Frequently asked questions

FAQ

Yes! This serum is considered safe for use during pregnancy and breastfeeding. It's free from retinoids, salicylic acid, hydroquinone, and chemical sunscreens - all ingredients commonly avoided during pregnancy. The formula is dermatologist tested and hypoallergenic, making it a great choice for expectant and nursing mothers looking for anti-aging skincare.

No, this product is not fungal acne safe. It contains Caprylic/Capric Triglyceride (a fatty acid ester) and Lactobacillus Ferment (a ferment), both of which can potentially feed Malassezia yeast and worsen fungal acne. If you have fungal acne, consider alternatives like Tower 28 SOS Spray which has a minimal, FA-safe ingredient list.

Yes! This serum plays well with most active ingredients. Its gentle, hydrating formula can help buffer the irritation from retinol or acids. Apply the serum first to provide hydration, let it absorb, then follow with your actives. The probiotic and soothing artemisia may even help calm any irritation from stronger treatments.

This serum works well for most skin types, but is especially excellent for dry, combination, sensitive, and mature skin. It's hypoallergenic and non-acnegenic, making it suitable for acne-prone skin (except fungal acne). Oily skin types may enjoy the lightweight formula but should note it provides a dewy finish that some may not prefer.

Hydration benefits are immediate - you'll notice plumper, dewier skin right away. For firming and anti-aging results, clinical studies showed significant improvement in skin moisture and firmness after 4 weeks of consistent use. 100% of participants showed improved moisture and 90% showed improved firmness after 4 weeks in clinical testing.

Apply after cleansing (and toner if you use one) but before heavier serums and moisturizer. Use on clean, dry skin morning and night. It can also be spritzed throughout the day over makeup for a refreshing hydration boost, or layered between other skincare products to help them absorb better.

No, this serum has a low comedogenic rating of 1/5 and is clinically tested as non-acnegenic. The lightweight, water-based formula contains no oils, waxes, or heavy emulsifiers that typically clog pores. Ingredients absorb directly into skin without leaving a pore-blocking barrier.

The product has a PAO (Period After Opening) of 12 months. Store in a cool, dry place away from direct sunlight to maintain freshness. The glass bottle helps protect the formula from degradation. Most users find the 100ml bottle lasts 2-3 months with twice-daily use.

— Skincarisma verdict
4.5 / 5 ★★★★★

Verdict: The Kosas Plump + Juicy Vegan Collagen Spray-On Serum is an excellent choice for those seeking a quick, effortless hydration step with anti-aging benefits. The innovative spray format, clean vegan formula, and clinically-proven results make it stand out in the crowded face mist category. It's particularly impressive for sensitive and mature skin types, with 100% of clinical study participants showing improved moisture. The main drawbacks are the premium price point and its unsuitability for fungal acne. If you value clean beauty, convenience, and visible firming results - and don't have fungal acne - this is a worthwhile investment in your skincare routine.

lightbulb What are Quick Product Notes?

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.

muscle Pro Tip Alert!

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.
