Birch Sap for Skin: Benefits, Uses & Why We Formulate With It

When we think about skincare, we often focus on the products we apply directly to our skin.

But some of the most meaningful forms of support come from simpler, seasonal ingredients that have been quietly used for generations.

Fresh birch sap is one of nature's most treasured Nordic skincare ingredients—and one we've chosen to formulate with instead of distilled water.

What Is Birch Sap and Why Is It Used in Skincare?

Birch sap is the clear, mineral-rich liquid that rises through birch trees in early spring as they awaken from winter dormancy.

It can only be harvested during a short window each year and has traditionally been enjoyed throughout the Nordic countries as both a refreshing drink and a gentle ingredient in skincare.

Naturally, fresh birch sap contains minerals, vitamins, amino acids and natural sugars that help support healthy skin. Its lightweight composition makes it a beautifully hydrating ingredient that works in harmony with the skin, leaving it feeling fresh, soft and comfortable.

Benefits of Birch Sap for Skin

Fresh birch sap offers more than simple hydration.

Because it naturally contains minerals, vitamins, amino acids and natural sugars, it helps support the skin's natural balance while providing lightweight hydration without feeling heavy or greasy.

The benefits of birch sap for the skin are:

• Deep hydration 

• Cell renewal
  
  
• Improved skin tone
   
  

• Strenghten and support the skin barrier

• Helping reduce skin redness
  
  

• Leaving skin feeling soft, fresh and comfortable
  

• Supporting healthy-looking skin with naturally occurring minerals and amino acids
  

Unlike other hydration ingredients, birch sap has an exceptionally light texture that absorbs beautifully into the skin, making it suitable for daily use and all skin types.

Why We Use Fresh Swedish Birch Sap Instead of Distilled Water

Many skincare products use distilled water as their primary ingredient, around 60-80% of the formulation. 

At Imogen, we take a different approach.

Instead of distilled water, we formulate with freshly harvested Swedish birch sap, allowing every part of the formula to actively support the skin.

Rather than serving as an inactive base, fresh birch sap contributes its own naturally occurring nutrients, making hydration more purposeful from the very first ingredient.

It's a small change that reflects our philosophy: every ingredient should have a purpose.

A Truly Seasonal Ingredient

Fresh birch sap is only available for a brief period each year—typically just two to three weeks in early spring.

That limitation is part of what makes it so special.

Harvesting birch sap requires us to work alongside nature's rhythms rather than trying to control them. It encourages a slower, more intentional way of creating skincare that respects the changing seasons.

For us, seasonality isn't an inconvenience. It's a reminder that nature already knows the right time.

Where We Use Birch Sap

We choose fresh Swedish birch sap for formulations where hydration, skin balance and aging well are at the heart of the product.

Forest Blossom Moisturiser

In our Forest Blossom Moisturiser, fresh birch sap provides long lasting hydration and nourishment while helping the skin feel soft, comfortable and balanced.

It also acts as an excellent carrier for other active ingredients in the formulation, helping them work in harmony with the skin.

Triple Tree Face Mist

In our Triple Tree Face Mist, the birch sap instantly hydrates and refreshes the skin while helping to support the skin's natural barrier. Rich in naturally occurring minerals, vitamins and amino acids, it helps leave the complexion looking more even and feeling calm and comfortable throughout the day.

Frequently Asked Questions

Can you drink birch sap?

Yes. Fresh birch sap has been enjoyed throughout the Nordic countries for generations as a refreshing spring drink. It has a naturally mild, slightly sweet flavour and is traditionally collected during the same short seasonal window in which we harvest it for our skincare.

How do you harvest birch sap?

Birch sap is harvested for only a short period each spring, when the trees begin moving water and nutrients from their roots to their branches. A small hole is carefully drilled into the trunk and the sap is collected before the opening is sealed, allowing the tree to naturally heal. When harvested responsibly, birch sap can be collected year after year without harming healthy trees.

Can birch sap help reduce the appearance of fine lines and wrinkles?

Birch sap naturally contains minerals, vitamins, amino acids and natural sugars that help support hydrated, healthy skin. Well-hydrated skin looks smoother and more supple and plump, which helps minimise the appearance of fine lines and wrinkles. While birch sap isn't a wrinkle treatment, it can be a valuable ingredient in a skincare routine focused on supporting healthy skin as it ages.

Is birch sap suitable for sensitive skin?

Birch sap has long been valued in Nordic skincare for its gentle, hydrating properties. A 2023 clinical study of a skincare formulation containing 88% birch sap found significant improvements in skin hydration, skin barrier function, transepidermal water loss (TEWL) and visible redness after four weeks of use, making birch sap a valuable ingredient for sensitive skin (1). 

Is birch sap good for rosacea?

Rosacea is commonly associated with an impaired skin barrier and increased transepidermal water loss (TEWL), making it more difficult for the skin to retain moisture. While birch sap is not a treatment for rosacea, ingredients that support the skin barrier and improve hydration can help support healthier-looking skin. In the same 2023 clinical study, a skincare formulation containing 88% birch sap significantly improved skin hydration, reduced TEWL and decreased visible redness after four weeks of use (1).

Is birch sap good for eczema?

Eczema is closely linked to a compromised skin barrier and increased moisture loss. While birch sap is not a treatment for eczema, maintaining hydration and supporting the skin barrier are important for healthy skin. Naturally rich in minerals, vitamins and amino acids, birch sap provides lightweight hydration while helping to support the skin's natural barrier.

Is birch sap good for perioral dermatitis?

Perioral dermatitis often benefits from a simple skincare routine that focuses on protecting the skin barrier and avoiding unnecessary irritation. While birch sap is not a treatment for perioral dermatitis, its lightweight hydration and skin barrier-supporting properties make it a valuable ingredient in gentle skincare formulations.
