ANUA – Birch 70% Moisture Boosting Serum (30ml)

The anua serum you have been searching for is here. The Birch 70% Moisture Boosting Serum (30ml) is Anua’s results-led Korean serum, formulated to deliver real, repeatable hydration and brightness without the marketing fluff. Below we cover exactly what it does, the key ingredients, how to layer it in your K-Beauty routine, who it suits best, and what to expect after the first bottle.

Why choose this anua serum?

This anua serum is engineered as a targeted treatment step for modern K-Beauty routines. It sits after toner and before moisturiser, designed to boost brightness, hydration and skin texture in one lightweight step.

Compared to mass-market Western equivalents, Anua leans on expertise-led Korean labs, lighter textures and a strict focus on barrier-safe actives. The result is a serum that works with your skin rather than against it.

• Clean, results-led formula – Birch water, hyaluronic acid, niacinamide, peptides and plant ferments.
• Cosmetically elegant – lightweight feel, fast absorption, no sticky residue.
• Routine-friendly – layers cleanly with essences, masks, eye creams and SPF.
• Authentic UK supply – sourced directly from Anua or an authorised distributor, with an English INCI sticker on every bottle.

What makes birch water the hero ingredient?

Birch water – present at 70% concentration – is the defining ingredient of this anua serum. It is rich in minerals, amino acids and natural sugars that draw moisture into the skin and support a healthy barrier without heaviness.

Birch water is gentler and more biocompatible than many synthetic humectants, making this serum particularly well-suited to sensitive and combination skin types. Korean cosmetic formulators have championed it for years; it is now earning wider recognition among global skincare communities such as r/AsianBeauty.

Key ingredients in the anua serum

Korean cosmetic chemistry excels when actives are layered intelligently. The key ingredients in this anua serum work together across four functions:

• Hydration anchors – birch water (70%), glycerin and hyaluronic acid draw and retain moisture throughout the day.
• Barrier support – plant-derived lipids help reinforce the skin’s natural protective layer.
• Brightening notes – niacinamide targets uneven tone and helps minimise the appearance of pores.
• Skin-renewal support – peptides and plant ferments contribute to a smoother, more refined texture over time.

The full INCI list ships in English with every UK order, so you can verify exactly what is inside before use.

How to use the anua serum correctly

Correct application makes a measurable difference to results. Follow these steps for the best outcome from your anua serum:

1. Cleanse – oil cleanse first if you wear SPF or makeup, then follow with a gentle water-based cleanser.
2. Tone – a hydrating toner rebalances pH and primes the skin to receive actives more effectively.
3. Apply – dispense a few drops or a pea-sized amount and press into clean, slightly damp skin for better absorption.
4. Pat, do not rub – gentle pressing motions allow the formula to absorb fully without disturbing the film.
5. Seal – follow with a moisturiser at night or a broad-spectrum SPF in the morning.

Who this anua serum suits best

This serum was formulated with a wide range of skin concerns in mind. It is most likely to deliver visible results for:

• K-Beauty fans looking for a clean, reliable serum step with proven Korean actives.
• Anyone whose skin needs deep hydration and brightness without aggressive actives that can cause irritation.
• Shoppers who value full ingredient transparency and an English-labelled product.
• Customers building out the wider Anua range who want a compatible treatment step.

Where the anua serum fits in a K-Beauty routine

This anua serum sits at the treatment stage of a Korean multi-step routine. A typical evening order looks like this:

1. Oil cleanse
2. Water-based cleanse
3. Hydrating toner
4. Treatment step – your anua serum
5. Eye care
6. Moisturiser

In the morning, swap the final moisturiser for a layer of broad-spectrum SPF to protect the hydration you have locked in overnight. For a deeper dive into building a K-Beauty routine, browse our Serums category to see which actives pair well together.
