Macadamia Oil

Macadamia oil is very high in omega 6 and omega 9 which are very nourishing and will help to maintain hydration and relieve dry skin. Macadamia has anti-inflammatory properties so is a fantastic ingredient to treat tender, inflamed, or irritated skin.


Magnesium is a mineral that is vital for so many reactions in the body. It helps to reduce cortisol levels - the hormone responsible for stress, which in turn helps to minimise inflammation, sensitivity, breakouts and lack of sleep. It can be applied directly onto the skin or taken as an oral supplement.

Malic Acid

Malic acid is sourced from apples and is an alpha hydroxy acid. Like all alpha-hydroxy acids, it does have exfoliating properties but on top of this, it also aids hydration and has antioxidant properties providing protection.

Mandelic Acid

Mandelic acid is an alpha hydroxy acid sourced from almonds. The interesting feature of this particular acid is the fact that even though it is AHA it can behave like BHA. It is suitable for most skin types and can be used all year round.

It has exfoliating properties, encouraging cell turnover and has antimicrobial properties which can help reduce acne-causing bacteria so it is specifically helpful with acne, congestion and pigmented skin, therefore, works great for post-summer skin that need glow and evening out the skin tone.

Manuka Oil

Manuka oil, sourced from the manuka flower, has been used for centuries by the Maori tribe for wound healing. It is a potent antibacterial agent and has also been shown to assist in wound healing.

Marula Oil

Marula oil is a plant-derived oil. It has high levels of vitamin C and E, omega 3 fatty acids as well as being antimicrobial. It is sourced from the marula plant which is indigenous to Southern and Western Africa.

Meadowfoam Oil

Meadowfoam seed oil has a similar composition to sebum. This means it can effectively moisturise the skin as well as control oil production in more oily skin types. It is also rich in antioxidants, protecting the skin from free radical damage. 

Mechanical Exfoliation

Mechanical exfoliation is the process of removing dead skin cells through physical action. Examples of mechanical exfoliation include scrubs, microfibre cloths, or more intensive forms such as microdermabrasion.

Medical Needling

Medical needling, also known as Collagen Induction Therapy (CIT), is a safe advanced technique to encourage collagen production and cell regeneration which contributes to improving skin ageing, textural imperfections and irregularities in the skin’s appearance. The treatment aim is to create a controlled trauma to the dermis of the skin by penetrating using fine sterile needles generating a number of microchannels. The natural skin response of wound healing leads to tissue remodelling which creates a thickening in the skin which helps to reduce the appearance of fine lines and wrinkles, pore refinement, uneven skin tone and superficial scarring. The microchannels created by the treatment also provide an absorption route to deliver active ingredients into the deeper layers of the skin allowing us to maximise their function and achieve superior results. Medical needling requires moderate downtime (up to 3 days) which means your post-procedure results are quickly achieved. Another great advantage of medical needling is the treatment is safe and effective in every skin type but should be carried out by an experienced practitioner. To ensure we maximise your comfort during the procedure a topical anaesthetic may be applied by your therapist. Medical needling is a form of skin remodelling.


Melasma is a form of hyperpigmentation that is closely related to hormones. It presents itself as a symmetrical pattern of brown patches often on the forehead, nose, cheeks, upper lip and chin. It can occur during pregnancy (known as pregnancy mask) but can also develop whilst breastfeeding, taking hormonal contraceptives, HRT, or even during ovulation. Melasma is exacerbated by heat and its for this reason that it cannot be treated by many laser led treatments such as IPL.


Uses professional aesthetic machines to allow the faster and deeper penetration of active substances in the dermis. It uniquely opens temporary channels in the dermis, therefore allowing the passing of active ingredients with a low molecular weight. Mesoporation is used as an alternative to mesotherapy, which involves the use of needles - therefore giving those with a fear of needles an opportunity to achieve better results. Mesoporation provides a plethora of benefits to the skin. With the use of low molecular weight active ingredients to specifically target certain conditions, it improves skin tone, diminishes wrinkles and improves sagging skin, gives great anti-ageing effects, deeply hydrates and has a lifting effect.


Microdermabrasion uses fine crystal and vacuum to mechanically exfoliate the skin. It works by using tiny crystals to remove dead skin cells and other impurities. By removing the top layer of skin, it triggers an injury response, encouraging your skin to renew faster. At Pfeffer Sal, we don’t personally believe in microdermabrasion as we feel it is too harsh on the skin and prefer chemical or laser resurfacing techniques. 


Milia are little keratin and fat deposits trapped under the skin membrane. They have no channel to leave the skin so appear as while bumps on the surface of the skin. They cannot be squeezed out and must be removed through gentle ongoing exfoliation or lanced by a skincare professional.


The microbiome is the genetic material of all the microbes - bacteria, fungi, protozoa and viruses - that live on and inside the human body. The microbiome is essential for human development, immunity and nutrition. 

Mineral Oil

On the one hand, Mineral Oil is lightweight, cheap, safe for most skin types and typically doesn’t cause allergic reactions. What’s more, it is an occlusive agent meaning it won’t allow water to leave the skin and therefore stops dehydration in its tracks. Hello beautifully moisturised complexion! But on the other hand, despite being labelled ‘natural’ because it comes from the earth, the way it is extracted, processed and refined causes concern for the environment. These oils are extracted as part of the petro-chemical industry, they are non-renewable and add to the exploitation of the earth for fossil fuel. In short, by the time mineral oils used for skincare have been extensively purified, there isn’t much of their ‘natural’ origin left and the purifying process negatively impacts our planet. Here at Pfeffer Sal we don’t believe Mineral Oils are the be-all and end-all for fabulous skin so we don’t use it in our products - there are plenty of environmentally-friendly alternatives out there.

Mineral SPF

Mineral based sunscreens work by reflecting the sunlight away from the skin. The active ingredient in mineral sunscreens are zinc or titanium oxide and the tiny particles act as a shield on the skin, blocking the UV rays before they are able to penetrate the skin and cause photodamage. As zinc oxide is also an anti inflammatory,, mineral sunscreens are usually more gentle than chemical based sunscreens and therefore more suited for sensitive skin.

Modified Jessner

Modified Jessner is a combined peel formulated with a precise combination of chemical exfoliants including salicylic acid, lactic acid and citric acid. It is safe for all skin types. This synergistic combination of acids means it’s perfect the most common skin concerns of skin ageing, expression lines, loss of firmness and the improvement of mild pigmented areas. This is why it is perfect as part of our glow and go treatment, getting you ready for any occasion.


A mole occurs when a collection of melanocytes (pigment producing cells) grow in a tight knit group rather than evenly throughout the skin. Moles appear as small darker areas in the skin and can be flat or slightly raised above the skin. Whilst the majority of moles are harmless, if there are any shape or colour changes it’s important to see a doctor or specialist to check they are benign.
