The actress' line of all-natural products was the subject of a lawsuit filed earlier this month, in which a consumer claimed that a number of products contain "unnatural" and "synthetic" ingredients. It also states that The Honest Company sunscreen product is "ineffective."
The new class action suit, filed by consumer Michael Shane and obtained by PEOPLE, claims that the sunscreen is ineffective due to the company's recent removal of over half of the zinc oxide originally in the product, and displays pictures of sunburned adults and children who relied upon the sunscreen for protection.
The lawsuit states that Shane purchased the sunscreen in May 2015, and despite using it as directed "suffered a severe sunburn resulting in blistering and peeling."
It accuses The Honest Company of false advertising, stating that the company "should have known its representations regarding Honest Sunscreen's sun protection characteristics were untrue and misleading."
For themselves and others affected by the sunscreen's alleged ineffectiveness, Shane wants an injunction, unspecified general and punitive damages and court costs. It also asks for a trial by jury.
Alba, 34, spoke out on the issue on Wednesday: "It pains me that anyone doesn't have an incredible experience with Honest Company," she said on Extra.
"We have grown so quickly, we are not even four years old. What we have learned is that we need to do a better job at educating, and so next year they are going to launch a safe sun education platform around sunscreen and the difference between chemical and mineral sunscreens, and the importance of reapplication and how to apply and all of that."
Alba responded to the initial lawsuit in a statement to PEOPLE, in which she said the claims were "baseless and without merit."
And while announcing the launch of her new cosmetics line Honest Beauty on Good Morning America on Thursday, Alba also continued to defend her company.
"I created The Honest Company to give people access to safe and effective products and we are committed at The Honest Company to make sure that we use the safest and most effective ingredients," she said. "We're also committed to continue to educate our customers on how best to use our products."

Complaints about The Honest Company sunscreen began popping up across social media this summer, with several consumers posting photos of their sunburns.
At the time, the company defended its product, releasing a statement to PEOPLE in August: "Our Sunscreen Lotion was tested, by an independent 3rd party, against the protocols prescribed by the U.S. Food & Drug Administration's (FDA) monograph for over-the-counter sunscreen products. The results showed that our product is effective and safe for use as an 80 minute water-resistant (FDA's highest rating), SPF 30 sunscreen lotion in accordance with FDA regulations when used as directed."
A representative for Alba could not be reached for comment in regards to the latest lawsuit.
