Indications
Malic Acid is a natural fruit acid (found in apples) used in skin-care products such as face washes, serums, toners and creams. It helps with dull or rough skin, uneven skin tone, blocked pores and mild acne marks. It is also used in small amounts in some medicines and foods to adjust acidity and flavour.
How It Works
Malic Acid is an alpha hydroxy acid (AHA). On the skin it loosens the bonds between dead cells on the surface so they shed more easily. This gentle exfoliation makes skin smoother and brighter, helps keep pores clear, and can help other skin-care ingredients work better. It is milder than Glycolic Acid because its molecule is larger.
Dosage and Administration
Use as directed on the product label. Leave-on products are usually applied once a day, often at night, to clean dry skin; start every other day to let the skin get used to it. Wash-off products are massaged gently and rinsed. Avoid the eyes, lips and broken skin. Apply sunscreen every morning while using it.
Interactions
Using it together with other exfoliating acids (such as Glycolic Acid or Salicylic Acid), Benzoyl Peroxide, Tretinoin or other retinoids, or scrubs can increase redness, stinging and peeling. If you use these, apply them at different times or on different days, or ask a pharmacist or dermatologist.
Contraindications
- Allergy or known sensitivity to Malic Acid or any ingredient of the product.
- Broken, sunburnt, infected or severely inflamed skin.
Side Effects
Mild tingling, stinging, redness, dryness or flaking can occur, especially at the start. It makes skin more sensitive to sunlight, increasing the risk of sunburn. Darker skin types may get dark patches if irritation occurs.
Stop using it and get urgent medical help if you have swelling of the face, lips or eyes, blistering, severe burning, or difficulty breathing.
Pregnancy and Lactation
Low-strength cosmetic products containing Malic Acid are generally considered acceptable during pregnancy and breastfeeding because very little is absorbed. Avoid strong peels and check with your doctor if unsure.
Precautions and Warnings
- Always do a patch test on a small area first.
- Use broad-spectrum sunscreen daily and for a week after stopping.
- Do not use before waxing or on freshly shaved skin.
- Professional peels with high strength should only be done by a trained practitioner.
Overdose
Using too much or too often causes irritation, redness and peeling; stop until the skin settles. If swallowed in large amounts, rinse the mouth and contact a doctor.
