Celebrity skincare launches have a predictable rhythm: a famous face, a burst of social-media excitement, and then the quieter question of whether the products are any good. Hyphen, launched in India in July 2023 by actor Kriti Sanon together with the founders of mCaffeine, grew faster than most, reportedly passing hundreds of crores in sales within its first two years. Its Golden Hour Glow Serum was there from the start. The name on the label gets attention; the more interesting story is that the ingredient list holds up well without it.
The core of the formula is 5% niacinamide and 1% alpha arbutin, and both percentages are on the label. Niacinamide at 5% is the concentration used in many of the studies that support it for uneven tone, dark spots and barrier repair. Its mechanism is distinctive: it reduces the transfer of pigment from melanocytes into surface skin cells, rather than stopping pigment from being made. Alpha arbutin fills that gap, inhibiting tyrosinase, the enzyme that drives melanin production. Pairing them makes sense, and the doses are sensible for daily, long-term use rather than aggressive, irritating ones.
The headline ingredient, though, is Kakadu plum extract, listed second and described as 25% of the formula. Kakadu plum is an Australian fruit famous for having one of the highest natural vitamin C contents of any fruit, and Hyphen markets it as 'natural vitamin C'. This needs some scepticism. The 25% refers to the amount of extract, which is a diluted water-based preparation, not the amount of vitamin C. The brand does not disclose how much vitamin C actually reaches your skin, and plant-derived vitamin C in a water-based serum is also likely to degrade over time. The extract adds antioxidants and makes a good story, but it should not be confused with a dedicated vitamin C serum.
Around the core actives, the formula is genuinely supportive. Propylene glycol, propanediol, glycerin, aloe, trehalose, a xylitol-based humectant complex, saccharide isomerate and hyaluronic acid give it significant hydrating capacity, which is a large part of the 'glow' you see immediately. Five ceramides plus a pseudo-ceramide support the barrier, panthenol and allantoin are soothing, and a small amount of lactic acid adds a touch of gentle exfoliation and acidity. A five-peptide complex rounds out the list, though it sits fairly far down and should be considered a bonus rather than an anti-ageing treatment.
In use, it is a light, slightly bouncy gel with a faint golden tint. One pump covers the face, it absorbs within a minute, and it leaves a dewy finish without stickiness for most people, although a few reviewers find it slightly tacky under makeup. There is no added fragrance, which matters for a daily serum. Some very sensitive users may notice a brief tingle from the lactic acid or propylene glycol.
What about results? Hydration makes skin look brighter and more even almost immediately. The brand's claim that 96% of users saw visibly glowing skin in two weeks comes from a consumer study of 32 people run in an accredited lab in 2023, mostly based on self-assessment. It's a reasonable signal that people enjoyed using it, not evidence of measurable pigment reduction. Realistically, dark spots and post-acne marks fade over eight to twelve weeks of daily use, and only with consistent sunscreen; without sun protection, any brightening serum is fighting a losing battle.
It pays to note that the formula seems to have been revised since launch; ingredient databases list an older version. The current list on the brand's site is the one reviewed here, and it is the one to check if you buy from a third-party seller.
Value is one of the serum's strongest points. In India, 30ml costs ₹649, often discounted, which is very affordable for a serum with this many actives at meaningful doses. The catch for international readers is availability. Hyphen is essentially an Indian brand, and the serum is sold mainly through the brand site and Indian retailers. Buying it abroad means import fees that erase much of its price advantage.
On hype: Hyphen's marketing leans heavily on celebrity, percentages and the word 'glow', and some claims, especially around Kakadu plum, overreach. But the brand deserves credit where it is due. The serum is fragrance-free, the actives are disclosed with percentages, and the formula is built on ingredients with real evidence. This is a case where the hype is louder than necessary for a product that is fundamentally sound.
It also fits neatly into a simple routine, which is the brand's whole pitch. Because niacinamide and alpha arbutin are both gentle, the serum can be used morning and night without the cycling that stronger actives demand, and it layers comfortably under sunscreen. People already using a retinoid can keep it to the morning, where it pairs naturally with sun protection, and leave the evening for the retinoid. Those with acne-prone skin will appreciate that it is oil-free and light, and niacinamide has its own modest evidence for reducing oiliness. If you are building a first routine on a budget, this serum, a basic moisturiser and a good sunscreen cover a surprising amount of ground.
Who should buy it? Anyone in India with dullness, uneven tone, post-acne marks or mild pigmentation who wants an affordable, gentle daily serum. It suits oily, combination, normal and dry skin, and most sensitive skin. Who should skip it? People who need a strong vitamin C serum, anyone with melasma that needs a medical plan, and international buyers who would pay import prices for something they can find closer to home.
