C-Luma Hydrabright Gentle Hydrating Vitamin C Serum

Drunk Elephant C-Luma Hydrabright Serum is a 10% vitamin C serum built on gentler derivatives rather than straight l-ascorbic acid. Drunk Elephant aims it at brightness, clarity and hydration together, which is why the skin-concern list runs from dark spots and breakout marks through to redness and dryness.

Skin types	Normal, dry, combination and oily
Targets	Dark spots, dullness, redness, blemishes, dryness, texture, lines, slackness
Strength	10% vitamin C in total
The breakdown	Sodium ascorbyl phosphate 9.0% · ascorbyl glucoside 1.0%
Good to know	Vegan · cruelty-free · recyclable packaging

What it actually does

• Sodium ascorbyl phosphate carries most of the load. At 9.0%, it is credited with visible brightening, fewer blemishes, and improvement in how elasticity, fine lines and wrinkles look.
• Ascorbyl glucoside adds protection. The remaining 1.0% is listed as defending against UV damage and free radicals while working on hyperpigmentation.
• A triple-antioxidant brightening complex. Glutathione, phloretin and diglucosyl gallic acid together are known for reducing how hyperpigmentation appears.
• Fades post-breakout marks. That is called out specifically alongside general pigmentation, which is useful if your dark spots came from acne.
• Hydrates immediately and over time. Both timeframes are part of the brand's claim.
• What the clinical study reported. With 30 people: hydration rose by 109% on contact; everyone showed improvement in elasticity at four weeks; 93% had brighter skin by twelve weeks; and hyperpigmentation, texture and tone all improved by week eight. Brand-run study — individual results vary.
• Built to be mixed. Drunk Elephant designs its products to be combined in the palm, with Umbra, their sunscreen, as the exception since it is meant to sit on top blocking UV.

How to use

1. One pump on clean, dry skin, morning or evening — and alongside any other Drunk Elephant serum, treatment or moisturiser.
2. Top it with sunscreen. The brand's tip is to finish with one of its Umbra Mineral Cream sunscreens, sold separately, so the antioxidant work is paired with UV protection.
3. The brand's smoothie suggestion: blend a pump of this with a pump of Lala Retro in your palm and apply both at once, then follow with a broad-spectrum sunscreen. Each product is bought on its own.

Recycling: pop the top off, unscrew the clear vial from it, then recycle both the vial and the outer container.

Questions

Why is this described as gentle?

Because of what the 10% is made of. Sodium ascorbyl phosphate and ascorbyl glucoside are vitamin C derivatives rather than pure l-ascorbic acid, which is why redness and sensitivity sit on the list of concerns this one addresses.

Morning or night?

Either works — one pump on clean, dry skin. If you use it in the morning, the brand wants sunscreen over the top; that pairing is what it describes as maximising the antioxidant benefit.

Can I mix it with other products?

Yes — that is the brand's whole approach. It can be combined with any of their serums, treatments or moisturisers. The one they keep separate is Umbra, their sunscreen, which stays on the surface.

How long until dark spots look different?

In the brand's study the hyperpigmentation, texture and tone improvements came at the eight-week mark, with brightness recorded at twelve weeks. Hydration was the only immediate result.
