"It shows the amount our skin has versus the water it can retain," Daniel Meredith, director of customer experience at Kiehl's said.
Kiehl's is a skin care brand created in New York City in 1851 and uses a blend of cosmetic, pharmaceutical, herbal, and medicinal knowledge to develop products for the face, hair and body.
A reading on their analysis tool of 30 or below means the skin is severely dehydrated, between 30 to 50 means its somewhat dehydrated and above 50 means its hydrated.
Once the hydration level is determined, experts can explain what areas in the skin care routine might need improvement.
Heyday, a one-stop shop for skin care products and expert advice, has estheticians available to study the face to determine where there might be clogged pores, dead skin cells and irritation.
Also, a UV light is used to check for sun damage and determine if the t-zone is active. Many people experience dryness in their skin because they think they have to over-clean in order to remove all oils.
But the skin has to retain essential oils in order to keep it hydrated and looking youthful. With the help of a UV light, estheticians can determine the activeness of the t-zone and if someone has oily, normal or dry skin.
Understanding your skin type and problem areas you want to solve can help you understand what works best for each phase of the skin care routine.
Step 1: The cleansing phase

"A cleanser is necessary," Meredith said. "You've got to remove the pollution."
While clean skin is the goal, a harsh cleanser isn't required in order to get the best results.
Most skin types should turn towards a toner that is free of alcohol to prevent causing dryness and irritation.
MILK Makeup Matcha Toner, $26 (NZD $49), is made with green tea which has antioxidant qualities to protect the skin barrier.
Salicylic acid is an ingredient you should look for in your toner if you are trying to fight acne.
The acid is oil-soluble meaning it can penetrate deep into the pores and fight the acne at its root.
Heyday's Clear Cell Salicylic Clarifying Tonic toner, $24 (NZD $45), provides that extra step towards clean skin and fights any unwanted blemishes.
Step 3: The serum phase
Serums are applied after the toner so all layers of the skin can absorb the nutrients. This helps the skin get necessary nutrients such as vitamin D or vitamin C. Photo / 123RF
"The serum is the medicine for the skin," said Meredith.
Another popular nutrient found in some serums is vitamin C, which is a key component for brightening the skin and diminishing dark spots.
It does this because it promotes the production of collagen in the skin to help replenish uneven skin tones.
Even though these serums say they are "dark spot correctors", they should still be applied to the entire face.
The vitamin C in Kiehl's Clearly Corrective Dark Spot Solution, $50 (NZD $94), works to even the skin tone and rid the face of any marks that occurred from acne.
Step 4: The moisturizer phase

No matter what the skin type, moisturizer is a necessary step for both morning and night routines to hydrate the face.
It helps prevent dry patches across the skin and influences how the essential oils are retained in the face.
Lush Ocean Salt and Facial Body Scrub, $37 (NZD $70), is an exfoliator for all skin types and is adjustable based on the oil levels in your own face.
If you are looking to take your exfoliating routing to the next level, then facials once a month might be the best option.
Skin experts recommend investing in these one-a-month treatments because it allows a professional to guide someone on what is going on with their own skin.
Stores such as Heyday offer customized facials that are geared towards someone's own skin.
This can help you pick out products that will give you the improvements you are looking for from your skin care routine.
