But the 27-year-old has told how a £15 coffee scrub, as well as a £7.50 moisturiser, made dramatic improvements to her skin almost instantly.
Writing on her blog, Itchie Scratchie, 27-year-old Lydia from London revealed how her eczema "hit her like a ton of bricks" when it first flared up in November 2016.
"I scratched and scratched and bled and scratched more. I wasn't sleeping," she said.
"Every part of my body was covered in red raw, itchy, flaky, bleeding, blistered hell, and I mean EVERY part.
"Eczema hit me like a ton of bricks, I had never suffered like this before, but it spiralled to the point where I had no control. I was blaming everyone for everything."
But after trying Grounded's Coffee Body Scrub, which you can buy for £15, Lydia explained she saw a difference almost immediately.
She explained: "I've been using the scrub for a few years now. This scrub was on Dragon's Den - a guy made this to treat his girlfriend's eczema and it worked!
"I use the grapefruit one - it is the softest texture and smells amazing. It is full of vitamins and moisturising ingredients. The coffee/salt exfoliates any dry skin if I leave it on for more than minutes, I notice instantly smoother skin.
"Be super gentle when you put it on though. It feels GREAT to itch with, so you can irritate your skin by over-doing it (which I have done MANY times because my self-control is ZERO when it comes to itching haha)."
Lydia went on to tell Tyla: "It made my skin feel so soft - like noticeably better and a great exfoliator. Full of good ingredients that I know moisturise my skin.
"It can sometimes tingle when putting on sore skin - and I wouldn't put on oozy or cracked skin - because it'd be too harsh/painful and could irritate skin more. Just once a week, gently, works wonders."
In conjunction with the coffee scrub, Lydia also uses Aveeno moisturiser, available for around £7.50.
"The difference in terms of how soft your skin is is genuinely instant - but over a number of months of weekly scrubs and daily use of Aveeno emollient cream I saw a difference," she told us.
"I used them together, the Aveeno strengthened my skin barrier again and the scrub helped with exfoliation and hydration plus my general mental health and state of mind improved."
But how does the coffee scrub work? Tyla spoke to dermatologist Patricia Boland from Colorescience UK, who explained that although caffeine from consuming coffee - for example - can be known to worsen eczema, the granules are actually rich in antioxidants.
"Antioxidants help to fight skin inflammation and repair the damage that occurs from it, making it a great ingredient to heal skin conditions such as psoriasis, cellulite, acne and of course, eczema," explained Patricia.
"The ingredients of the Grounded Coffee Body Scrub also include salt and sugar, which allows for the scrub to kill any harbouring bacteria, heal infections and gently exfoliate the skin.
"The range combines coffee with other natural ingredients such as coconut oil, vitamin E and sweet almond oil, which will help to enhance the texture of tired looking skin.
"As with any new product you use on the skin, you should do a patch test to determine whether a specific substance will cause further inflammation.
"Eczema prone skin needs plenty of moisture,
so after exfoliating be sure to use a fragrance free, thick lotion designed for dermatitis."
