at $68 or Pro refill at $108 — and continue with the existing dispenser. No new hardware needed. The gift establishes the routine; refills maintain it.

Is this gift available year-round or only at certain times?

The Brightening Boost Mixology Gift Set is available year-round on exponentbeauty.com. Exponent periodically updates pricing and promotions on gift sets — check the site for current offers before purchasing.

Why is powder vitamin C better than liquid vitamin C for a gift?

Liquid vitamin C serums begin degrading from the moment they are manufactured — Exponent's brand-commissioned stability research found leading liquid serums were already 30% below label claims on Day 1. A powder gift maintains full potency whether it sits under a holiday tree or in a gift bag for weeks before being opened. The recipient gets full-strength vitamin C from their first use.

Can a recipient use this if they have sensitive skin?

Yes. Traditional L-Ascorbic Acid serums require a low-pH aqueous base that causes irritation on sensitive skin. Brightening Boost is anhydrous — no acidic aqueous base — so it delivers 10% vitamin C without the stinging and flushing common in liquid vitamin C serums. Suitable for sensitive skin when used in the morning.
