SOLIUS will determine your personal dose by adjusting your treatment duration within your first several sessions to optimize your body’s vitamin D production while minimizing the possibility of overexposure. We call this process is called the dose discovery phase.
Determining skin type
SOLIUS will start by determining your Fitzpatrick skin type. The Fitzpatrick skin typing system was developed in 1975 and is a commonly used method to classify a person’s skin type. This system classifies skin types based on skin appearance and response to sun exposure in terms of burning or tanning. The Fitzpatrick system divides individuals into one of six skin types, I-VI. The description for each skin type is shown in the table below:
| Skin Type | Appearance | Skin Characteristics |
|
Type I |
White, very fair skin; red or blond hair; blue eyes; freckles |
Always burns, never tans |
|
Type II |
White skin; fair; red or blond hair; blue, hazel, or green eyes |
Usually burns, tans with difficulty |
|
Type III |
Cream-white, fair skin with any eye or hair color |
Sometimes burns mildly, gradually tans |
|
Type IV |
Brown, Mediterranean white skin |
Rarely burns, tans with ease |
|
Type V |
Dark brown, Middle Eastern skin types |
Very rarely burns, tans very easily |
|
Type VI |
Black skin |
Tans very easily |
Determining exposure duration
Your first SOLIUS treatment will start at the lowest dose point for your skin type. Your exposure time will gradually increase over your first several treatments. Following each treatment, you will be asked to report pinkness (resembling mild sunburn) or skin color change should it occur. It is normal for pinkness or skin color change to occur at some point during the adjustment period. It is important you report any skin color change by answering the questions at the end of each treatment. This information will be used to determine your personal SOLIUS dose point for optimal vitamin D production while minimizing the possibility of overexposure.
