FAQs

Our Frequently Asked Questions from our customers and community!

Which product is more hydrating: your Complete Serum or Green Oil? What is the difference?

Our Complete Serum has a water-based formula that contains powerful hydrating agents, while our Green Oil is made from botanical oils that deeply nourish the nail. For maximum hydration, we recommend our Complete Serum. To deeply nourish, use our Green Oil.

When should I apply Green Oil/Complete Serum?

Green Oil and Complete Serum can be applied to manicured nails and the surrounding skin at any time of day to nourish your nails and boost hydration. First, apply the Complete Serum to bare nails, then lock in the hydration with a drop of Green Oil before massaging it in to help it penetrate. If you're taking a break from nail polish, wait until your Sunshine Top Coat is dry and then apply a drop of Green Oil to the base of each nail, massaging it into the skin to help it penetrate.

Can Green Oil/Complete Serum be rinsed off?

Green Oil and Complete Serum cannot be rinsed off. These nourishing, moisturising products penetrate the surface of the nail and surrounding skin to work deep within.

Should I leave Green Oil/Complete Serum on to let it work?

Green Oil and Complete Serum need to be massaged in to penetrate the surface of the nail and surrounding skin. These products cannot be rinsed off.

What are the benefits of using a nail serum?

Nail serums offer multiple benefits that directly contribute to the health and appearance of your nails. They provide intensive nourishment to both the nails and cuticles, targeting common concerns like weakness, brittleness, and discolouration. Enriched with key ingredients such as biotin, keratin, and vitamin B complex, nail serums strengthen nails from within, improving their structure and growth.

Regular use of a nail serum helps to restore moisture, protect against environmental damage, and promote smoother, more even nail surfaces. This makes it a vital addition to any nail care routine, especially for those with damaged or compromised nails.

How often should I apply nail serum for best results?

For optimal results, nail serum should be applied daily. Apply it directly to clean nails and massage it into the nail plate and cuticles. Using the serum consistently helps improve nail health over time, ensuring that the nourishing ingredients are absorbed fully.

If you’re aiming to repair weak or damaged nails, you may want to apply the serum twice daily, especially during the first few weeks of use. This increased frequency accelerates the repair process, giving your nails the best chance for rejuvenation and growth.

Can a nail serum repair damaged nails?

Yes, nail serums can effectively repair damaged nails. They are formulated to target nail damage at its source, working to improve strength, hydration, and flexibility. Ingredients like methionine, keratin, and panthenol help restore the nail’s structure by promoting regeneration and improving its overall health.

While nail serums may not provide immediate results, consistent use over several weeks can visibly improve nail texture, smoothness, and strength. This makes them an ideal solution for nails that are brittle, split, or affected by environmental factors like dryness or harsh chemicals.
