What Are Under-Eye Injectables?
Under-eye injectables are treatments designed to improve the appearance of the delicate skin beneath the eyes. These include both volumising fillers and non-filler options such as skin boosters and regenerative injectables. Unlike tear trough filler, which adds volume to fill hollows, non-filler under-eye injectables focus on improving the quality of the skin itself. They work by:- Increasing hydration within the skin
- Stimulating collagen and elastin production
- Strengthening thin or fragile skin
- Reducing fine lines and improving texture
Under-Eye Injectables Explained: Polynucleotides, Sunekos, Jalupro and NCTF®
The under-eye area is one of the most delicate and complex parts of the face. It is often the first area where signs of fatigue, ageing, and stress become visible. Many patients assume that tear trough filler is the best or only solution for dark circles, hollowness, or tired-looking eyes. However, this is not always the case. In many patients, the main issue is not volume loss but poor skin quality. Thin, dehydrated, or damaged skin can create shadows, fine lines, and a hollow appearance even when volume is not significantly reduced. This is where modern under-eye injectables offer a different approach. Treatments such as polynucleotides, Sunekos, Jalupro, and NCTF® are designed to improve the skin itself rather than simply filling space. These treatments are often referred to as skin boosters or regenerative injectables, and they focus on restoring skin health over time. Instead of creating immediate volume, they work gradually to strengthen the skin, improve hydration, and support natural collagen production - leading to more natural and longer-lasting results.Why Under-Eye Skin Needs a Different Approach
The skin under the eyes behaves very differently from the rest of the face, which is why treatment must be carefully selected. This area is:- Extremely thin, making veins and shadows more visible
- Prone to dehydration, which worsens fine lines and dullness
- More sensitive to inflammation, leading to puffiness or irritation
- Slower to regenerate collagen, especially with age
- Improving skin thickness and resilience
- Supporting collagen and elastin production
- Enhancing hydration from within
- Reducing inflammation and improving skin quality

Types of Under-Eye Injectables: Non-Filler Alternatives to Tear Trough Filler
Non-filler under-eye injectables focus on improving skin quality rather than adding volume. These treatments work by boosting hydration, stimulating collagen, and strengthening the delicate under-eye area for more natural results over time.-
Polynucleotides - Deep Regeneration and Skin Repair
- Stimulate collagen and elastin production

How Do You Choose the Right Under-Eye Treatment?
Choosing the right treatment depends on identifying the root cause of your concern.- Thin, fragile, crepey skin → Polynucleotides
- Fine lines and early laxity → Sunekos
- Mild changes or maintenance → Jalupro
- Dullness and dehydration → NCTF®
When Injectables Alone Are Not Enough
While these treatments are highly effective for improving skin quality, it is important to understand their limitations. For example, patients considering tear trough filler swelling stages should also understand that fillers mainly address volume loss, not skin quality or excess fat. They do not:- Replace significant volume loss
- Remove prominent under-eye bags
- Correct deeper structural ageing changes
Final Thoughts
Under-eye rejuvenation has evolved beyond simply using filler. Today, the focus is on improving skin quality, supporting natural regeneration, and choosing treatments based on individual needs rather than a one-size-fits-all approach. By selecting the right treatment or combination of treatments, you can achieve more natural, subtle, and long-lasting results.Frequently asked questions
