When I’m catching up on red carpet events, the first thing I notice is the fashion.

The glitz, the glamour, and the gaudy accessories usually take center stage. But that wasn’t the case with Scarlett Johansson’s latest step-and-repeat at the Jurassic World Rebirth premiere in London on June 17.

Her incredibly smooth complexion instantly grabbed my attention (although her shimmery pink Vivienne Westwood gown was a close second).

The 40-year-old’s skin looked remarkably firm, radiant, and plump, and to no surprise, her skin care brand was to credit. Among the lineup? The Outset’s Firming Vegan Collagen Prep Serum.

The power-packed formula offers a multitude of skin care benefits because it basically does the job of four serums in one convenient, palm-sized bottle.

Its star ingredient is vegan collagen (many collagen-infused products are derived from animals), which improves firmness and smoothness and reduces the appearance of fine lines and wrinkles.

Skin care aside, the multi-tasking serum also acts as a makeup primer since it can be used as a “prep” step in your routine.

Thanks to its smoothing properties, it creates an even base so that your makeup goes on seamlessly and doesn’t pill after hours of wear (hence why it was a staple in Johansson’s recent red carpet prep, courtesy of her makeup artist Hung Vanngo).

All that to say, its potent formula is one of the many reasons why it has countless glowing reviews on Amazon. One shopper cheekily joked that their “face is tighter than [their] schedule,” calling the serum “magic in a bottle.”

They explained that their skin is “smoother” and “firmer,” adding, “If you want your skin to defy gravity while still feeling lightweight and hydrated, this is it.”

Another fan echoed similar sentiments, noting that their skin “looks so much firmer,” “feels plump,” and their “fine lines are…less noticeable.”

Lastly, a 75-year-old said the serum “dramatically improved the texture of [their] skin,” adding, “There is nothing I’ve used that is as effective as or makes me as happy.”
