Not all collagen is the same. Learn the difference between collagen for skin elasticity and joint support, and how to pick the right type for your goals.
Collagen is the most abundant protein in your body, acting as the scaffolding for your skin, joints, bones, and more. As you age, natural collagen production declines, which can lead to fine lines, reduced skin elasticity, and joint discomfort. That’s why collagen supplements have become a staple in many wellness routines.
But not all collagen is created equal. The type of collagen you choose—and the formula it comes in—can make a big difference depending on whether your primary goal is glowing skin or supple joints. In this guide, we’ll break down the differences between collagen for skin vs. joints, explain type 1 vs type 2 collagen, and help you pick the right supplement for your needs.
Understanding Collagen Types: Type 1 vs Type 2
Collagen comes in several types, but the two most relevant for supplements are type 1 and type 2. Type 1 collagen is the most abundant in your body and is found in skin, bones, tendons, and ligaments. It’s the primary structural protein responsible for skin firmness and elasticity, so it’s the go-to for anti-aging and skin health.
Type 2 collagen, on the other hand, is the main collagen found in cartilage, the tissue that cushions your joints. It’s specifically studied for joint comfort and mobility. While some supplements contain a blend of both, choosing a formula that targets your primary concern can be more effective.
- Type 1 collagen: best for skin elasticity, hair, and nails.
- Type 2 collagen: best for joint support and cartilage health.
Collagen for Skin: What to Look For
If your main goal is to improve skin elasticity, reduce fine lines, or support a radiant complexion, you’ll want a collagen supplement rich in type 1 collagen. Look for products that specify 'type 1' or 'type 1 and 3' on the label, as these are the types most associated with skin health.
Hydrolyzed collagen (also called collagen peptides) is broken down into smaller particles that are easier for your body to absorb. Many skin-focused formulas also include added vitamin C, which is necessary for collagen synthesis. When shopping, check for these features to get the best collagen for skin elasticity.
- Opt for hydrolyzed collagen peptides for better absorption.
- Look for added vitamin C to boost collagen production.
Collagen for Joint Support: What to Look For
For joint support, type 2 collagen is the key. It’s often sourced from chicken sternum or other cartilage-rich tissues and is typically taken in smaller doses than type 1. Some joint formulas combine type 2 collagen with other ingredients like hyaluronic acid or MSM to further support joint comfort and mobility.
If you’re an active person or experience occasional joint stiffness, a type 2 collagen supplement may be more beneficial than a general skin formula. However, some products offer a dual approach, combining both types for overall support. Consider your activity level and specific joint concerns when choosing.
- Type 2 collagen is often taken in smaller doses (e.g., 40-80 mg daily).
- Combining with hyaluronic acid may enhance joint lubrication.
Comparing Popular BERA Collagen Options
BERA offers two distinct collagen products that cater to different needs. GLOW Collagen (Liquid) is formulated to support skin elasticity and a radiant complexion, making it a great choice if your focus is on beauty from within. It’s rich in type 1 collagen and is designed for daily use.

On the other hand, FLEX Collagen (Liquid) is tailored for joint support, providing type 2 collagen to help maintain cartilage and promote mobility. If you want both benefits, you might consider the BERA Collagen Duo (FLEX + GLOW) to address skin and joints simultaneously. Each product can be taken on its own or combined, depending on your goals.

- GLOW Collagen (Liquid) targets skin elasticity and hydration.
- FLEX Collagen (Liquid) focuses on joint comfort and flexibility.
How to Choose the Right Collagen for You
Start by identifying your primary goal. If you’re noticing fine lines or loss of firmness, a type 1 collagen like GLOW is your best bet. If you’re an athlete or have joint discomfort, FLEX with type 2 collagen is more appropriate. For comprehensive support, a combination of both can be beneficial.
Also consider the format. Liquid collagen is convenient and often absorbs quickly, while powders can be mixed into drinks or foods. Think about your daily routine and what you’ll stick with long-term. Consistency is key to seeing results, so choose a formula you’ll enjoy taking every day.
- Assess your skin and joint health to determine priority.
- Choose a format (liquid, powder, or capsules) that fits your lifestyle.
Choosing between collagen for skin vs. joints doesn’t have to be complicated. By understanding type 1 vs type 2 collagen and matching the formula to your specific goals, you can make an informed decision that supports your overall wellness. Whether you opt for GLOW, FLEX, or a combination, consistency and quality are what matter most.
