This $15 anti-aging serum delivered ‘impressive results in very little time'
Growth factors are fast becoming the next buzz-worthy skincare ingredient. They are proteins that naturally occur in our skin cells — simply put, they act as messengers to various mechanisms in the skin, signaling it to repair and rejuvenate. They do so by stimulating skin cell turnover and the production of collagen and elastin — the fundamentals of keeping skin smooth and firm.
With age, growth factors deplete, so the skin is less able to repair itself from environmental damage like UV light and pollution, leading to premature signs of aging. By replenishing these growth factors, old skin cells start acting like younger skin cells again.
The science isn't new — growth factors were first discovered by scientists in the 1950s who went on to win a Nobel Prize for their work, and luxury skincare brands started infusing their formulas with the regenerating ingredient in the 1990s. But what is new is having access to this advanced science for the first time at a bargain price.
Typically, it's only high-end and hugely expensive skincare brands that carry growth factor skincare, excluding The Inkey List's offering, although it's hard to compare when it's not as highly concentrated. But The Ordinary's serum is cheap at $15.50 — so I wanted to see how it performed.
How I tested
I am an experienced beauty editor in my 40s with typical signs of skin aging, including pigmentation, fine lines, and a loss of firmness. I tested the product every day for three weeks (both in my morning and evening skincare routines) under the same moisturizer.

Dow briefly hits record high on UnitedHealth's gains; data in focus
Aug 15 (Reuters) - The blue-chip Dow briefly hit a record high on Friday, as UnitedHealth's shares jumped after Berkshire Hathaway raised its stake in the health insurer, while investors assessed mixed data to gauge the Federal Reserve's monetary policy path this year. UnitedHealth Group (UNH.N), opens new tab gained 11.6% to hit a more than two-month high after Warren Buffett's company (BRKa.N), opens new tab revealed a new investment in the health insurer, while Michael Burry's Scion Asset Management also turned more bullish on the company. Rising costs in the broader healthcare sector and an about 40% slump in heavyweight UnitedHealth's shares this year have left the Dow (.DJI), opens new tab lagging its Wall Street peers on the road to record highs. The price-weighted index last scaled an all-time high on December 4. This week, however, the healthcare sector (.SPXHC), opens new tab is the top performer on the S&P 500 and is on track for its best weekly performance since October 2022. Other insurance stocks Centene (CNC.N), opens new tab and Molina (MOH.N), opens new tab gained 5.2% each. A report showed retail sales in July rose as expected, but the University of Michigan's index tracking consumer confidence fell more than expected to 58 as inflation expectations rise. "As long as consumer spending holds up and companies are able to retain workers because of that robust spending, the flywheel can continue to spin, pushing corporate profits and stock prices higher," said Chris Zaccarelli, chief investment officer for Northlight Asset Management, speaking on the retail sales figures. At 10:11 a.m. ET, the Dow Jones Industrial Average (.DJI), opens new tab rose 99.11 points, or 0.22%, to 45,011.45, the S&P 500 (.SPX), opens new tab lost 7.39 points, or 0.11%, to 6,461.15 and the Nasdaq Composite (.IXIC), opens new tab lost 30.70 points, or 0.14%, to 21,681.10. Wall Street's main U.S. stock indexes are on track for their second week of gains, buoyed by expectations that the Fed could restart its monetary policy easing cycle with a 25-basis-point interest rate cut in September. The central bank last lowered borrowing costs in December and said U.S. tariffs could add to price pressures. However, recent labor market weakness and signs that tariff-induced inflation was yet to reflect in headline consumer prices have made investors confident of a potential dovish move next month. Still, Chicago Fed President Austan Goolsbee said recent data reports showed a stagflationary impulse from tariffs on the economy. On the trade front, U.S. President Donald Trump said he would unveil tariffs on steel and semiconductors next week. Applied Materials tumbled 11.3% after the chip equipment maker issued weak fourth-quarter forecasts. Intel (INTC.O), opens new tab rose 3% after a report said the Trump administration was in talks for the U.S. government to potentially take a stake in the chipmaker. Attention was also on a meeting between Trump and Russian counterpart Vladimir Putin that markets hope could pave the way for a resolution to the Ukraine conflict. The meeting will take place at 1900 GMT. Declining issues outnumbered advancers by a 1.22-to-1 ratio on the NYSE and a 1.31-to-1 ratio on the Nasdaq. The S&P 500 posted 8 new 52-week highs and no new lows while the Nasdaq Composite recorded 52 new highs and 45 new lows.

Hiker who died after being bitten by venomous snake in Tennessee made fatal mistake, officials believe
A hiker who died of a snake bite in a scenic state park in Tennessee made one fatal mistake: he reportedly picked up the venomous reptile. The man, who has not been identified, was just half a mile down a trailhead at Savage Gulf State Park when first responders arrived at about 12.30 p.m. last Friday, according to the Grundy County Emergency Management Agency. After life-saving efforts administered by rescue workers, the man was transferred to a local hospital, where he succumbed to his injuries. A representative for Grundy County EMA said the hiker was likely bitten by a timber rattlesnake, a highly venomous species found in the eastern U.S. Witnesses who spoke to first responders said they saw the hiker pick up the snake, which bit him on the hand, Matthew Griffith of the Grundy County EMA told ABC News Channel 9. The man was believed to have died of an allergic reaction, though the full cause of death has yet to be released. It was not immediately clear why the victim picked up the snake. 'The family of the individual will be in our thoughts and prayers,' Griffith said. 'As always, it's strongly recommended to have some kind of first aid supplies while enjoying outdoor recreational activities and be mindful of wildlife and the dangers that some wildlife may pose.' Griffith urged those who encounter any snake to remain calm and not attempt to handle it. The Grundy County EMA website describes timber rattlesnakes as the 'largest, and the most dangerous, of the four venomous snakes in Tennessee.' They can be up to 5ft long with a large, distinctive triangular head, vertical pupils, and a characteristic rattle at the end of their tail. In most cases, however, rattlesnake bites are not fatal. Less than one in 600 bites results in death, according to the U.S. Forest Service. Bites from timber rattlesnakes are rare, according to the Smithsonian's National Zoo and Conservation Biology Institute. The species is considered more docile than other members of its reptilian family. Timber rattlesnakes typically prey on small rodents and often remain motionless if encountered in the wild.

Biomechanics study shows how T. rex and other dinosaurs fed on prey
WASHINGTON, Aug 15 (Reuters) - Tyrannosaurus subdued prey with raw power, using bone-crushing bite force. But other meat-eating dinosaurs that rivaled T. rex in size used different approaches. Giganotosaurus relied more on slashing and ripping flesh. And the long and narrow snout of Spinosaurus was well-adapted for catching fish. Researchers have documented the feeding biomechanics of meat-eating dinosaurs in a comprehensive analysis of the skull design and bite force of 17 species that prowled the landscape at various times from the dawn to the twilight of the age of dinosaurs. The study found that Tyrannosaurus possessed by far the highest estimated bite force, with a heavily reinforced skull and massive jaw muscles. But it showed that other dinosaur predators evolved successful approaches to bringing down prey even without matching the T. rex chomp. "We found that large predatory dinosaurs didn't all evolve the same kind of skull to deal with the challenges of feeding at massive size," said vertebrate paleontologist Andre Rowe of the University of Bristol in England, lead author of the study published this month in the journal Current Biology, opens new tab. "Some, like T. rex, reinforced the skull to tolerate extremely high bite forces and the associated skull stresses. Others, like Allosaurus or Spinosaurus, went with lighter or possibly flexible builds that spread out stress in different ways. There's no single 'correct' way to be a giant meat-eater, and that's the point," Rowe added. The study focused on species within the group, or clade, called theropods that includes the meat-eating dinosaurs. They ran from Herrerasaurus, which lived in Argentina about 230 million years ago and is one of the earliest-known dinosaurs, all the way to T. rex, which was present in western North America when an asteroid struck Earth 66 million years ago and ended the age of dinosaurs. The researchers used three-dimensional models of the skulls of the 17 species, including two different specimens of Tyrannosaurus, and applied a method for simulating how structures respond to physical stress. They estimated muscle forces using digital muscle reconstructions based on living relatives of the dinosaurs - birds and crocodiles - then applied those forces to the skull models to simulate bites. "Our focus wasn't raw bite force. We were testing how the skulls distributed that force under load, and how these distributions varied by each lineage of carnivores," Rowe said. The early theropods examined in the study such as Herrerasaurus, which lived during the middle of the Triassic Period, and Dilophosaurus, which lived early in the Jurassic Period, exhibited much lower stress resistance than their later counterparts. They were lightly built dinosaurs and not well adapted to high bite forces, Rowe said. The increase in bite force and skull strength unfolded gradually over time, reaching its apex with Tyrannosaurus and its close relatives in a lineage called tyrannosaurs such as Daspletosaurus and Albertosaurus, which like T. rex appeared late in the Cretaceous Period. "In tyrannosaurs, there's a big jump in skull strength and bite mechanics, coinciding with deeper skulls, more robust bone architecture and changes in jaw muscle attachment. So the ramp-up wasn't immediate. It evolved over time and in certain lineages more than others," Rowe said. Tyrannosaurus, Giganotosaurus and Spinosaurus were three of the largest theropods, but their skulls were quite different. Perhaps the largest-known Tyrannosaurus is a specimen named Sue at the Field Museum in Chicago, at 40-1/2 feet (12.3 meters) long. Giganotosaurus and Spinosaurus rivaled T. rex in size. Giganotosaurus lived in Argentina in the middle of the Cretaceous, while Spinosaurus inhabited North Africa at around the same time, both predating Tyrannosaurus by roughly 30 million years. "Giganotosaurus was large, but its skull wasn't built for the same kind of high-force feeding as T. rex. Spinosaurus had a long, narrow snout, which is consistent with a diet focused on fishing, though we have fossilized evidence that it ate other animals, such as pterosaurs," Rowe said, referring to the flying reptiles that were cousins of the dinosaurs. One of the key takeaway messages, Rowe said, is that giant body size did not funnel all theropods toward the same design. Stronger bite force was one strategy, but not the only one, Rowe added. "Some animals win with raw power, others by striking quickly or repeatedly. What we're seeing here is a spectrum of ecological adaptations. These animals weren't all trying to be T. rex clones. They were solving the same problem in different ways," Rowe added. "That kind of evolutionary flexibility," Rowe added, "probably helped them dominate ecosystems for so long."
