Magnesium FAQ

Magnesium FAQ

What is topical magnesium?

Topical magnesium is magnesium applied directly to the skin rather than taken as an oral supplement. At TerraSana Farms, we offer magnesium in three forms: magnesium oil spray, magnesium lotion, and convenient roll-ons.

People commonly incorporate topical magnesium into their evening routine, after physical activity, or anytime they want a simple way to add magnesium to their self-care routine.

What do people use magnesium for?

Magnesium plays an important role in normal muscle and nerve function and many other processes in the body. Our customers commonly reach for topical magnesium as part of routines for relaxation, bedtime, tired or overworked muscles, restless-feeling legs, and everyday muscle tension.

Because everyone's body and needs are different, we recommend starting slowly and finding the form and routine that works best for you.

Which type of magnesium should I start with?

If you've never used topical magnesium before, magnesium lotion is often the easiest place to start. It is gentle and easy to control, and the lotion base makes it simple to massage into the skin.

If you prefer something quick and lightweight, try the magnesium oil spray. For small, targeted areas or something you can easily carry with you, the roll-on is a great option.

There isn't one form that is best for everyone. Many customers eventually keep more than one form on hand for different situations.

Should I start with scented or unscented magnesium?

If you are new to topical magnesium or sensitive to fragrances and essential oils, Unscented is an excellent place to start.

If you're looking for something specifically for your evening routine, Quiet Nights is another good starting point. Its lavender and chamomile aroma is soft and calming without requiring a more complex scent blend.

You don't need to start with our strongest or most complex scent. Start simple, see how your skin responds, and then explore the other blends if you'd like.

What scents do you offer?

Our magnesium line currently includes:

Unscented – No added essential oils. A simple option for sensitive noses, children, or anyone who prefers fragrance-free products.

Quiet Nights – Lavender and chamomile. Our bedtime-focused blend and a popular choice for winding down in the evening.

Moonlit Path – Jasmine, rose, lavender, and sandalwood. A soft floral blend with warm, grounding notes.

London Fog – Pine, bergamot, and lavender. Fresh, outdoorsy, and clean with a touch of lavender.

Smoke & Leather – Cedarwood, bergamot, patchouli, lavender, and ylang-ylang. A deeper, earthy blend for those who prefer less floral scents.

Twilight Rain – Lavender, pine, clove, vanilla, cinnamon, and ylang-ylang. A warm, complex blend with both relaxing and spicy notes.

The magnesium itself is the foundation of each product. The scent blends simply allow you to choose the aroma and experience that best fits your preference.

Can children use topical magnesium?

Topical magnesium can be incorporated into a child's bedtime routine, but we recommend taking a more conservative approach with children.

For children, magnesium lotion is our preferred form because it is easy to apply a small, controlled amount and tends to be gentler on the skin than magnesium oil spray.

For bedtime, Quiet Nights lotion is our preferred scented option because of its lavender and chamomile blend. Unscented lotion is another excellent choice, particularly for younger children or children with sensitive skin.

Start with a small amount and patch test first. Avoid the face, broken or irritated skin, and keep the product out of children's reach. Parents should consult their child's healthcare professional before use if the child is very young, has a medical condition, takes medication, or has known sensitivities.

How should I use magnesium at bedtime?

Apply your magnesium approximately 20–30 minutes before bed as part of your normal nighttime routine.

With lotion, massage a small amount into areas such as the legs, feet, shoulders, or other areas where you prefer to use it.

If you're new to topical magnesium, start with a small amount rather than assuming that more is better. You can gradually adjust based on your own routine and skin tolerance.

Why does magnesium oil sometimes sting or tingle?

Some people notice a tingling, itching, or mildly stinging sensation when they first use magnesium oil. This is one reason we often recommend lotion for first-time users or people with sensitive skin.

Do not apply magnesium oil immediately after shaving or to broken, freshly irritated, or damaged skin, because it can sting considerably more.

If the sensation is uncomfortable, wash the product off and try the lotion instead.

Where should I apply topical magnesium?

Common application areas include the:

  • Feet

  • Calves and legs

  • Shoulders

  • Neck

  • Back

  • Arms

  • Other areas of everyday muscle tension

Avoid the eyes, face, mucous membranes, and broken or irritated skin.

Do I need to wash magnesium off?

Not necessarily. If you're comfortable leaving it on your skin, you can.

Some people prefer to wash magnesium oil off after it has been on the skin for a while because the mineral salts can leave a slightly tacky or dry feeling. Lotion is generally more comfortable to leave on the skin.

What's the difference between the spray, lotion, and roll-on?

Magnesium Oil Spray – Great for larger areas and quick application. It has direct skin contact with the magnesium solution but may tingle more than lotion.

Magnesium Lotion – Our gentlest and most versatile option. It's especially good for bedtime routines, dry or sensitive skin, first-time magnesium users, and children.

Magnesium Roll-On – Convenient for targeted application and easy to keep in a purse, desk, nightstand, gym bag, or travel bag.

You don't have to choose one permanently. Each form serves a slightly different purpose.

How often can I use topical magnesium?

Many people use topical magnesium once daily, particularly in the evening, while others use it as needed.

If you're new to magnesium, start with a smaller amount and give yourself time to see how your skin responds before increasing how much or how often you use it.

Can I use topical magnesium if I take medications or magnesium supplements?

Topical magnesium shouldn't be treated as a substitute for medical care or prescribed treatment.

If you have kidney disease, a significant medical condition, are pregnant or breastfeeding, take prescription medications, or already take magnesium supplements, talk with your healthcare professional before adding another magnesium product to your routine.

Which magnesium product is right for me?

If you're still unsure, this is a simple place to start:

New to magnesium: Unscented Lotion
Bedtime routine: Quiet Nights Lotion
Sensitive skin or sensitive to scents: Unscented Lotion
For children: Unscented or Quiet Nights Lotion
Larger areas or after physical activity: Magnesium Oil Spray
Targeted or on-the-go use: Magnesium Roll-On
