Skin Lab – 6 Skin Factors in Skin Analysis

Skin Lab identifies 6 different parameters which can be measured to create a comprehensive and personalised skin profile. We look at these factors more closely:


Skin Colour

At Santi we offer many treatments for skin pigmentation ranging from the popular Vitamin C Boost and Sugar Cane Peel, which provide a general brightening, to cutting-edge approaches like Dermamelan. Hyper-pigmentation, including melasma and chloasma, often requires targeted treatment when traditional skin lightening techniques fail. With Skin Lab technology we are able to accurately gauge the effectiveness of pigmentation treatment by measuring minute changes in skin colour – both the melanin and the skin’s redness, or ‘erythema’ – at a magnification of fifty, far beyond the naked eye. Skin Lab’s skin colour facility can also quantify your skin’s ‘tan level’ if you are considering laser hair removal, so your treatment will be safe and effective.


Trans Epidermal Water Loss

Trans Epidermal Water Loss (or TEWL) is the rate at which your skin loses moisture, a factor notoriously difficult to quantify – and frequently the source of both dryness and oiliness. One of the many concerns we hear is that the skin may be dry but also too oily. Ever wondered about this paradox? Often, dryness and oiliness coincide as the skin works to compensate for high level moisture loss, that is, your skin could be well-hydrated but losing too much water through evaporation. By assessing the incidence of TEWL we can right this balance with adjustments to your moisturising and skincare routine. If your TEWL readings are high we can advise on skin care that not only hydrates the skin but also protects it with a layer on top to prevent high TEWL – rectifying the problem of ‘dryness’.


Elasticity is a scientific means of measuring ‘youth’ – that is how plump or firm is your skin and its surrounding tissue? In youth our skin is firm and supple thanks to high collagen & elastin levels. While collagen plays a structural role, elastin is the ‘bounce’ that begins to lessen as we age. Elastin decline can be slowed by eliminating smoking and sun exposure and increasingly diet is found to play a protective role, particularly foods rich in vitamin A and betacarotene. While research continues into prolonging skin resilience, measuring elasticity gives us a clear picture of your skin’s condition in relation to age. Skin Lab is able to quantify this key factor by measuring the structure and the ‘give’ of your skin, assigning it an elasticity score between 1 and 100, and comparing these scores over time.


Hydration is key to maintaining your skin’s health and appearance – it is the prime factor underpinning resilience and youthfulness and our best defence against harmful toxins. Hydration can be confusing and we often make mistakes in our product choices, opting for harsh or inappropriate creams that can lead to further dehydration. By assigning your skin a hydration score from 0 to 100, we can accurately identify your skin type and help you choose more suitable products, especially as the seasons change. Skin Lab uses a probe to assess moisture accumulation and assigns a score on that basis – giving you a clearer view of the nature of your skin’s dryness, and the knowledge to combat it more effectively.

Collagen Level

Collagen is a strengthening protein fibre found throughout the body, in bones, teeth, artery walls, cartilage, ligaments, tendons – and skin. In the skin collagen determine plumpness and structure, effectively keeping gravity at bay. Closely associated with skin thickness, another typical marker of youth, collagen levels begin to decline in our mid-twenties with the loss-rate accelerating as we age. If you’ve ever wondered whether your products are actually having an effect on your collagen structure, Skin Lab can take an ultrasound ‘snapshot’ and give you an accurate answer. We can identify your collagen levels, skin thickness, and give you a dynamic picture of how your measurements change over time.
