Glycolic acid is the queen bee of AHAs. Just don't overuse it
Now a constant on Instagram reels, glycolic acid gently exfoliates the top layer of your skin without causing the irritation that physical scrubs do. But it wasn't always such a big deal. This magical ingredient made its debut in 1992, when the skincare brand Avon launched ANEW , a first-of-its-kind glycolic acid-based skincare line.
Glycolic acid is the queen bee of skincare acids – small but powerful. Generally derived from sugarcane, this alpha-hydroxy acid packs some major benefits for your skin and scalp.
That said, this wonder potion still deserves a place on your dresser – for very many reasons.
Get smoother skin, feet
Glycolic acid exfoliates dead skin and fades acne scars, helping keep breakouts at bay. It's also great for anti-ageing – smoothing fine lines and wrinkles, and evening out skin tone and texture.
But moderation is key. I'm honestly quite taken aback by the sheer number of glycolic acid products in the market today – sprays, gels, pads, even deodorants. Since no skincare product seems to have escaped this fad, be careful with the dosage you apply to your skin and always consult your trusted dermatologist before doing so.
Glycolic acid can also work to smoothen the tiny dark bumps on your arms and legs – popularly known as 'strawberry' or 'chicken' skin. However, know that it can't fully fix the problem. This condition is largely influenced by genetics, ageing, and the amount of sun exposure or blood circulation in the affected areas.
While glycolic acid-based lotions and body washes can help to an extent, they can't address the root causes. Laser treatments, diligently followed up with anti-inflammatory and hydrating skincare, can help manage the condition better.
If you're someone who's struggling with cracked heels, glycolic acid might be the fix you need. It dissolves dead skin, helps soften calluses, and offers significant hydration. Just apply directly to your heels and follow up with a thick moisturiser for soft, crack-free feet.

Get a healthy scalp
Your scalp is naturally known to produce more oil than the other areas of your skin. And if you add all the residues left over by shampoos, conditioners, and styling products, you're essentially looking at a veritable cocktail from the dark side. For those of you already dealing with dandruff, the extra scaling of your skin brought about by fungal growth will only make things worse.
This is where glycolic acid comes in as the gentle but powerful exfoliator. It removes dead skin, buildup, and extra icky debris that your hair can do without. Just dab a low-concentration glycolic acid serum onto a clean scalp, leave for 30 minutes, and wash off with shampoo for dandruff and grime-free hair. Avoid usage if you're under 21, pregnant or nursing, or have a sensitive or irritated scalp.
People with bald spots can also use glycolic acid in moderation, but must apply it at night and wash off in the morning before heading off into the sun. This is because glycolic acid increases UV sensitivity, and bald spots leave the scalp particularly prone to sun damage.
Those suffering from heavy dandruff can use a combination of apple cider vinegar and cetrimide (which is found in Savlon), instead of glycolic acid. They can be far more effective.

Some dos and don'ts
Glycolic acid is a powerful friend to have in your skincare routine for exfoliation, brightening and anti-ageing – but it's crucial to use it correctly.
Start initiation slowly, adjust frequency
If you're completely new to glycolic acid, start with a two to three per cent concentration and gradually build up tolerance by using it twice or thrice a week. Do not use daily and always apply at night. Those with sensitive skin or conditions like rosacea, psoriasis, or eczema should steer clear of glycolic acid altogether.
Pair it with sunscreen
Glycolic acid increases sun sensitivity, so don't even think about using it without applying your sunscreen after. If you skip SPF, then you're inviting hyperpigmentation, sunburns, and even accelerated ageing.
Don't combine with harsh actives
Do not combine glycolic acid products with retinoids, salicylic acid, lactic acid, or vitamin C serums.
Finally, like I always tell you, consult your trusted dermatologist before using any of this on your skin.

Tom Lehrer, musical satirist, dies at 97
Tom Lehrer, an acerbic songwriter and Harvard-trained mathematician who rose to fame in the 1950s and '60s by pillorying the sensibilities of the day, has died at age 97. Lehrer died at his home in Cambridge, Mass., on Saturday. His death was confirmed by friends on Facebook. No cause of death was given. The bespectacled Lehrer began performing on college campuses and clubs across the country in the 1950s, playing the piano and singing darkly comedic numbers that he penned on topics such as racial conflict, the Catholic Church and militarism, earning him the sobriquet of "musical nerd god." In "National Brotherhood Week," which lampooned the brief interlude of imposed tolerance celebrated annually from the 1930s through the early 2000s he wrote: Oh, the white folks hate the black folksand the black folks hate the white folks,to hate all but the right folks is an old established rule …But during National Brotherhood Week (National Brotherhood Week),Lena Horne and Sheriff Clark are dancing cheek to fun to eulogizeThe people you despise,As long as you don't let 'em into your school. Lehrer's songs also took aim at then-taboo subjects such as sexuality, pornography and addiction. In 1953, his self-released album 'Songs of Tom Lehrer" became an underground hit. Produced for $40 and promoted by word of mouth, the cover image was of Lehrer in hell playing piano as the devil. It eventually sold an estimated 500,000 copies and sparked demand for concert performances around the world. During the mid-1960s, Lehrer contributed several songs to the satirical NBC news show 'That Was the Week That Was,' hosted by David Frost. The show inspired Lehrer's third album, 'That Was the Year That Was.' Released in 1965, it reached the 18th spot on American music charts. On the occasion of his 90th birthday in 2018, Los Angeles Times columnist Michael Hiltzik wrote that Lehrer's lyrics were written "with the facility of William S. Gilbert and tunes that evoked the felicity of Sir Arthur Sullivan. Lehrer's work bounced the absurdities and paranoias of that period back at us, in rhymed couplets and a bouncy piano beat." Thomas Andrew Lehrer was born in New York City on April 9, 1928, to a middle-class family. His father James Lehrer was a successful necktie manufacturer. As a child he took piano lessons but preferred Broadway show tunes — with a particular affection for the works of Gilbert and Sullivan — to the classics. After entering Harvard University at age 15, his penchant for sardonic humor surfaced in his parody song "Fight Fiercely Harvard," which challenged the football team's reputation for toughness and earned him a measure of renown on campus. For a time he followed a dual track, music and academia, though he never completed the PhD thesis he began while pursuing doctoral studies at Harvard and Columbia University. After a two-year break between 1955 and 1957 when he served in the Army, Lehrer once again performed concerts across the U.S., Canada and Europe. In a 1959 Time article, the magazine described Lehrer and fellow comedians Lenny Bruce and Mort Sahl as the symbols of a new 'sick' comedy. 'What the sickniks dispense is partly social criticism liberally laced with cyanide, partly a Charles Addams kind of jolly ghoulishness, and partly a personal and highly disturbing hostility toward all the world." Lehrer's work opened the door for generations of musical satirists including Randy Newman and 'Weird Al' Yankovic and exerted an influence on everything from the musical skits of "Saturday Night Live" to the mockumentary "This Is Spinal Tap." "He set the bar for me — and provided an example of how a nerdy kid with a weird sense of humor could find his way in the world,' Yankovic once said of Lehrer. 'Done right, social criticism set to a catchy tune always makes politics easier to digest,' Lizz Winstead, co-creator of "The Daily Show," told Buzzfeed in an article examining Lehrer's influence on modern satirical comedy. But Lehrer was first and foremost an academic, over the course of his career teaching math and musical theater at Harvard, the Massachusetts Institute of Technology and UC Santa Cruz and working for a time at the Atomic Energy Commission. He viewed entertainment largely as a sideline, and by the late 1960s had grown weary of life in the public eye. After several pauses to focus on his academic pursuits, he stepped off the stage in 1967 following a concert in Copenhagen. In 1971, he wrote songs for the PBS children's series "The Electric Company." His last turn in the spotlight was a year later. After performing at a presidential campaign rally for the Democratic nominee, South Dakota Sen. George S. McGovern, he gave up performing for good. Lehrer explained his retreat from the stage by saying that 'political satire became obsolete when Henry Kissinger was awarded the Nobel Peace Prize." In an interview with the New York Times, he elaborated: 'The Vietnam War is what changed it. Everybody got earnest. My purpose was to make people laugh and not applaud. If the audience applauds, they're just showing they agree with me.' But audiences were not through with Lehrer. After nearly a decade in self-imposed exile, Lehrer became a hit once again in the early 1980s when Cameron Mackintosh, the British theatrical producer, created "Tomfoolery," a revue of Lehrer's songs that opened in London's West End before going to to play New York, Washington, Dublin and other cities. Despite the public acclaim, Lehrer maintained a fiercely private life. He never married nor did he have children. In 2020, Lehrer announced through his website that he was making all of the lyrics he wrote available to download for free without further permission, whether or not they were published or retained a copyright. Two years later he went further in relinquishing his rights, saying: 'In short, I no longer retain any rights to any of my songs. So help yourselves, and don't send me any money.'

Boston closer Aroldis Chapman thinks he'll return soon after back spasm forces him out
BOSTON (AP) — Boston Red Sox closer Aroldis Chapman thinks he'll be able to pitch in a couple of days after walking off the mound with a back spasm in the eighth inning of Sunday's game against the Los Angeles Dodgers. 'It's just a spasm. It should be gone in a couple of days,' he said through a team translator after the Red Sox beat the Los Angeles Dodgers 4-3 for a series victory. In to face the top of the Dodgers' order, his velocity was noticeably down to mid-90 mph on his fastball instead of the high 90s to low 100s. Manager Alex Cora and a trainer came out to the mound to visit him after Shohei Ohtani flew out to the left-field warning track. Jordan Hicks entered and got out of a two-on, one-out mess when Teoscar Hernández lined to second and Ceddanne Rafaela dove to the bag, beating Hyeseong Kim for double play. Hicks pitched the ninth for his second save. 'Tight back. He should be OK,' Cora said of Chapman. Both Chapman and Cora said they didn't think there would be a trip to the injured list. 'I was definitely determined to stay out there, work through it,' Chapman said. 'Alex thought it would be better, smarter that we just 'call it' to avoid anything down the line.' The 37-year-old Chapman is having one of his better seasons in the majors with 18 saves and a 1.30 ERA, with much better control. He's walked just 11 in 41 1/3 innings. In early July he earned his 350th career save and said he'd like to reach 400. ___ AP MLB:
