Frequently asked questions
FAQYes, this serum is generally considered safe during pregnancy and breastfeeding. It contains no retinoids, salicylic acid, hydroquinone, or chemical sunscreens. Galactomyces Ferment Filtrate and Niacinamide at 2% are both considered safe topical ingredients during pregnancy. However, always consult with your healthcare provider before adding new skincare products to your routine during pregnancy or breastfeeding.
No, this product is NOT safe for fungal acne. Galactomyces Ferment Filtrate is a yeast-derived ingredient that can aggravate Malassezia folliculitis (fungal acne). Studies show that galactomyces activates aryl hydrocarbon receptors (AhR), which people with malassezia-associated conditions have heightened sensitivity to. If you have or are prone to fungal acne, avoid this product and look for fungal-acne-safe alternatives.
Yes, this serum pairs well with most actives. Galactomyces and 2% Niacinamide are gentle and non-irritating. You can use it with: Retinol (apply serum first, retinol after), Vitamin C (safe to layer or use at different times of day), AHA/BHA (use acids first, then this serum). The serum can help soothe and hydrate skin when using stronger actives. Start slowly when combining and watch for any irritation.
This serum works well for most skin types, but is especially excellent for: Oily and combination skin (lightweight, sebum-regulating), Dull skin needing radiance boost, Those with enlarged pores and uneven texture, Sensitive skin (fragrance-free, minimal ingredients). It's good for dry skin as a hydrating layer but should be followed by a richer moisturizer. Avoid if you have fungal acne.
Results timeline varies by concern: Immediate (Day 1): Hydration boost and dewy glow. 1-2 weeks: Improved skin texture and softness. 4-6 weeks: Visible pore refinement and brightness improvement. 8-12 weeks: Significant improvement in skin tone, dark spots, and overall radiance.

Apply 2-3 drops to face and neck after cleansing and toning. Pat gently until absorbed. Wait 30-60 seconds before next product. Can be used both morning and night.
No, this serum has a comedogenic rating of 0/5 and will not clog pores. All ingredients (Galactomyces Ferment Filtrate, Glycerin, Niacinamide, 1,2-Hexanediol, Sodium Hyaluronate) have comedogenic ratings of 0. The formula is also oil-free and silicone-free. It's suitable for acne-prone skin types, though those with fungal acne should still avoid due to the fermented ingredient.
The serum has a PAO (Period After Opening) of 12 months. Store in a cool, dry place away from direct sunlight. The 30ml bottle typically lasts 4-8 weeks with twice-daily use (2-3 drops per application). Check the manufacturing date on the product sticker. Discard if you notice any changes in color, smell, or texture.
Verdict: Cos de Baha Galactomyces 94% Serum delivers impressive results at an unbeatable price point. With 94% fermented filtrate (the same hero ingredient as $185 SK-II) and a clean 5-ingredient formula, it's a smart choice for those seeking radiance, hydration, and pore refinement without the luxury price tag. The main limitations are the small bottle size and unsuitability for fungal acne sufferers. For everyone else looking to try fermented skincare, this is an excellent, science-backed starting point that punches well above its weight class.
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.
