Preparing for your photorejuvenation appointment in Geneva

Photorejuvenation is an aesthetic medical technique that improves skin quality through light energy. This technology is used to treat several skin changes linked to ageing or environmental stresses, such as pigmentation spots, diffuse redness, loss of complexion radiance or certain texture irregularities. This treatment is particularly valued because it gradually improves skin quality without invasive techniques. However, careful skin preparation before the session is essential to ensure treatment effectiveness and limit adverse effects. Good preparation not only optimises photorejuvenation results but also protects the skin and ensures faster recovery after the session. 

What is photorejuvenation ?

Photorejuvenation uses laser light that targets certain structures in the skin. The heat generated in the dermis stimulates fibroblasts, the cells responsible for collagen production. This stimulation helps improve skin density, complexion radiance and the overall quality of skin tissue. Photorejuvenation is often used to rejuvenate the skin, brighten the complexion and improve certain irregularities in skin texture.

Why is skin preparation essential before photorejuvenation ?

The skin must be in optimal condition before the session to ensure treatment safety and achieve the best possible results. Skin recently exposed to the sun or weakened by certain dermatological treatments may have a higher risk of complications, particularly burns or pigmentation disorders. Preparation also helps limit factors that could interfere with the light used during treatment. In practice, several measures must be followed in the weeks before the session to prepare the skin properly.

Avoid all sun exposure before the session

The most important instruction before laser photorejuvenation is to avoid all sun exposure. Tanned skin contains a higher concentration of melanin. The light used during treatment specifically targets this pigment. If the skin is tanned, the epidermis may absorb excessive light energy, increasing the risk of burns or hyperpigmentation. It is therefore recommended : • To avoid sun exposure for at least four weeks before the session. • Not to use sunbeds. • To apply daily sun protection. This precaution is fundamental to ensure treatment safety.

Adjust your skincare routine before photorejuvenation

Certain cosmetic products can make the skin more sensitive to light. Products containing exfoliating or photosensitising ingredients should be used cautiously in the days before the session. It is generally advisable to temporarily discontinue retinoids, exfoliating acids (AHA, BHA) and certain irritating dermatological treatments. This break helps reduce the risk of skin irritation and makes the skin less reactive before treatment. A gentle skincare routine is preferable during this period, with moisturising and repairing products to strengthen the skin barrier.

Inform the doctor about certain treatments or medicines

During the preliminary consultation, it is essential to inform the doctor about all ongoing medical treatments. Certain medicines can make the skin more sensitive to light, including certain antibiotics, dermatological treatments and photosensitising medicines. In these situations, it may be necessary to postpone the session to ensure treatment safety. The medical consultation also identifies any contraindications to photorejuvenation.

Prepare the skin in the days before the photorejuvenation session

In the days before treatment, a few simple precautions help optimise skin tolerance. It is recommended to : • Keep the skin well moisturised. • Avoid scrubs for two weeks beforehand. • Avoid chemical peels in the preceding month. • Avoid hair removal on the treatment area for one week before the session. The skin should be well moisturised and free from irritation at the time of treatment.

On the day of the photorejuvenation session

On the day of treatment, certain recommendations must be followed to ensure appropriate conditions for the procedure. The skin must be perfectly clean and free from make-up. It is preferable not to apply cream, perfume or make-up to the area to be treated. The doctor then cleans the skin. Protective eyewear is worn during the session to protect the eyes from intense light. The treatment itself is relatively quick. Depending on the treated area, a session generally lasts between fifteen and thirty minutes. Patients most often feel warmth or slight tingling as the light pulses are delivered.

Immediate after-effects following the session

After photorejuvenation, the skin may show certain normal, temporary reactions. Mild redness, a feeling of warmth and slight swelling are common. These reactions generally disappear within a few hours. Sun protection is absolutely essential for two months after the session to prevent pigmentation disorders.

How many photorejuvenation sessions are needed ?

Photorejuvenation produces gradual results. In most cases, several sessions are needed to achieve a visible and lasting improvement in skin quality. A protocol generally consists of three to five sessions, spaced one month apart. The exact number of sessions depends on the skin's initial condition, the patient's goals and the ability to tolerate a few days of social downtime. Annual maintenance, one session per year, is offered to preserve the results.

The importance of a medical diagnosis before treatment

A medical consultation is essential before any photorejuvenation session. It allows the patient's skin to be analysed precisely, the treatment indications to be identified and any contraindications to be ruled out. Every person's skin has specific characteristics, particularly regarding pigmentation and sensitivity. The device settings must therefore be precisely tailored to each patient to achieve optimal results while ensuring treatment safety. Modern aesthetic medicine relies on a personalised approach, with every treatment tailored to the skin's needs and individual characteristics.

Preparing your skin to optimise photorejuvenation results

The success of laser photorejuvenation does not depend solely on the technology used and the doctor. Skin preparation plays an essential role in treatment effectiveness and safety. Avoiding sun exposure, adjusting the skincare routine and following medical recommendations create ideal conditions for the skin to respond favourably to the light used. Well-prepared skin tolerates treatment better and benefits fully from photorejuvenation, gradually achieving a more radiant complexion, improved skin texture and visibly more even skin.
