Indications
Avobenzone is a sunscreen ingredient found in creams, lotions and gels. It is used to protect the skin from the sun’s ultraviolet A (UVA) rays, which cause tanning, early skin ageing, wrinkles and dark spots and add to the risk of skin cancer. It is usually combined with other filters that block ultraviolet B (UVB) rays, which cause sunburn, to give broad-spectrum protection. It may also help people whose skin conditions, such as melasma, worsen with sunlight.
How It Works
Avobenzone is a chemical (organic) UV filter. Its molecules absorb UVA light energy before it can reach and damage the deeper layers of the skin, and release the energy as a tiny amount of harmless heat. On its own it can break down in sunlight, so products usually add stabilising ingredients to keep it working longer.
Dosage and Administration
Apply generously and evenly to all exposed skin about 15 to 20 minutes before going out in the sun. Reapply at least every 2 hours, and straight after swimming, heavy sweating or towel drying. Use as directed on the label. For children under 6 months, keep them out of direct sun and ask a doctor before using any sunscreen. For external use only.
Interactions
No important interactions with medicines are known. Some medicines, such as certain antibiotics (Doxycycline), acne medicines and diuretics, make the skin more sensitive to sunlight, so good sun protection is especially important while taking them.
Contraindications
Do not use if you are allergic to Avobenzone or any other ingredient in the product. Do not apply to broken, infected or badly irritated skin.
Side Effects
Most people have no problems. Some may notice stinging, redness, itching or a rash, especially around the eyes or on sensitive skin. Allergic or light-triggered skin reactions are uncommon. Avobenzone can stain some fabrics yellow, especially in water with iron.
Stop using the product and get urgent medical help if you develop swelling of the face, lips or eyes, difficulty breathing, or a severe, spreading rash with blistering.
Pregnancy and Lactation
Sunscreens containing Avobenzone are commonly used during pregnancy and breastfeeding. Avoid applying it to the nipple area just before feeding. If unsure, ask your doctor or pharmacist.
Precautions and Warnings
Sunscreen is only one part of sun protection: also seek shade between 10 am and 4 pm, and wear a hat, sunglasses and covering clothes. Keep it out of the eyes; if it gets in, rinse well with water. Test on a small area first if you have sensitive skin. Do not use after the expiry date, as protection may be reduced.
Overdose
Using a lot on the skin is not harmful. If swallowed by accident, rinse the mouth and contact a doctor or pharmacist for advice.
Therapeutic Class
