In the world of modern wellness, I have spent a significant amount of time researching and experimenting with various bio-hacks. Recently, the focus has shifted toward the *peptide* industry. While I have enjoyed exploring how these amino acid chains can influence biological pathways, my journey has taught me that caution is paramount. Because I prioritize my long-term vitality, I have become deeply interested in the question: who should avoid using peptides?

Many people ask me about topical applications. While *peptides* are generally well-tolerated in skincare, *sensitive or acne-prone skin types* should approach them with care. I have found that *to avoid* irritation, it is best to introduce them slowly.
