Summer is on the way, and you might be looking to get a Perfectha dermal filler treatment, to look and feel confident when you are enjoying the summer sun. While you are enjoying the heat and getting a tan, it is important to remember why and how to look after your skin and maintain the results of fillers. The sun emits waves of light, including the notorious ultraviolet (UV) rays. Those types most commonly reaching the earth’s surface are UVA and UVB. Neither are visible to the human eye however, can be felt as heat on the skin. The sun’s rays can have advantages including the induction of vitamin D production, however, an excess can be harmful.
It is commonly known that excess UV irradiation causes sunburn, inflammation, cancer and premature ageing, including wrinkles and sun spots1. Photoaging is the most common form of skin damage caused by long-term, repetitive exposure to the sun2. The UV ray’s damages cells and proteins structures in the skin, including collagen and hyaluronic acid.
Sun exposure, unfortunately, can also negatively impact fillers. It has been shown that UVB can drastically reduce the amount of hyaluronic acid (HA) in the skin as well as reduces the natural production of HA3. This data would therefore suggest, that over-exposure to the sun or sunbeds can reduce the longevity of fillers, by breaking down the HA in the fillers. Much like other lifestyle choices, including smoking; over exposure to the sun will accelerate the ageing process and will reduce the long-term benefits from HA fillers.
It is therefore important to protect your skin and fillers from the sun. You can protect your skin a variety of ways, including; sunscreen, seeking shade/reducing time in the sun and wearing a hat, are just to name a few. Using sunscreen and covering up are the most effective ways to slow down the degradation of fillers. They act as shields, reducing the amount of UV rays reaching your skin and causing potential harm.
Good rules to remember are to keep an eye on how long you are exposed to the sun and UV rays for. Remembering to reapply sunscreen with adequate SPF, especially if having been in water or having been sweating. Even if it is cloudy, UV ray exposure can still be high, so remember to use protection.
Other aftercare recommendations following a treatment with fillers include; Avoid applying makeup up to 24 hours following injections Avoid prolonged exposure to UV rays (direct sun exposure and sunbeds), temperatures below 0°C, saunas and Turkish baths for 2 to 3 weeks following injections
