Key Ingredients

What does EGF serum do?

This serum is designed to rebuild firmness and lift in areas where skin has lost elasticity.

EGF (Epidermal Growth Factor) signals your skin cells to produce more collagen and elastin, rebuilding firmness and lift in areas that have lost elasticity.

Combined with NAD+ (which provides cellular energy to execute that rebuild), this serum triggers genuine skin regeneration at the cellular level rather than just surface-level hydration.

How do I use it?

We recommend using this serum twice daily - morning and evening.

Apply 2-3 drops to clean, dry skin on your face and neck, then follow up with your favourite moisturizer.

Consistency is key for optimal results. Use continuously for at least 5 weeks to allow the collagen-building process to fully develop.

How long until I see results?

You'll notice immediate hydration and a dewy finish within the first week. After weeks 2-3, visible improvements in firmness and elasticity emerge.

The most dramatic lifting and structural renewal appears after week 5, when the full collagen building effects become apparent.

Results will develop gradually because genuine collagen rebuilding takes time.

What if I don't like it?

Real Results

What Our Customers Are Saying

I was seriously considering surgery for my drooping eyelids but decided to try this first. My lids are noticeably lifted and the skin feels much tighter. I cancelled my surgery consultation. Honestly didn't expect a serum to make this difference, but I'm genuinely impressed.

Stacey, 52, NE

I turned 50 this year and noticed my neck was where ageing really seemed to show up. I've been using this serum on both my face and neck for nearly three months and I wish I'd started using it sooner because the results are super gradual but exactly what I wanted. Very impressed!

Dianne, 50, PA

Genuinely brought some life back to my complexion. My face feels more hydrated, and it feels stronger and firmer. I didn't expect to look twenty again, but it's certainly made a noticeable difference.

Sofia, 48, AZ

My husbands gotten so sick of me spending so much money on anti-ageing products with almost nothing to show for it. But around the eight-week mark of this EGF serum even he started to notice a difference. Been part of my routine for the last 3 months now, very pleased with the progress!

Sophie, 51, IL

This has become my anti-ageing insurance policy. I'm 42 and wanted something preventative rather than waiting until everything started sagging. This absorbs so well and doesn't interfere with the rest of my skincare routine. Three months in and my skin has more bounce, my smile lines look softer too.

Carmine, TX, 42

I started using this after microneedling because I'd read about EGF and skin renewal. After a couple of months the texture across my cheeks improved, my skin looks more even. This has been able to give me what years of procedures couldn't.

Melanie, 56, CA

I've been using this for about two months and my skin just feels a bit firmer and healthier overall.

Morgan, 45, NJ

Very surprised with how natural the affect is. Nothing dramatic happened overnight, other than a little smoothing, but week by week my skin looked healthier and healthier. My pores are smaller and my cheeks feel firmer.

Emma, 47, NC

Frequently Asked

How do I use it?

We recommend using this serum twice daily - morning and evening.

Apply 2-4 drops to clean, dry skin on your face and neck, then follow up with your favourite moisturizer.

Consistency is key for optimal results. Use continuously for at least 5 weeks to allow the collagen-building process to fully develop.

Will this help with drooping or hooded eyelids?

Yes. This serum is specifically designed to address loss of eyelid elasticity and structure.

The EGF signals your skin cells to rebuild collagen and elastin, while NAD+ provides the cellular energy to execute that rebuilding.

Drooping eyelids are caused by collagen breakdown—this serum addresses that exact problem at the cellular level.

Would this help with Ozempic/ Wegovy face?

Yes. Rapid weight loss on GLP-1 medications causes your facial skin to lose volume faster than it can rebuild collagen—creating that hollow, aged appearance.

This serum accelerates collagen and elastin synthesis while providing your skin cells the energy they need to adapt to rapid body changes.

Using it during your weight loss journey helps your skin maintain structural support as your face reshapes.

Can I combine this with microneedling?

Absolutely - this is actually the ideal combination. Ue the serum on non-microneedling days, and apply it immediately after microneedling (on compromised skin).

The serum penetrates 10x better into micro-wounds and dramatically accelerates collagen rebuilding. If you're doing monthly microneedling, use this serum consistently in between sessions and immediately after for maximum results.

Is this safe for sensitive skin?

Yes.

This formula is gentle and suitable for sensitive skin. It contains soothing botanical extracts like niacinamide that calm rather than irritate.

However, if you have very reactive or compromised skin, we always recommend doing a patch test first by applying a small amount to your inner arm or behind your ear for 24 hours.

Why is the serum red?

The rich red color comes from rosehip fruit oil, one of our key botanical ingredients. This is completely natural and safe—it's the rosehip's own vibrant pigment, not artificial coloring.

The red hue actually signals the presence of powerful antioxidants (like lycopene) that protect and nourish your skin.

Don't worry about staining: the color fades completely into your skin during application and won't transfer to pillows, clothing, or leave any tint on your complexion.

What does it smell like?

This serum has a light, natural botanical scent from its blend of rosehip oil, evening primrose, hibiscus, fig, and fruit extracts. The aroma is subtle and earthy—a gentle plant-based fragrance rather than a heavy perfume. It won't overpower your senses and feels luxurious without being overly aromatic.

Can I use this with retinol?

Yes, this serum actually works great for supporting skin recovery between retinol applications.

But introduce them gradually, starting with 2-3 times per week together, then slowly increase.

Is it safe to take alongside other serums?

Yes. Apply this serum first to clean skin, then layer with other serums or moisturizers.

Wait 1–2 minutes between layers for best absorption.

How long until I see results?

You'll notice immediate hydration and a dewy finish within the first week. After weeks 2-3, visible improvements in firmness and elasticity emerge.

The most dramatic lifting and structural renewal appears after week 5, when the full collagen building effects become apparent.

Results will develop gradually because genuine collagen rebuilding takes time.

Will this work on my neck?

Yes—this serum is specifically formulated for face and neck.

The neck is often overlooked but ages quickly; this product targets neck firmness effectively.

What if I don't see results?

If you wish to receive a full refund on your order please ensure that your enquire within 90 days of receiving your order.

Customer photo review of Zentra EGF Skin Lifting Serum

After having my wisdom teeth out, I always felt like my skin lost some of its volume. I looked into fillers but wanted to try something simpler first. I've been using this serum morning and night for about eight weeks and I'm really happy with it. My skin feels more resilient, my cheeks have a bit more bounce and overall I just look less tired. It's not dramatic, but it's enough that people have commented I look well rested.

Customer photo review of Zentra EGF Skin Lifting Serum

I've been on Mounjaro for six months now and I wasn't prepared for how different my face would look. My jawline looked sharper but older at the same time. I've been using this serum twice a day and about eight weeks in I think my skin looks a lot healthier. It hasn't magically replaced the volume, but my skin feels firme and my face is much fresher. It's made a bigger difference than I expected especially from something topical.

Zentra EGF Skin Lifting Serum

Customer photo review of firming serum

Started noticing that my skin around my jawline was looking a little deflated. I've been using hyaluronic acid and niacinamide for years, but felt like I'd hit a ceiling. About eight weeks into using this serum morning and night, my skin looks noticeably firmer and smoother and my neck doesn't look as much like an old man's forehead! 😂 It's one of those products where you don't realise how much it's helping until you look at old photos.

I have sensitive skin and I can't tolerate retinol every day, so this has been perfect. No redness or peeling and it layers really well under moisturiser. Been using this for about two months my skin feels much more resilient.

I bought this after seeing people compare it to La Mer The Concentrate on tiktok. It's lightweight and sinks in immediately. I noticed the hydration straight away, but the real difference came after about four weeks, everything feels so much firmer now.

Customer photo review of Zentra EGF Skin Lifting Serum

I have EDS, so I've always known my skin needs a little extra support. I wasn't expecting a serum to completely change things, but I wanted something that focused on firmness as well as hydration. After a few months of consistent use my skin feels smoother, healthier and a bit firmer, especially around my jawline. The improvements have been gradual, but enough that I've already bought another bottle.

Zentra EGF Skin Lifting Serum

Customer photo review of Zentra EGF Skin Lifting Serum

I've always had really stretchy skin and I think I might have Ehlers-Danlos after seeing people describe similar symptoms online. But it made me look for something that focused on firmness. I've been using this for about eight weeks and my skin feels a lot better. It's become one of the few products I genuinely look forward to using every day.

Zentra EGF Skin Lifting Serum

Customer photo review of Zentra EGF Skin Lifting Serum

Wegovy has completely changed my life, but losing nearly 45lbs definitely changed my face too. My cheeks looked flatter and my face just looked gaunt. I wanted to avoid any invasive solutions so I gave this a go. After about eight weeks my skin feels firmer and my complexion looks so much healthier. It hasn't added the appearance of weight, which is what I was worried about, but it's just made my skin look much fresher and fuller.

Zentra EGF Skin Lifting Serum

Customer photo review of Zentra EGF Skin Lifting Serum

I had my wisdom teeth removed in my thirties and my cheeks have looked so much hollower since then. I tried plenty of hydrating serums but nothing really addressed what I was seeing. I've been using this for a couple of months now and my skin feels firmer, smoother and my face doesn't look quite as flat anymore. The changes have been subtle, but comparing photos I can definitely see an improvement.

Customer photo review of firming serum

I'd read that EGF takes time to work but I quickly noticed how much more comfortable my skin felt. My cheeks look fuller, my skin feels thicker somehow and even the fine lines around my eyes aren't catching the light the same way anymore. It's quickly become a permanent part of my routine.

I haven't had it long enough to see a difference.

Zentra Korean EGF Serum

So far I'm not seeing any difference.....but haven't used it very long.

Zentra Korean EGF Serum

The serum is not oily or greasy and soaks into your skin. I'm not sure if it's helping my issues yet but I'm glad that it's not getting onto my clothes or making my hands slick.

Zentra Korean EGF Serum

I can tell a significant difference in my not so droopy eyelids. A little goes a long way!

Zentra Korean EGF Serum

I have used it 2 weeks. I see improvement. Really glad

Zentra Korean EGF Serum

It has taken away the puffiness in my eye lid and haste as used the lid, somewhat.

Zentra Korean EGF Serum

I love everything about it. The texture, how soft my skin feels. It’s still too early to tell if it helps with decreasing wrinkles. Thanks

Zentra Korean EGF Serum

I really have not noticed anything different at the moment. Maybe I have not used it long enough yet, I don't know.

Zentra Korean EGF Serum

I havr been using for 3 weeks and have seen no improvement. Very disappointed.
