In a video posted to Instagram on Tuesday, the 53-year-old star shared her tips and tricks to achieving a "beautiful glow" ahead of her Met Gala glam.
"First step is, of course, the holy grail That JLo Glow beauty serum," a bare-faced Lopez tells the camera.
"Next step is...I put on my SPF," Lopez says while holding her JLo Beauty That Big Screen Moisturizer with Broad Spectrum SPF 30.
"I think people think of me as bronzy and like always in the sun and stuff like that, but the truth is I did not take a bunch of sun," she tells the camera. "I did do self-tan, bronzers and all kinds of things like that."
"But no sun and sunscreen every single day," she reiterates.
'The holy grail: That JLo Glow beauty serum'
Earning an average rating of 4.1 out of five from Sephora shoppers, reviewers call the JLo beauty product the "holy grail of serums."
The face serum "does some heavy lifting," writes one shopper. "It balances out my skin tones and removes redness."
"This serum is one of the best I have ever used," echoes another. "My skin literally glows and is bright every time I use it."
The serum is a "chef's kiss for me," praises a third reviewer. "I have dry skin, and it makes my face feel and look great. Treat yourself to this product and you won't regret it," they write.
While the celebrity-backed serum has earned hundreds of five-star reviews, some note it "doesn't mix well" with other skincare products and "only works well when used alone."
"[I] experience piling with my foundation and it never sits right," according to one Sephora shopper.
Based on a clinical study, 91 per cent of participants noted an improvement in the look of their skin's firmness and elasticity, and 100 per cent agreed it improved skin hydration and texture.
However, a handful of reviewers note that as it's an anti-aging product, "younger ladies might not need or want such a heavy serum."
