If you've looked at collagen supplements, you've probably seen 'Type I', 'Type II', and 'Type III' mentioned. The names sound technical, but the differences matter when you're building a routine.
Type I collagen is the most abundant type in the body. It's the structural backbone of skin, tendons, bones, and connective tissue — the things that give your skin firmness and your joints resilience. Most skin-focused routines centre on Type I because of this role.
Type II collagen is specialised for cartilage. If you're supporting joint flexibility or mobility, Type II appears in formulas designed for that — it's less common in skin routines, more common in joint-support stacks.
Type III collagen works alongside Type I. It's present in skin, blood vessels, and the organs. Many collagen supplements use a blend of Type I and Type III for this reason — they work together.
When choosing a collagen supplement, look at what type it contains. If you're building a skin routine, Type I or a Type I + III blend is the standard. Read the pack, check the serving, and stay consistent for 6-8 weeks before assessing.
On a tuttibear routine — our collagen gummies use Type I for skin support. Pair them with vitamin C and biotin to build a complete beauty stack that targets skin from multiple angles.
If you take medication, are pregnant, or breastfeeding, check with a healthcare professional before starting any new supplement routine.
