Jessica Alba's The Honest Company was slapped with another lawsuit over their sunscreen products.

The lawsuit alleges that the company, which was co-founded by Alba and Christopher Gavigan, changed their formula in March and got rid of more than half of the zinc oxide, the chemical that provides sun protection, TMZ reported.

What raises the hackles of the customers is The Honest Company continued to label their sunscreen products with SPF 30 despite the reduced zinc oxide content, which got a lot of people and children burned, TMZ added. Photographic evidence of the burned kids was also included in the lawsuit, which is seeking $5 million in damages.

The Honest Company's sunscreen was described by its website as a "naturally derived, unscented, broad-spectrum (UVA and UVB) SPF mineral sunscreen." The company's website also indicated that no synthetic chemicals were put in the product and zinc oxide is the only active ingredient in it.

Last week, customer Jonathan D. Rubin also filed a lawsuit against the company claiming that their sunscreen is ineffective. According to the legal action, the consumer goods line "deceptively and misleadingly labeled and marketed its products" by calling them "natural," E! News reported. The documents stated that the company's certain products contain ingredients that are not natural, making them "ineffective."

"Based on Honest's representations that the Products were natural, [Rubin] and the Class paid a premium for the Products over comparable products that did not purport to be natural," the lawsuit reads, as quoted by E! News "Instead of receiving products that were natural, [Rubin] and the Class received the Products, which, contrary to Honest's representations, contained synthetic ingredients."

Rubin and the class members are seeking at least $5 million in damages from the company plus interest on all liquidated sums, the news outlet noted. The lawsuit specifically targeted four products: Honest Hand Soap, Honest Dish Soap, Honest Diapers, and Honest Multi-Surface Cleaner.

In a statement posted on Business Insider, Alba, 34, called the allegations "baseless and without merit."

"Our formulations are made with integrity and strict standards of safety, and we label each ingredient that goes into every product - not because we have to, but because it's the right thing to do," the "Sin City" actress said, as quoted by Business Insider. "The allegations against us are baseless and without merit. We strongly stand behind our products and the responsibility we have to our consumers. We are steadfast in our commitment to transparency and openness."

In past months, The Honest Company also received criticisms from consumers alleging that their sunscreen is ineffective. The business brand is currently valued at $1.7 billion, the news outlet added.
