Restylane ® (inc Emervel Collection)

Product Summary

NASHA hyaluronic acid technology

This brand has a lot of support from practitioners and is currently one of the most popular dermal fillers used in the U.K..

Since the manufacturer, Q-Med, (now part of Galderma) launched Restylane® in 1996 it is estimated that over 15 million treatments have been carried out worldwide (data as at 2013). The product range has since been expanded to consist of differing sizes of gel particle specifically designed for use in certain areas of the face.

As of 2009, some of the product range is available with the addition of 0.3% lidocaine (Restylane® Lidocaine and Restylane® Perlane Lidocaine) for improved patient comfort.

In 2016, the EMERVEL range of hyaluronic acid-based fillers, also from Galderma, was integrated into their Restylane range to create one large range of hyaluronic acid fillers incorporating NASHA Technology and Optimal Balance Technology into one product brand. This meant that EMERVEL ceased as a brand name and all product derivatives were renamed.

The product brand also include Restylane SkinBoosters

Restylane® Eyelight™ was released in 2022 to combat tired-looking eyes. When we lose (or simply lack) volume in the tear trough area, it gives rise to a hollowness, a groove, under the eyes. The groove deflects the light and casts shadows onto the skin, leading to dark under-eye shadows that make us look tired and fatigued. Using NASHA® technology, Restylane® Eyelight™ treats the root cause of the problem – the lack of volume – by filling up the groove, making the area smooth again, with reduced hollowness, so that light can reflect differently from the skin.

How is it made?

The products which form part of the EMERVEL collection benefit from what the manufacturers call its Optimal Balance Technology™.

Hyaluronic acid is completely broken down within the skin over a period of months, eventually leaving no trace of the filler.

This group of products, marketed as RESTYLANE Skinboosters is aimed at a whole new approach to skin rejuvenation, using mesotherapy, (sometimes called biorevitalisation) techniques. It is targeted at a broad range of treatment areas including the face, neck, décolletage (the area between the neck and breasts) and hands; designed to replenish the hyaluronic acid lost through ageing, hence hydrating the skin and improving its elasticity and tone. For more information, please see our Restylane® SkinBoosters page.

Restylane Touch (discontinued)

Has the smallest gel particle size in the Q-med range and is used for the correction of very thin superficial lines. It is injected into the upper part of the dermis. This product is now discontinued in light of the Restylane Skinboosters range.


Restylane Lip Volume (discontinued)

This product was originally branded as Restylane Lipp but was later rebranded as Restylane Lip Volume. It has been specially designed and formulated for injecting into the lips for enhancement and contouring of thin looking lips, the cupid’s bow, or to simply add fullness. It claims to be structured to withstand the range of mouth movements and strains – like talking, smiling, laughing and kissing - that characterise the lip area and therefore last longer. This product has also been discontinued and replaced with Restylane Kysse, formerly EMERVEL Lips.


SubQ (discontinued)

It has the largest gel particle size in the range and is used to replace fat loss in the face and create or restore a more defined facial contour. The procedure requires a larger needle and deeper injections below the skin layers.

This product is promoted as an alternative to fat transfer . As a result, you will find fewer practitioners who are adequately trained to use SubQ.


Not to be used in

Individuals with a known hypersensitivity to hyaluronic acid.


Duration of effect

This depends upon the degree of correction required, your age and lifestyle as well as the correct placement of the product by a practitioner.

Clinical trials indicate that it is effective for six to twelve months for the treatment of wrinkles and for around six to nine months for lip augmentation.


Reported side effects

Transient erythema (redness), swelling, pain, itching, discoloration or tenderness at the implant site. Typically resolution is spontaneous, within one or two days after injection into the skin, and within a week after injection into the lips.

Additionally, temporary palpable lumpiness has been noted after injection in some patients.

Localised reactions thought to be of a hypersensitivity nature have been reported in about 1 in every 2000 treated patients. Redness, tenderness and rarely acneform papules may occur.

In addition in rare cases (in less than 1 in 15,000 treatments) granuloma, superficial necrosis and urticaria have been reported.



Again, this depends on area treated and how much is required, and the practitioner doing the treatment, but ranges are in the region of: £250 to £400 per treatment.
