“Fragrances are designed and tested to work on the majority of skin types, but they can sometimes smell different depending on various factors contributing to our individual skin chemistry,” says Gilbert.

“The pH level of our skin can affect how fragrance molecules interact with it, potentially altering the scent. Skin type also plays a role – oily skin can hold scents longer, while dry skin may not retain them as effectively.

“Diet and hormones can change our body odour, which mixes with the fragrance and personal care products like lotions and soaps can interact with the perfume. These variables can enhance or diminish certain notes, leading to a slightly different scent experience for some people.”

If you feel like you’re looking for something longer-lasting, seek out a more intense fragrance with these specific notes.

“Amber brings warmth, richness and a sensual depth to the scent,” says Gilbert. “While pink peppercorn is a fresh, elegant spicy note that adds sophistication.”

With these notes found in both BOSS The Scent Elixir For Her and BOSS The Scent Elixir For Him, these twinned scents are ideal for gifting to a couple or for someone with a more defined scent palette.
