Nothing Lasts Forever: How to Prolong Your Tan
The last days of summer, the last warm evenings… Is it possible to preserve a trace of those sun-filled days on our skin?
A beautiful tan is a reminder of relaxing summer days and, for many people, the focus of an extensive skincare routine. You have probably wondered more than once how long it can be maintained. That golden-brown glow gradually fades because the layers of the epidermis containing melanin granules are progressively shed. It is no secret that without sufficient UV exposure, the effect will eventually disappear. To slow down this process, however, we can work from both the inside and the outside.
The first general rule, which we all know, is to keep the body properly hydrated.
The second is to ensure an adequate intake of B vitamins, beta-carotene, vitamin C, vitamin A, and biotin.
The third rule is to moisturize the skin externally — or, more precisely, to prevent moisture loss. This can be achieved with a variety of ingredients:
humectants (glycerin, propanediol, pentylene glycol) — they bind water
collagen — forms a film on the skin’s surface that helps reduce water loss
hyaluronic acid — molecular size does not matter; all forms help reduce TEWL
panthenol — binds water while also supporting skin regeneration
various “sugars” (trehalose, glucose, xylitol, sorbitol, inulin)
components of the skin’s natural moisturizing factor (NMF), including low concentrations of urea, lactic acid, sodium lactate, and amino acids. However, the concentration must be carefully considered, as these ingredients can have an exfoliating effect at higher concentrations.
The fourth rule is proper lubrication. It is worth investing in natural butters and oils to replenish the depleted intercellular cement. This is important because an intact hydrolipidic film forms the skin’s primary barrier against excessive water evaporation from the epidermis. It is not a direct form of hydration, but it is an extremely effective way to help maintain skin moisture.
Shea butter, cocoa butter, olive oil, hemp oil, and coconut oil work particularly well in this role. They contain fractions rich in components similar to those found in human sebum, including triglycerides, squalane, and fatty acids. These substances are highly compatible with the skin and can have beneficial effects on its condition.
Unfortunately, nothing lasts forever. A summer tan will eventually fade after a few months, and even the best dietary supplements or body lotions cannot stop this process. For those who simply cannot bear to part with their tan, there are always self-tanners and tanning beds :)
