Stop Spraying Perfume on Your Neck! The Hidden Cause of Sun Spots & Hyperpigmentation

If you’ve noticed stubborn dark patches appearing along the sides of your neck or across your chest, you might assume it's just standard sun damage or natural aging. But if you religiously wear perfume or use heavily scented body lotions before heading outdoors, your favourite signature scent might actually be the culprit.

​This phenomenon is known in clinical dermatology as Berloque Dermatitis.

​How Fragrance + Sunlight = Dark Spots

​Many perfumes, body mists, and scented moisturisers contain photosensitising ingredients. The biggest offenders are natural citrus extracts (like bergamot, grapefruit, and lemon oils) and specific aromatic compounds.

​When these ingredients are sprayed directly onto delicate skin and then exposed to ultraviolet (UV) radiation from the sun, a chemical reaction occurs:

​The Phototoxic Reaction: Sunlight activates the fragrance molecules, causing a localized cellular reaction on the skin's surface.

​Inflammatory Trigger: This reaction causes subtle, sometimes invisible inflammation and cell damage.

​Melanin Overdrive: To protect itself, your skin responds to this damage by producing an surge of melanin. As the initial reaction heals, it leaves behind persistent, dark brown discolouration.

​Because people traditionally spray perfume on their pulse points—specifically the sides of the neck and the décolletage—these UV-exposed areas are the most frequently damaged.

​How to Protect Your Skin Without Giving Up Fragrance

​You don’t have to throw away your favourite perfumes, but you do need to change how you apply them during sunny weather:

​Spray Your Clothes, Not Your Skin: Apply your fragrance to your clothing, hair, or lower body areas that will remain covered by clothes. Never spray directly onto the neck, chest, or wrists if those areas will see daylight.

​Choose Fragrance-Free SPF 50: Your neck and chest require daily, broad-spectrum sun protection. Opt for clinical, fragrance-free SPF formulations that protect the skin barrier without introducing reactive scent compounds.

​Audit Your Summer Skincare Routine: Ensure your daily facial and neck creams are free from heavy synthetic perfumes and essential oils during high-UV months.

​If you are already dealing with fragrance-induced hyperpigmentation, advanced clinical treatments like professional chemical peels, microneedling, and targeted brightening serums can help break up the pigment and restore an even skin tone.
