Frequently asked questions
FAQYes, this ampoule is considered safe during pregnancy and breastfeeding. It does not contain retinoids, salicylic acid, hydroquinone, or chemical sunscreens that should be avoided during pregnancy. It contains Dipotassium Glycyrrhizate (licorice root derivative) which is generally considered safe for topical use during pregnancy. As always, consult with your healthcare provider if you have specific concerns.
Yes, according to ingredient analysis from SkinSort and other databases, this product is fungal acne (malassezia) safe. It is free from fatty acids, oils, esters, and polysorbates that can feed the malassezia yeast. While it contains Lactobacillus Ferment (a probiotic), this particular ferment is generally well-tolerated by those with fungal acne. However, individual reactions may vary.
Yes, this ampoule is compatible with most active ingredients including retinol, vitamin C, AHA, BHA, and niacinamide. In fact, applying this hydrating ampoule before stronger actives can create a moisture buffer that helps reduce potential irritation. For best results: apply after cleansing and toning, before your active treatments, or use it as a soothing step after exfoliating acids.
This ampoule works well for all skin types but is especially excellent for oily, combination, sensitive, and acne-prone skin due to its lightweight, non-greasy formula. It's also great for dehydrated skin of any type. Those with very dry skin may need to layer it with a richer moisturizer on top. Its humectant-rich formula provides hydration without occlusive heaviness.
You'll notice instant hydration and a dewy, plump appearance immediately after application (within 7 seconds). Improved skin texture and reduced dryness typically appear within 1-2 weeks of consistent use. For longer-term benefits like strengthened skin barrier and sustained moisture retention, expect results in 3-4 weeks of daily AM and PM use.
Apply this ampoule after cleansing and toning, as step 3 in your routine. It goes before serums (if using thicker serums), moisturizer, and sunscreen. The thin-to-thick rule applies: watery products first, then progressively thicker ones. You can apply it on slightly damp skin for enhanced absorption. Use both morning and night.
No, this ampoule has a comedogenic rating of 1 out of 5, meaning it has very low potential to clog pores. It's oil-free, silicone-free, and formulated without heavy occlusive ingredients. The lightweight, watery formula is specifically designed to absorb quickly without leaving pore-clogging residue. It's safe for acne-prone skin.
The product has a PAO (Period After Opening) of 12 months. Once opened, use within one year for optimal efficacy. The unopened shelf life is 30 months from the manufacturing date. Store in a cool, dry place away from direct sunlight to maintain product integrity. The 50ml bottle typically lasts 2-3 months with twice daily use.
Verdict: The Round Lab Birch Juice Ampoule is an excellent lightweight hydrating serum that delivers on its promises. With 10 types of hyaluronic acid and 10,000ppm birch juice, it provides impressive multi-layer hydration in a clean, sensitive-skin-friendly formula. The 7-second absorption and non-sticky finish make it perfect for layering. While the 50ml size may seem small for the price, the quality ingredients and thoughtful formulation justify the investment. Ideal for those seeking a fragrance-free, fungal acne safe, pregnancy safe hydrating ampoule that works for virtually all skin types. A solid K-beauty staple for achieving that coveted glass skin look.
Product Overview
Quick product notes are a great way to check if a product is free from commonly avoided ingredients by skincare enthusiasts. These preferences come about for different reasons depending on the ingredient such as personal experiences, sensitivities, health preferences & etc.
Just because a product is not free from a common preference does not mean it's a bad product! You can make a personal decision whether or not you want to use a product that contains these ingredients or not - click the labels of the preference to read more about them.
Quick Product Notes
Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging «promises» it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.
We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.
Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.
Be smart and use this as just a starting point for you to make more informed and smarter choices and compare it with reviews to see if the product is right for you
Notable Effects & Ingredients
Why are some products great for some people and horrible for others? Well everyone has different skin types and different reactions to the same ingredients.
We've identified a range of ingredients that are commonly regarded as potentially good or bad for those with Dry, Oily/Acne-Prone or Sensitive skin.
A product that contains good or bad ingredients for your skin type doesn't always flat out make the entire product good or bad for your skin. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine your skins reaction.
One of the best ways to use this section is to troubleshoot products you've had bad experiences with in the past. Check if it contains any of the marked ingredients to point out suspect ingredients to avoid in the future!
Ingredients Related to Skin Types
Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.
EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
