How to Treat a Foot Blister with Traditional Home Remedies

Blisters form when the skin is subjected to repeated friction or localised pressure. Imagine the outer layer of the skin sliding slightly over the layer beneath: this movement creates a small tear between them, and to protect the weakened tissue, the body fills the space with a clear fluid called serum. This fluid acts like a natural cushion, protecting the area and promoting skin repair. The most common areas affected are therefore the feet – particularly when new shoes rub against the heel or toes – and the hands, especially among sportspeople or musicians who regularly handle tools or instruments. Skin is more prone to blisters when it is thin, damp, or exposed to heat, as these factors increase friction.

Good to know: A blister is a sign that the skin is protecting itself from mechanical stress; in other words, reduce friction and allow time for the area to heal.

Blisters, although harmless, can quickly become uncomfortable, especially on the feet. Taking the right steps as soon as they appear helps to minimise pain, protect the skin and promote optimal healing. Discover our tips: 

Protect the Area: Cover the blister with a plaster or soft dressing to minimise friction and prevent it from bursting accidentally. The aim is to create a physical barrier whilst allowing the skin to breathe slightly.

Do not Pierce the Blister: Even if it seems uncomfortable or painful, the fluid inside forms a natural barrier against bacteria and promotes healing. Piercing the blister increases the risk of infection and can slow healing.

Wash Gently: Clean the area with lukewarm water and mild soap, without rubbing. This removes impurities whilst being gentle on the delicate skin and minimising irritation.

Let the Skin Breathe: Whenever possible, remove the plaster for a few moments to allow air to circulate and the skin to dry naturally. This short break aids healing and prevents moisture build-up, which could encourage bacteria.

Reduce Pressure and Friction: Adjust your shoes, socks or kit so as not to aggravate the blister. Specialised pads or plasters can help distribute pressure and relieve pain.

Monitor Its Progress: Check the blister every day. Significant redness, marked swelling, or unusual discharge are signs to watch for and, if needed, consult a healthcare professional.

Prioritise Comfort: Wear looser-fitting shoes, clothing, and socks made from natural fibres to minimise friction, especially during prolonged activities such as walking or playing sport.

Natural, gentle, and effective ways to relieve blister pain on your foot exist. Follow our guide to prevent blisters from forming, or to get back to feeling comfortable if a blister has already appeared:

Soothing Foot Baths

After a tough day on your feet, treat yourself to a lukewarm foot bath using one of the following options, depending on your preference:

Bicarbonate of Soda Foot Soak: Pour 2 tablespoons of bicarbonate of soda into a basin of lukewarm water. This mixture cools overheated feet, soothes redness from rubbing, and helps cleanse areas that are already sensitive or prone to blisters.

Deodorised (Wild) Shea Butter

To prevent blisters, apply a small amount of shea butter to friction-prone areas before a hike or long run. The butter forms a protective film and helps prevent blisters.

Essential oils are powerful natural concentrates. Please refer carefully to the intended uses and precautions for use on each product information sheet. Store them in a suitable glass bottle, away from light and air.

Keep out of reach of children. Do not use on pregnant or breastfeeding women, or on children under 6 years of age. Avoid contact with the eyes and mucous membranes. Please refer to the General Safety Information Sheet for Essential Oils as well as the specific information sheet for each essential oil.

Popping a blister is generally not recommended as it can increase the risk of infection and slow down the healing process. Allow the skin to cover the area naturally and protect it with a suitable plaster to minimise friction. If the blister becomes very uncomfortable or is likely to burst on its own, consult a healthcare professional or ask your pharmacist for advice.
