They are composed primarily of three key amino acids\u2014proline, glycine, and hydroxyproline\u2014which are the very building blocks your body naturally uses to repair skin tissue and maintain elasticity. Because these are endogenous (naturally occurring) substances, your immune system typically recognizes them as &#8220;self&#8221; rather than &#8220;invaders,&#8221; making a direct allergic or inflammatory acne response extremely rare.+1<\/p>\n\n\n\n<p id=\"p-rc_3549a513e3206bd4-20\">However, the &#8220;collagen-acne&#8221; debate often centers on a specific hormone: Insulin-like Growth Factor 1 (IGF-1). While dairy is a well-known trigger for raising <a href=\"https:\/\/en.wikipedia.org\/wiki\/Insulin-like_growth_factor_1\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">IGF-1<\/a> levels (which can stimulate sebum production and clog pores), high-quality collagen peptides generally have a low glycemic index and do not cause the same insulin spikes. Unless you are consuming an excessive amount of protein that triggers a systemic metabolic shift, pure hydrolyzed collagen is not a direct comedogenic agent.

Maltodextrin, in particular, has a higher glycemic index than table sugar, which can cause rapid insulin spikes. These spikes signal your body to produce more androgen hormones and sebum, leading directly to clogged pores. Furthermore, artificial sweeteners can disrupt your gut microbiome, which is intrinsically linked to skin inflammation.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"B_High_Sugar_Content\"><\/span>B.\u9ad8\u7cd6\u5206<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Many &#8220;flavored&#8221; collagen sticks (like vanilla or berry) are packed with cane sugar or corn syrup to mask the natural earthy taste of bovine or marine peptides.
