Frequently asked questions

FAQ

Yes! This serum is completely safe for use during pregnancy and breastfeeding. It contains no retinoids, salicylic acid, hydroquinone, chemical sunscreens, or any other ingredients flagged as concerning during pregnancy. All ingredients are EWG Green-rated for safety.

Yes! This serum is fungal acne safe. It does not contain fermented ingredients, fatty acids (C11-C24), fatty acid esters, polysorbates, or other ingredients that can feed malassezia yeast. It's been verified as FA-safe by ingredient analysis tools like SkinSort.

Yes! This serum is gentle and hydrating, making it an excellent companion to active ingredients. Apply acids or vitamin C first, let absorb, then use this serum to hydrate and soothe. For retinol, use this serum before retinol to buffer, or after to calm any irritation. The Centella and Hyaluronic Acid help counteract dryness from actives.

This serum works excellently for all skin types but is particularly ideal for: oily skin (lightweight, non-greasy), sensitive skin (0.00 irritation rating), acne-prone skin (non-comedogenic, FA-safe), and combination skin (balances without overwhelming). Dry skin types may want to layer a richer moisturizer on top.

You'll feel instant hydration and a subtle cooling sensation immediately. Improved skin texture typically appears within 1-2 weeks. The coveted "glass skin" glow and reduced redness usually become visible around 3-4 weeks of consistent use. Full barrier-strengthening benefits develop over 6-8 weeks.

Apply after cleansing and toning, before heavier serums and moisturizer. The order is: Cleanser → Toner → This Serum → Other serums (if any) → Moisturizer → Sunscreen (AM). For best results, apply to slightly damp skin to lock in moisture.

No! This serum has a comedogenic rating of 1/5 (very low). It contains no pore-clogging oils, heavy silicones, or comedogenic ingredients. The lightweight watery-gel texture absorbs quickly without leaving residue that could trap dirt or sebum. It's specifically formulated to be safe for acne-prone skin.

The serum has a PAO (Period After Opening) of 12 months. Once opened, use within one year for best efficacy. The dropper bottle helps minimize contamination and oxidation. Store in a cool, dry place away from direct sunlight to maintain freshness.

— Skincarisma verdict
4.4 / 5 ★★★★☆

Verdict: MIMU MIMU Cooling Calming Serum is an excellent choice for those seeking a lightweight, clean-formula hydrating serum with soothing benefits. Its standout features are the 10-type Hyaluronic Acid complex for multi-layer hydration, pregnancy and fungal acne safety, and EWG All Green certification. While the cooling sensation is subtler than some expect, the serum delivers on its hydration and calming promises. Best suited for sensitive, oily, combination, and acne-prone skin types looking for a K-beauty essential that fits into any routine. For the price point, it offers good value with its clinical-grade gentleness and thoughtful formulation.

question
lightbulb What are Notable Effects & Ingredients?

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.

muscle Pro Tip Alert!

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

question
lightbulb What are Ingredients Related to Skin Type?

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.

muscle Pro Tip Alert!

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!

question
lightbulb What is the Ingredient Safety Breakdown?

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.

muscle Pro Tip Alert!

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.
