Frequently Asked Questions

What is Peptide Serum Concentrate?

Peptide Serum Concentrate is a lightweight nail and cuticle serum formulated to deliver an intensive dose of hydration and repair to dry, brittle, or damaged nails and cuticles. Unlike traditional oils or creams, this fast-absorbing gel-serum features 12% active ingredients—including Cranberry Peptides, Aloe, Glycerin, D-Panthenol, and antioxidant-rich botanical extracts—to help strengthen, moisturize, and visibly rejuvenate nails and cuticles.

With daily use, it helps:
- Deeply hydrate dry nails and cuticles
- Help reduce peeling and brittleness
- Soothe stressed, dehydrated cuticles
- Support stronger, healthier-looking nails
- Encourage healthier nail regrowth

Think of it as a daily treatment serum for your nails—similar to how a facial serum delivers concentrated care for your skin.

How is Peptide Serum Concentrate different from cuticle oil?

Both products nourish the nails and cuticles, but they work differently. Peptide Serum Concentrate is a lightweight, water-based gel-serum formulated with concentrated active ingredients that absorb quickly to deliver targeted hydration and repair. Nourishing Cuticle Oil is an oil-based treatment that helps seal in moisture and soften dry cuticles.

For very dry or damaged nails, many people enjoy using the serum first, then following with cuticle oil to help lock in moisture.

What do peptides do for nails?

Peptides are short chains of amino acids that help support the condition of the nail and surrounding cuticle. Peptide Serum Concentrate features Cranberry Peptides, which help strengthen weak, damaged nails while supporting healthier-looking cuticles. Combined with hydrating ingredients like Aloe, Glycerin, and D-Panthenol, the formula helps improve the overall appearance and resilience of nails over time.
Together, these ingredients help:
- Support stronger-looking nails
- Reduce the appearance of brittleness
- Improve hydration
- Soothe stressed cuticles
- Promote healthier-looking nail growth

Can I use Peptide Serum Concentrate with nail polish or gel manicures?

Yes. Peptide Serum Concentrate can be used whether your nails are bare or polished. On bare nails, apply the serum directly to the nail plate and cuticles for intensive care. If you're wearing traditional polish or a gel manicure, simply apply it around the cuticles and massage it into the surrounding skin to help replenish moisture without affecting your manicure.
It's especially beneficial:
- After gel or acrylic removal
- Between manicures
- During dry winter months
- After frequent handwashing
- Anytime nails or cuticles feel dry or stressed

Is Peptide Serum Concentrate good for nails after gel removal?

Yes. Peptide Serum Concentrate is an excellent choice for nails recovering after gel polish, acrylics, or frequent manicures. The lightweight formula was specifically developed to help replenish moisture, soothe stressed cuticles, and support brittle or weakened nails during the recovery process.
Following gel removal, it helps:
- Restore hydration
- Calm dry, stressed cuticles
- Help reduce peeling and brittleness
- Support healthier-looking nail regrowth
- Improve the overall appearance of natural nails
For best results, use it daily as part of your nail recovery routine.

Does my Peptide Serum Concentrate have less than it is supposed to? There is noticeable empty space at the top of the bottle.

Great question, and good news — you're actually getting more than what's promised! Every bottle is labeled at 10mL, but we overfill each one to approximately 11mL, so that extra room at the top allows room for a bit of bonus product. As for the empty space itself, that's by design too: the extra space prevents pressure build-up so none of your serum is lost to leaks or squirts out when you remove the cap. So really, that gap at the top is working in your favor on two fronts. Enjoy every last drop!

Is Peptide Serum Concentrate vegan and clean?

Yes. Peptide Serum Concentrate is certified vegan, cruelty-free, gluten-free, and formulated to LONDONTOWN's clean formulation standards. Its lightweight formula combines 12% active ingredients with Cranberry Peptides, Aloe, Glycerin, and D-Panthenol to deliver intensive hydration and strengthening support without a heavy or greasy feel.
Whether you're restoring nails after a manicure or maintaining healthy-looking cuticles every day, Peptide Serum Concentrate delivers concentrated care in a fast-absorbing formula designed for modern nail wellness.

I can't figure out how to get the product out of my Peptid Serum Concentrate. What is the proper way to dispense?

Once you know the trick, it's a breeze! Just pull the clear cap that covers the nozzle of the bottle straight up (no twisting necessary) to remove it, then tint the bottle and aim that pointed tip right at your cuticle. Give the soft base a gentle press until one perfect drop is released, repeat for each nail, then massage it in. That's it, happy nails ahead!

Great priduct
I used this for 25 days straight and the results were awesome. Unfortunately, the bottle is too small and I ran out. Highly recommend. But would prefer a different packaging and a bigger bottle, more product. It’s a bit pricey for such a small bottle.

So far it's been nice, but
It is very moisturizing and I do enjoy really enjoy the way it smells. I like the product and feel it works well in terms of that. I'm still testing it. That being said.....
A big con though is the application. This product is expensive so not being able to control well how much comes out is wasteful. Also, just opening it up you have to be careful not to push the bottom or the serum will come out, same with closing it.

We’re so glad you’re enjoying the moisturizing feel and scent so far! We also really appreciate your feedback about the application and the difficulty controlling how much serum is dispensed. That’s an important part of the overall experience, especially with a concentrated formula where a little goes a long way. Our Customer Service team will reach out directly to help make the application easier and ensure the rest of your experience with the serum is a positive one.

Outstanding!
I'm almost 75, and my two thumb nails had lots of ridges in them. I decided to give this serum a try, and the results are tremendous! The first bottle almost left my nails completely healed, so I ordered two more to finish the job.
