"This is 52. No make up. No filters. Happiness. Sprinkle that s -- t everywhere," Milano, 52, wrote via Instagram on Thursday, December 19. "I love you all. Even the trolls. If you can hate a stranger -- I can love a stranger. So...I love you. 🥰."
Alongside the message, Milano shared a selfie as she leaned back against a pillow and gave a soft smile. "Edit: yes, my eyebrows are micro-bladed," Milano added.
This isn't the first time Milano has dared to go bare on social media. She previously kicked off her 51st year with a fresh face selfie -- and a message for her followers. "Today is my birthday! #nomakeupselfie #nofilter #iwokeuplikethis," Milano captioned her Instagram post at the time.
"Today is my birthday! However, instead of just saying my age, from now on I'm going to say that I have reached 'level 51,'" she wrote. "To unlock this level, I have discovered a few cheat codes that have helped me navigate the challenges and triumphs alng the way. The first cheat code is RESILIENCE. I have faced my fair share of heartache, anxiety, and depression, but I have managed to overcome them with LOVE."
"Love for myself, which keeps me evolving and searching, love for others, which keeps me gentle and forgiving, and love for the world around me which keeps me in awe at what has been created here," Milano continued. "It is through this love that I have found the strength to keep pushing forward."
Milano explained that another "cheat code" has been gratitude. "I have learned to appreciate the simple joys of life, like the beauty of birds soaring through the sky and the majesty of trees standing tall," she wrote. "I am grateful for the symbiotic relationship between plants and humans, where my breath nourishes them, and their existence provides me with what I need to survive."
Milano noted that gratitude has allowed her to "embrace the gift of curiosity, never ceasing to learn something new."
"Mostly, I am grateful for the beating of my heart, which carries the blood of my ancestors and connects me to a rich lineage of profound triumph," she said.
The Charmed star noted that two more "cheat codes" were compassion and empathy.
"Although they can sometimes be uncomfortable emotions to experience, they have shaped me into a kind and humble person who strives to ease the suffering of humanity," Milano wrote. "The ability to want to understand and share the feelings of others has allowed me to forge deep connections and foster a sense of unity and community."
Above all, Milano shared that the "most significant factor" in reaching her new age "is the people in my life who love me unconditionally."
"Their support, care and acceptance have been the driving force behind my personal growth," she wrote. "Today, my heart overflows with gratitude for their presence."
Miano concluded her message by noting that she has a "sense of accomplishment and gratitude" as she celebrates her milestone. "I embrace the challenges and joys that lie ahead, knowing that I have the cheat codes of resilience, gratitude, compassion, empathy, and the love of those around me to guide me through this game of life."
