Smashbox is reviving its pH-reactive O-Gloss Lip Gloss at $26, the clear-to-pink formula that millennials once hunted down on eBay in leftover original-era stock. The updated formula still shifts to a custom pink based on individual chemistry and now adds six hours of high shine, a nonsticky glass finish, visible plumping, and vitamins C and E, Smashbox said.

What is the pH-reactive revival story?

The O-Gloss return lands alongside ANFISA Skin's launch of its $29 Ceramide Lip Liner, a feather-resistant partner to the brand's NewBeauty Award-winning ceramide gloss. ANFISA describes its four-shade range as "a curated archive of smoked, burnt and bruised tones," built for lining and lightly blurring toward a '90s lip effect with gloss layered on top.

Which October launches target aging concerns?

Murad priced its Retinal ReSculpt Neck & Décolleté Lifting Serum at $109 and built it around encapsulated retinal, which the brand says is 2.5 times more effective than free retinal at firming sagging, crepey skin. In an eight-week study, 81 percent of participants reported that neck and chest lines appeared less visible in as little as two weeks, Murad said.

SK-II extended its PITERA franchise into a jelly-textured Facial Treatment Serum ($139), the first time the fermented ingredient has been paired with Boosting Oil Pearls. Each 1.7-ounce bottle carries 16,000 of the pearls, which burst on contact without an oily residue. After seven days of use, skin looks firmer and plumper; after 28 days, fine lines look softer, SK-II reported.

LOoPHA's Helium Hand Cream ($22) is positioned as a temporary fix for volume loss in the hands. Blackberry fruit extract targets the look of firmness while brown seaweed extract supports collagen to smooth crepey texture, the brand said. The cream carries notes of bright citron zest, soft black pepper, fresh cypress, and warm amber.

What replaced Dior's cult-favorite Face & Body Foundation?

Dior's new Backstage Glow-Up Skin Tint ($55) is a gel-cushion formula in 24 shades built for light-to-medium buildable coverage. Biotech-derived fragmented collagen visibly plumps and hydrates for 24 hours, broad-spectrum SPF 20 adds UV protection, and the waterproof, crease-proof finish is designed to last all day, according to Dior. The launch is the brand's pivot from full-coverage base toward a "my skin but better" finish.

Which hair launches clean up second-day hair?

TRUHAIR's Dry Shampoo Pressed Compact retails at $30 and replaces aerosol with a puff-applied powder that combines oil-absorbing powders with hydrolyzed soy, wheat, and milk proteins, plus quinoa, goji berry, strawberry, and black mulberry extracts. A built-in mirror supports gym and travel touch-ups.

Redken's Acidic Cleansing Mist Dry Shampoo costs $32 and uses glycolipids and an advanced cleansing complex to break down up to four days of oil, buildup, and odor at the root. The brand's Acidic pH technology leaves the scalp feeling just-washed with no chalky residue, Redken said.

What else shipped in October?

• Sofie Pavitt Face Temp Check Hot & Cold Therapy Mask Duo ($90): Step one is a warming enzyme mask with papain, bromelain, tranexamic acid, and niacinamide. Step two cools skin with centella and polyglutamic acid. Leave each on for 10 to 15 minutes once or twice weekly.
• KUSSHI Beauty Organizer ($49): A foldable, water-resistant neoprene case with a mesh pocket for palettes and lipsticks, six cushioned brush slots, and a machine-washable shell available in bright pink and leopard print.
• OLLY Sleep Mochi Bites ($18 for a one-month supply): Japanese-inspired chews combining 5 mg of melatonin with magnesium and chamomile extract. Take two chews (1 gram of sugar total) 30 minutes before bed in a blueberry-starfruit flavor.

The October slate suggests prestige and indie brands are leaning harder into sensorial formats, pH-responsive color, and heritage revivals ahead of the holiday retail window.
