Non-Invasive vs Minimally-Invasive Treatments

Are you wanting to improve your skin, but not quite ready to go under the knife? Fortunately, there is a large range of procedures which can rejuvenate your skin without any incisions needed. These are often referred to as non-surgical cosmetic procedures. There are two different types of non-surgical procedures you can have: non-invasive or minimally-invasive treatments.

Non-invasive treatments

Chemical Skin Peels

Chemical skin peels involve brushing a liquid onto your face. This removes dead skin cells and stimulates the production of new skin cells. This can make your skin appear healthier, cleaner and more evenly toned.

The chemical skin peels can be applied at different depths. These include:

  • Superficial peels: this removes cells from the top layer of the skin, and only requires the skin peel to be applied for a few minutes.
  • Medium peels: this removes cells from the top and middle layer of the skin. The skin peel is applied for a few minutes. The results should last from 6 to 12 months.
  • Deep peels: this works on the deeper layer of the skin, and may require a local anaesthetic when applied. You will feel a freezing sensation when the skin peel is applied. This treatment can cause swelling and redness which may last for weeks or months after the treatment. The results are long-lasting and you generally do not need to repeat the procedure. This may cause skin lightening, so it is not a suitable option for those who have darker skin.

There are two different types of chemical skin peels. These are:

  • Alpha hydroxyl acid (AHA): this is used to remove the cells from the top layer of skin. When using this type of skin peel, you may require several treatments to see the desired side effects.
  • Tricloracetic acid (TCA): this is used for medium skin peels, and you can experience longer-lasting results than with AHA.

There are numerous benefits to having chemical skin peels, including:

  • Removal of dead skin cells
  • Makes dull skin brighter
  • Evens skin tone and texture
  • Reduces the appearance of wrinkles
  • Hydrates skin
  • Reduces the effects of sun damaged skin
  • Results in smooth, softer skin



Microneedling involves the use of a dermaroller, which appears to be a small roller with lots of little needles on it. This is gently rolled in different directions across the skin. This boost the collagen production, which then reduces the appearance of wrinkles and fine lines, and can improve the texture of your skin. This is a preferable option for those who are looking to treat aged or damaged skin, those with acne scars, facial lines or stretch marks. Those whose skin hasn’t responded to chemical skin peels may wish to try microneedling.

Those who dislike needles do not need to worry about microneedling. Unlike traditional needles, a dermaroller has short needles – about 0.5mm to 3.0mm in length. Prior to any treatment, your face will be numbed with a cream to minimise any pain and discomfort. You may find the treatment slightly uncomfortable. After the procedure, you will experience some redness, however, this should return to normal the following day. During this period you should try and avoid any excess sun exposure.

Following the dermaroller treatment, you should gradually notice the results appear over six weeks. Improvements to your skin will be noticeable over the next few months. Most people choose to have three dermaroller treatments, however, you can have more than this if you choose.



Microdermabrasion is a non-invasive cosmetic procedure which removes dead skin cells to rejuvenate the appearance of your skin. This is done through the use of fine sterilised crystals and a vacuum. This helps to reduce fine lines and minor skin blemishes. It is a suitable choice for all skin types.

Microdermabrasion is suitable for those who have:

  • Fine lines
  • Dry skin
  • Mild acne
  • Congested skin
  • Blackheads

Microdermabrasion involves using a handheld device which leaves a fine stream of crystals across the skin. This loosens any dead skin cells. You do not need any local anaesthetic for this treatment. To see full results, you may require four to six treatments.

After the treatment, you may experience some redness and swelling. You may notice your skin feels dry and flaky, and you may even experience some bruising from the suction of the device. It is recommended that you avoid excess sun exposure for the first few days, as your skin will be more sensitive than normal.

Minimally-invasive treatments



For those who are wishing to reverse the signs of ageing without having a surgical procedure, injectables can be an attractive option. These include anti-ageing injectables and dermal fillers.

Anti-ageing injectables work to treat facial wrinkles. The most common application is botulinum toxin. This relaxes the muscles and prevents them from contracting, which then helps to remove wrinkles.

Dermal fillers fill out wrinkles and creases in the skin. There are numerous types of material which can be used for the filler, which will have different effects. This includes collagen, hyaluronic acid, calcium hydroxylapatite, poly-L-lactic acid (PLLA) and polymethylmethacrylate beads (PMMA).

Before having anti-ageing injectables or dermal fillers, you will be given the option of having a local anaesthetic, which will help to alleviate any discomfort. Your surgeon will then make injections into the desired site. For the forehead, this usually requires around four or five injections. The eyes require two or three injections around each eye. However, this will vary depending on the number of wrinkles and lines and the desired outcome.

After the injections, you may notice some redness and swelling, however, this will only last around 24 hours. It is recommended that you avoid coffee, alcohol, hot drinks and excess sun exposure for the first 24 hours.

Thread Lifts

Thread lifts are a great way to tackle skin that is sagging or has folds. This is often considered to be the non-surgical alternative to a facelift. A thread lift stimulates the production of collagen, tightens tissue, increases blood supply and restores firmness in the face, making the skin appear more youthful.

Non-surgical thread lifts are best suited for those aged between 35 to 55. Treatment usually involves the application of four to 16 threads. The threads, which are different lengths, are pulled up to create tighter skin. The procedure takes between 20 minutes to one hour to complete. If needed, thread lifts can be combined with other non-surgical procedures such as filler.

Results of a non-surgical thread lift will last about 10 to 18 months.

Lip Fillers

If you are unhappy with your pout and want to increase the size of your lips, you may wish to consider lip fillers.

Thin lips can occur as a result of ageing, or the lips can just be naturally smaller than we would like, making them look out of proportion with the other features of the face.

Surgeons will be able to increase the size of your lips by using dermal fillers. You will be able to change the size of both lips, just the top or just the bottom by as little or as much as you wish. However, if the surgeon believes the filler is too large they may refuse to administer the lip fillers.

The surgeon will inject dermal fillers into your lips, slowly increasing the volume. This will take around 15 to 20 minutes to complete. You will be able to see the results of the lip filler instantly, however, you will experience some swelling so the size will decrease. This will occur over a few months.  The lip injections will eventually break down, so if you want to maintain the size of your new lips, you will need to continue to have lip filler.
