You will need three clear images of your skin, like below.

Clean your lens - use a soft lint-free cloth to wipe down your camera lens to ensure crisp images.

Use natural light - stand near a window for even lighting. Also avoid using shadows or flash.

Keep it bare - no make or filters please.

Hold the camera steady - keep your phone at eye level with a neutral expression.

Remove accessories -items like hats, glasses and scarves that cover your faces can affect the analysis.

Neutral Background - use a plain or light coloured background to prevent distraction and keep the focus on your skin.
