FAQS

Jumbo Neck Firming Serum

What's different about this serum?

This limited edition Neck Firming Serum comes in a jumbo 100ml size. It is over three times larger than our standard bottle and features an exclusive print on the box and label. Don’t worry, it’s the exact same formula you already know and love.

Does Boost Lab's Neck Firming Serum really work?

Boost Lab’s award-winning formulas have changed the skin of thousands of women, especially those noticing crepe-like, sagging skin. After countless reviews sharing that our Edelweiss Neck Firming Serum is one of the best skin firming serums for the neck, we’re proud to have created a valuable addition to the skincare routines of everyday women just like you. 

What is the best non-surgical neck tightening treatment?

There are proven non-surgical treatments to improve the elasticity and tightness of skin in and around the neck area. Here are a few ideas:

  • Update your skincare routine: It might have been a while since you reviewed the products and stages of your daily routine. There’s been huge advancement in skincare in the last decade, so now’s the perfect time to make sure you’ve got the right products for your stage in life. Take our skin quiz as a first step.
  • Make a few small lifestyle adjustments: Taking better care of your overall health is often reflected in your skin. Diet and exercise are a good place to start. Plus, when you’re out in the sun, make sure you’re protected. Our high-quality SPF serum can help, along with a hat and the right clothing. 
  • Utilise firming neck serums: For long term support, serums like ours can visibly reduce wrinkles, crepe-like textures and tighten the delicate skin of the neck. 

If you’re concerned about your neck area or notice changes that don’t look or feel right, consult a medical professional or dermatologist for extra support. 

Why does neck skin sag?

There are a number of reasons why neck skin changes in texture and appearance. As you age, your skin naturally loses tightness due to lower collagen and elastin production. Similarly, weaker neck muscles or poor posture from working at a computer can also have a big impact. Combine these factors with other lifestyle changes – like losing weight rapidly or shifting your habits – and your skin might not continue to look the same over time. 

Neck and face skin are particularly challenging as they tend to get a lot of sun exposure and varied movements. But most typically, sagging neck skin is a sign of ageing. Which is why we’ve developed a range of serums and creams to help you manage changes in your skin.

    Boost Lab Neck Firming Serum

    I have tried quite a few neck firming creams - alas none have ever given me much improvement other than nice soft neck but with Boost Lab I have only been using it for about 3 weeks and I can see a difference.

    I'm not of an age where I expect miracles but it's great to see some change and this I have seen.

    I will be purchasing more of this Serum.

    Great product

    I was a little apprehensive using this as with many products their claims of what they do aren't as good as they say but I have to say that this stuff really does work. I've been using it for almost a month now & have seen a massive difference in my neck area. I woll definitely be purchasing a 2nd bottle & my mom has also now made a purchase after seeing my results

    Improvement in texture of skin

    I must say although the difference may look small to minimal to some to me it has most definitely improved the texture of my skin & the crappiness is really beginning to improve too …

    I will continue use & look forward to the continued results 🥰👏🏻

    I'm a sceptical Sally but this works

    I was sceptical but desperate when I saw an add for this online, I'd lost a lot of weight from my face quite quickly, but this has made a difference already, and I'm not even finished the bottle yet. Feels nice, is really quickly absorbed, and doesn't feel sticky. I'm a fan!
