Whether in cosmetics or aesthetic medicine, hyaluronic acid is one of the molecules most used in recent years to deeply hydrate devitalized skin and erase the signs of aging. How does it work, who is this technique for, what are the contraindications? We take stock.
Present naturally in the skin, at the level of the dermis and the epidermis, hyaluronic acid has the ability to retain water like a sponge. It then provides the necessary hydration to our skin, thus giving it a plump appearance and a fresh complexion. However, the production of hyaluronic acid decreases over time. Result? The oval of the face slackens, wrinkles deepen and the skin appears less toned. To fight against the effects of aging, it is possible to bring an additional dose of this moisturizing molecule to the dermis either by opting for daily care (creams, serums, etc.) formulated with hyaluronic acid, or by turning towards injections.
The fillers, a new makeover
For an immediate rejuvenating effect, fillers offer convincing results. This English term is translated by “injectables” which designates several types of facial treatments by injection of substances. Most often, these are injections of hyaluronic acid, intended to naturally fill deep wrinkles, redraw the contours of the face, lift the cheekbones or even increase the size of the lips, all in a very natural way (unlike the Botox which can sometimes give a frozen result). To do this, we use crosslinked hyaluronic acid with a strong volumizing power that will fill in the signs of aging and restore a more plump and taut appearance to the skin. Conversely, uncrosslinked – or weakly crosslinked – hyaluronic acid is used when we simply want to provide a dose of hydration to our skin. In each case, the fillers consist of injecting the hyaluronic acid under the skin – more precisely in the dermis and the epidermis – using a needle. When hyaluronic acid is crosslinked, it takes longer to be absorbed by the body, thus offering an immediate but above all lasting result (from 6 months minimum to 2 years depending on the products).
Adverse effects and contraindications
Although hyaluronic acid is naturally present in our body, it cannot be injected into everyone, especially people with an autoimmune disease, a known allergy to hyaluronic acid, a skin infection, in pregnant and lactating women. If we do not belong to these categories, no contraindication presents itself to us. However, it is important to respect certain precautions before opting for fillers, namely: prohibit taking aspirin, NSAIDs or vitamin C three days before the injection, taking acyclovir in the event of a history of cold sores and avoid sports, hammam, sauna and extreme temperatures for 2 weeks after the injection. Regarding the side effects, following the injection of hyaluronic acid, erythema, edema or hematoma may appear. After injection to the lips, inflammatory edema may also form, while in rare cases a granuloma (a small cluster of mononuclear cells) may proliferate. In general, before opting for a filler procedure, it is necessary to seek the advice of a doctor trained in these injection techniques. This gesture is not trivial and may involve risks, it is essential to have recourse to a professional. There are indeed more and more amateurs and fakes on the market that can have disastrous effects on our skin and our health.
