Why We Created a Slow-Release Magnesium Sleep Gel - and Who It’s For

"What we apply to our skin doesn’t stay on the surface - it travels in." - Dr. Philippa Darbre, Professor of Oncology, University of Reading
At Surmanti, we believe your skin is not just a barrier - it’s a powerful pathway. That’s why our sleep range is built around transdermal (topical) absorption: delivering minerals and botanicals directly through the skin to support rest, calm, and recovery.
While our Magnesium Sleep Support Spray works quickly and powerfully, some of our customers needed something gentler. For children, older adults, immune-compromised individuals, or anyone with skin sensitivity or tingling - the spray was sometimes too fast, too intense.
That’s why we created the Surmanti Magnesium Sleep Support Gel - a slow-release formula that absorbs gently over time, making it perfect for those who need calm that builds gradually and lasts all night.
Topical Absorption: Backed by Science
Your skin is the body’s largest organ, and it's highly absorbent - especially on thinner areas like the feet, legs, and wrists. When applied topically, magnesium can pass through the skin barrier, enter circulation, and begin supporting the nervous system within minutes.
Studies show that magnesium applied to the skin can help replenish cellular magnesium stores while avoiding gastrointestinal side effects associated with oral supplements [1]. This is especially beneficial for people with sensitive stomachs, absorption issues, or high stress levels.
Dr. Philippa Darbre’s research further confirms that compounds applied to the skin can penetrate and enter the bloodstream within 20minutes [2] - reinforcing why clean, conscious ingredients matter.
Why Slow-Release Matters for Children, the Elderly, and the Immune-Compromised
Young, aging, and immune-sensitive bodies tend to respond more intensely to fast-absorbing or highly concentrated formulas. A sudden influx of magnesium or actives may cause sensations like tingling, restlessness, or discomfort.
A slow-release gel like ours is ideal because:
  • Children (4+) have thinner, more reactive skin. Gentle absorption helps avoid overstimulation.
  • Older adults often have drier skin and reduced barrier function. The gel hydrates while working slowly and comfortably.
  • Immune-compromised individuals or those on medications may react to fast absorption. This formula is balanced, soothing, and predictable.
With natural thickeners and skin-loving lipids, the gel stays on the skin longer, allowing ingredients to absorb gradually while hydrating and nourishing the skin.
A Smarter Alternative to Melatonin
Unlike many sleep products, we never use synthetic melatonin - and there’s a reason.
While melatonin is a hormone your body naturally produces, synthetic melatonin (common in gummies and pills) may:
  • Disrupt natural sleep-wake cycles [3]
  • Create grogginess or mood swings the next day
  • Be unsuitable for children, teens, or long-term use
  • Interfere with hormonal balance [4]
Our formula supports your body’s own rhythm, helping you unwind without hormonal manipulation or side effects.
Why It Works  
Surmanti’s Sleep Support Gel is made with 99% natural origin ingredients and 1% plant-based, nature-identical actives - carefully selected for their effectiveness, purity, and compatibility with sensitive skin.
Topical Magnesium (Chloride + Sulfate)
Bypasses digestion to deliver minerals directly through the skin.
  • Magnesium Chloride – Highly bioavailable; supports nervous system regulation
  • Magnesium Sulfate (Epsom Salt) – Traditionally used to ease muscle tension and promote relaxation [5]
Valerian, Passionflower & Hops
Botanicals traditionally used in Western herbal medicine to support sleep and ease nervous tension [6]
MSM (Methylsulfonylmethane)
A bioavailable sulphur compound that enhances absorption and reduces skin sensitivity
Black Pepper Extract & Essential Oil
  • Piperine Extract enhances bioavailability by helping actives penetrate the skin
  • Essential Oil supports circulation and provides gentle warming to aid delivery
Lavender, Frankincense & Cedarwood Oils
Used in aromatherapy to reduce mental chatter and support pre-sleep relaxation
Oat Lipids & CCT (Caprylic/Capric Triglyceride)
Hydrate, nourish, and protect the skin barrier while promoting a smooth, non-greasy feel
Why You Need to Use It Consistently for 2–4 Weeks
Like anything natural, the effects build with time. Magnesium works best when replenished gradually, not all at once. And the body’s nervous system often takes time to recalibrate — especially if you're dealing with long-term stress, disrupted sleep, or physical tension.
That’s why we recommend:
  • Using the gel nightly, ideally 60 minutes before bed
  • Applying after a warm bath or hot shower, when pores are open and absorption is enhanced
  • Targeting clean skin on areas like the lower legs and soles of the feet, where capillary flow and pore density are highest
  • Allowing 2–4 weeks of consistent use for noticeable, lasting improvements in sleep, mood, and muscle relaxation
You’re not sedating your body — you’re retraining it to unwind naturally, gently, and consistently.
Common Questions We Hear
Does it work right away?
Some users feel relaxed after the first use, but it’s not a sedative. It works gradually to help your body unwind and fall asleep naturally.
Can I use it on my child?
Yes - the gel is suitable for children aged 4+. Apply a small amount to feet or lower legs, and monitor for any skin sensitivity.
Does it sting?
No. Unlike some sprays, this gel is non-stinging and well tolerated thanks to MSM, oat lipids, and gentle absorption.
Is it safe during pregnancy or breastfeeding?
As with any topical product, we recommend checking with your healthcare provider before use.
