Jessica Alba has penned a lengthy blog post defending The Honest Company's sunscreen line.

The actress co-authored the post on the company's official website alongside co-founder Christopher Gavigan. Over the last few weeks, customers aired out their disappointment over The Honest Company's SPF 30 sunscreen line, USA Today reported. According to users, the product doesn't have adequate sun protection and left their skin burned.

According to the 34-year-old "Sin City" star, The Honest Company is comprised of a devoted team of employees, parents, and partners who cautiously review their sunscreen products to make sure it reaches "highest standards prior to release," the blog post said.

"Protecting our loved ones and yours is the reason we founded The Honest Company. As parents, it pains us to hear that anyone has had a negative experience with our Sunscreen. We develop and use Honest Sunscreen to protect our own children - Honor, Haven, Luke, Evie, and Poppy - at the park, in the pool, outside, every day. As with everything we do, we take sun protection seriously here at Honest," the statement reads.

The post on The Honest Company's website also said that they redesigned their sunscreen lotion, supplying it with an 80-minute water resistance and an improved formula that provides easier application and a lighter-weight feel to the skin.

In addition, the company said that they have passed "extensive third-party testing in accordance with government regulations," and that they got the best score possible from the Environmental Working Group (EWG), the statement added.

Earlier this week, The Honest Company issued a statement via PEOPLE maintaining their stand on the sunscreen's efficiency and safety. The public response also said that the complaints they received on their website about the product comprise less than one half of one percent of what was sold.

NBC Chicago reported that the FDA requires sunscreen products to use up to 18% to 25% of zinc oxide. The Honest Company, however, dropped the amount of zinc oxide in the sunscreen tubes from 20% to 9.3%. The company explained that despite lessening the zinc, they compensate by putting other ingredients to maintain the product's efficiency.

Other mainstream sunscreen brands use chemicals like avobenzone, oxybenzone, and ecamsule, among others, in their products, Today wrote.

Dr. Debra Wattenberg, a New York City dermatologist at NY Skin Rx, said that the FDA does not conduct tests of sunscreen products, adding that eco-friendly merchandise aren't always better than others, the news outlet reported.

"This is a very loose term that is not regulated by anyone. The term organic can mean whatever the company wants it to be and natural can mean whatever the company wants it to be," Wattenberg said, as quoted by Today.
