An undertone is the color beneath the surface of your skin, which never changes (even with a tan). There are three types of undertones:
Pink/Cool
I see red or pink undertones around the perimeter of my face and neck.
My skin burns easily, but barely tans.
My skin looks better in silver jewelry than gold.
Neutral
I see both pink and yellow undertones around the perimeter of my face and neck.
My skin sometimes burns and sometimes tans.
My skin looks good in both gold and silver jewelry.
Yellow/Warm
I see yellow or golden undertones around the perimeter of my face and neck.
My skin rarely burns, but tans easily.
My skin looks better in gold jewelry than silver.

create accountUnder Your Skin is a Swedish beauty brand redefining clean beauty with powerful, plant-powered products crafted to care for you and the planet. Combining the purity of Swedish nature with innovative science, our formulas are designed to deliver transformative results without compromise—helping you feel confident and cared for in every step of your routine. Founded by mother-and-daughter duo Lovisa and Christina, our story began with a personal mission. After Lovisa experienced a hormonal imbalance in her 20s, they uncovered the dangers of synthetic ingredients in everyday cosmetics. Determined to create a better alternative, they blended nature’s finest ingredients with innovative science to craft products that prioritize safety and efficacy. From turmeric stem cells in our Density Shampoo to milk thistle in our Clean Shampoo, our formulations are rigorously tested by external toxicologists and dermatologists. We ban over 2,100 harmful substances—far exceeding European and U.S. standards—to ensure every product is as clean as it is effective. Guided by a commitment to sustainability, we source ingredients close to our Swedish manufacturing to reduce our environmental impact. Vegan, cruelty-free, and free from parabens, SLS, and SLES, Under Your Skin is beauty that transforms, protects, and empowers—inside and out.

"My hair has been growing in since I started using these drops."
— Kimberly W. (5/5)
"I just started using this product, but so far so good. I like that it does not have a scent and it does not leave my hair greasy. The store associate highly recommend this brand and I would like to try their other products."
— Colleen F. (5/5)
"I noticed some shedding and these helped! My hair is thick and I get compliments all of the time!"
— Isa (5/5)
"I have been using the density drops for 4 months now and am seeing noticeably fuller, thicker hair. I like that it has a non-oily formula that doesn't leave my hair greasy at all."
— Lee O. (5/5)
"Think a few times before you shop. These three are on discount all the time🤷 :female_sign: there are better preparations on the market. Horrible customer service."
— Camilla A. (1/5)
"Used the product for four months and see no results at all even though I used it according to all the rules of the art. Unfortunately, I didn't take pictures every month because then I would have asked for the money back, but the picture I took when I started and how it looks now, there is zero difference. Sad when you spent so much money on it!"
— Isabella B. (2/5)
"Hello! I wonder what the Hair Growth Activating Serum smells like? As it should not be rinsed out. Does not stand."
— Sofia (5/5)
"My scalp has never felt so good!! For as long as I can remember I have had dandruff and sores and a scaly scalp, now I use both serum, shampoo and conditioner from UYS and both my hair and scalp feel great!"
— Daniela J. (5/5)
"The serum runs out way too fast. How is it supposed to last more than a week if you are to apply 2gg/day? SEK 400/week does not work. Sorry, otherwise I love your products."
— Angelica S. (2/5)
"I have a question about using the serum. You advise to rinse the hair in cold water after washing to make it extra shiny. But should I then wait to apply the serum? What I mean: does the cold water cause follicles and pores to contract making it harder for the serum to penetrate? Regarding the products themselves, after two months I have a little difficulty in determining whether the growth has increased. However, I can clearly see that I'm losing less hair, which also makes it longer (the hairs have a longer period to grow before they fall out) and my hairdresser commented that my hair looked much healthier and wasn't so worn at the ends 😃"
