For even better results, some conditions may require combination treatments with ART Aesthetic Surgery procedures. ART Dermatology consists of non invasive procedures with zero to short recovery time).

Below are some useful information on common conditions (not exhaustive and not meant to be a replacement for a visit to your aesthetic doctor).

PIGMENTATION / UNEVEN SKIN TONE

Freckles, Lentiges, melasma and Pigments

Pigmentary changes on our skin is something nobody wishes to have. But unfortunately in our Asian population, hyperpigmentation (increase in pigment in our skin) is a common and sometimes distressing problem.

Much of the root of the problem comes from our tendency to sun exposure (UV radiation), and when coupled with factors like genetic predisposition, drugs and pregnancy, we can develop a variety of skin pigmentary changes.

In order to have optimal treatment, it is important to ascertain if the pigmentary lesions are epidermal or dermal. Many patients have a combination of both types of pigmentation. Examination under a Wood's lamp can help in our clinical assessment.

EPIDERMAL PIGMENTATION

Freckles and Lentiges

These are by definition, epidermal lesions on skin. (The epidermis is the outermost layer of our skin, as opposed to the layer beneath the epidermis which is called the dermis)

What are freckles and lentiges?

Freckles (or Ephelides) are very common and can be easily treated. They are small brown macules (flat lesions) on the face or other sun-exposed areas.

However most patients will have a combination of comedones and inflammatory acne and using a retinoid by itself may not be good enough. In such circumstances, our experience is that a combination of a topical retinoid (trans-retinoic acid; Vitamin A acid) together with potent home care products containing a variety of actives such as salicylic acid, benzoyl peroxide and Azelaic acid can show dramatic results. A course of oral antibiotics may be added if there are many red papules and/or pustules seen.

Lentiges are similar to freckles but are a different entity. They tend to be a darker shade than freckles. Solar lentiges can be found on the back of the hands, and face. There are usually associated sun related changes like wrinkling and dryness, and in combination are sometimes referred to as signs of photoaging.

How can freckles and lentiges be treated?

We use the Q-switched Nd:YAG laser system to treat freckles and lentiges . This laser targets epidermal melanin via the concept of selective photothermolysis.

Post procedure, the pigmentation will darken, develop a "scab" and eventually fall off in a few days to a week's time. Sometimes, a second session may be required for complete clearance.
