Frequently asked questions
FAQYes, this serum is considered safe for pregnancy and breastfeeding. It contains no retinoids, salicylic acid, hydroquinone, or chemical sunscreens – the main ingredients to avoid during pregnancy. The formula uses gentle, plant-based ingredients. However, always consult your healthcare provider before introducing new skincare products during pregnancy or nursing.
No, this serum is NOT fungal acne safe. It contains several ingredients that may feed malassezia yeast, including: Cetyl Ethylhexanoate, Sorbitan Stearate, Sorbitan Sesquioleate, Sucrose Cocoate, and fermented ingredients. If you have pityrosporum folliculitis, consider the simpler Mixsoon Bean Essence instead, which is fungal acne safe.
Yes, this serum can be used with most actives. For retinol: apply the serum first, wait 30 minutes, then apply retinol. The hydrating properties can help minimize retinol irritation. For Vitamin C: use vitamin C in the morning and this serum can be used AM or PM. For AHA/BHA: apply acids first on clean skin, wait for absorption, then layer this serum on top for added hydration.
This serum works best for dry, combination, and normal skin types. It's excellent for those seeking hydration, brightening, and anti-aging benefits. Oily skin types can use it but may prefer the lighter Bean Essence. It's suitable for sensitive skin (fragrance-free) but patch test if very reactive. NOT recommended for fungal acne-prone skin.
Hydration results are immediate – skin feels more supple from the first use. Improved texture and smoother skin typically appears within 2-4 weeks of consistent use. Brightening and firming benefits become noticeable around 6-8 weeks. For long-term anti-aging benefits, continued use for 12+ weeks is recommended.
Apply after cleansing and toning, but before heavier creams and sunscreen. The order is: Cleanser → Toner → Essence (optional) → This Serum → Moisturizer → Sunscreen (AM). Use 2-3 pumps and gently pat until absorbed. Can be used both morning and evening.
This serum has a low comedogenic rating of 1/5 and is designed not to clog pores. The lightweight, fast-absorbing formula is suitable for most skin types including acne-prone skin. However, as with any skincare product, individual reactions may vary. If you're prone to breakouts, patch test first and introduce gradually into your routine.
The serum has a PAO (Period After Opening) of 12 months. A 50ml bottle typically lasts 4-6 months with twice-daily use of 2-3 pumps per application. If using once daily, expect 8-10 months of use. Store in a cool, dry place away from direct sunlight. Refrigeration is optional but can extend freshness.
Verdict: The Mixsoon Soybean Milk Serum is an excellent K-beauty serum that delivers on its promises of deep hydration, brightening, and firming. The 72-hour fermented soybean extract, combined with peptides, ceramides, and vegan collagen, creates a comprehensive formula that addresses multiple skin concerns. It's particularly well-suited for dry to combination skin seeking anti-aging benefits without harsh actives. The only notable drawback is that it's not fungal acne safe due to fermented ingredients and esters. At around $25 for 50ml, it offers solid value compared to luxury alternatives like SK-II while providing a more comprehensive formula than budget options.
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.
