In an Instagram caption, he wrote, “If you or someone you know is grappling with any type of addiction, know that hope and joy are within reach, provided you’re willing to put in the effort to attain them.”

Rob Lowe, the 59-year-old actor, announced in an Instagram post on Wednesday that he is celebrating a significant achievement: 33 years of sobriety. The post features a photo of him outside in water with a sunset in the background.

He added in the caption, “If you or someone you know is battling any form of addiction, there’s hope and joy to be found, provided you’re willing to put in the effort!” He went on to explain that he has discovered recovery and is leading a life filled with love, family, God, opportunities, friends, work, dogs, and fun.

After sharing the news, many of Lowe’s 1.9 million Instagram followers congratulated and offered supportive messages in the comment section. Among them was his 27-year-old son, John Owen Lowe, who wrote, “Proud of your recovery, opposite feeling about this selfie.”

Lowe is a father to two sons: 27-year-old John Owen Lowe and 29-year-old Matthew Edward Lowe, whom he shares with his wife, Sheryl Berkoff. At the 2015 Brent Shapiro Foundation Summer Spectacular, while accepting the Spirit of Sobriety award, Lowe credited his wife, who is now 61 years old, as the inspiration behind his decision to embark on his sobriety journey.

While accepting the award, Lowe explained, “She inspired me to get sober. She’s put up with my defects of character, as they call it. In sobriety, the lessons keep coming if you’re lucky enough to be along as long as I have. She’s stood by through all of that. And I love you very much.”

Lowe has also been a positive influence in his son John Owen’s sobriety journey. During their appearance on The Drew Barrymore Show in April to discuss their Netflix comedy series “Unstable,” Lowe presented his son with his five-year sobriety chip.

Upon receiving the gift, John Owen was at a loss for words and told his father, “I’m speechless. I usually have a witty retort. I don’t have one for that. That was very nice of you.”

In a conversation with PEOPLE in March, John Owen expressed his gratitude for his parents’ role in his sobriety journey, stating, “To be completely honest and serious about it, I’m eternally grateful to have supportive parents who were there for me in a moment when I needed help. And I know a lot of people don’t have that. And that makes me sad and also very grateful that I did, and I’ll forever be grateful for that.”
