This HBO Star's Glowing Skin Is Thanks to a $19 Amazon Face Serum

If you're not watching HBO's The White Lotus, ooomg — you must. The soundtrack is practically begging for an Emmy, paired with phenomenal performances from Connie Britton, Jennifer Coolidge, Natasha Rothwell, Sydney Sweeney, and Jake Lacy (sidenote: If you're suitably repulsed by his character, these photos are a palate cleanser). A lot of time is spent tracking Alexandra Daddario's reactions as his new fiancé, so her expressive eyes and glowing skin are at the forefront. And as the actress revealed, that glow is partially thanks to an inexpensive Amazon best-seller.

Daddario demonstrated her expansive skincare routine to Vogue last month, and scattered among pricey buys like Vintner's Daughter, Eminence Organics, and Epicuren were a few effective picks from the low end of the price spectrum. Andalou Naturals' aesthetician-loved glycolic mask earned a shoutout, and none other than Amazon's best-selling TruSkin Vitamin C Serum made an appearance.

"I use a vitamin C serum, which I've only recently started using. Topical vitamin C is great," she said. As the actress explained, her sensitive skin sometimes reacts to heavy makeup, stress, and sun exposure by breaking out in vicious acne (sounds about right). The Vintner's Daughter serum pulls its weight by soothing flare-ups — and according to almost 100 of the TruSkin's 10,000 five-star reviews, its effect on stressed out skin and sun damage is nothing short of remarkable.

"I am a 43-year-old wife, mom of teen girls, and middle school math teacher. That equals stress on my skin," writes one shopper — no kidding. "I also live in Texas (read: sun damage). Two weeks of using this serum, and my 17-year-old tells me I look like I am in my 20s... Fine lines are going away. Acne scars, fading. Pigmentation evening out. Even my neck and jawline are smoother."

I'd expect nothing less from Amazon's top-selling face serum, which beats 2,000+ competitors for the spot — even fellow best-sellers from CeraVe, Eva Naturals, CosRx, and Vichy. There's a reason why the TruSkin's gained over 54,000 five-star ratings on the site, with rave reviews rolling in for its effect on dullness, wrinkles, and sagging skin in a matter of weeks.

"My complexion was okay until after I turned 60. I started having problems with discoloration, sagging skin, enlarged pores, and old acne scars beginning to show," writes another person. "The TruSkin serum seems to have reversed those problems. Spots and scars are less pronounced, and some have even faded to near invisible. My skin is also firmer and brighter."

Over 300 reviewers called out the serum's transformative properties for wrinkles, including one reviewer who says they smoked for 20 years and saw results after a week. Even 82-year-olds say the formula erased creases and lightened deep lines, and while there's absolutely nothing wrong with laugh lines, avid gardeners in sunny California say it plumps them as it shrinks pores and evens out skin tone.

Its effect on breakouts is also superb, according to reviewers who still deal with acne later in life. Dull skin recedes as well, per fans who say the serum makes them "look alive again". Read through just a handful of the TruSkin Vitamin C Serum's reviews, and it becomes as clear as devotees' skin: To paraphrase Star Wars, this is the solution you've been looking for.
