Frequently asked questions

FAQ

Yes, this serum is considered safe for use during pregnancy and breastfeeding. It contains no retinoids, salicylic acid, hydroquinone, chemical sunscreens, or other ingredients typically contraindicated during pregnancy. The formula focuses on gentle, nourishing ingredients like mushroom extracts, niacinamide, and probiotics. However, always consult with your healthcare provider before adding new skincare products during pregnancy.

No, this serum is NOT fungal acne safe. It contains multiple fermented ingredients including Lactobacillus Ferment, Saccharomyces Ferment, Lactococcus Ferment Lysate, Streptococcus Thermophilus Ferment, and Bacillus Ferment. Fermented ingredients can potentially feed Malassezia yeast and worsen fungal acne. If you have malassezia folliculitis, consider alternatives like IUNIK Beta Glucan Power Moisture Serum which is fungal acne safe.

Yes! This serum is an excellent companion to active ingredients. The barrier-strengthening properties help protect skin from irritation caused by potent actives like retinol, vitamin C, AHAs, and BHAs. Apply the Reishi serum before heavier actives, or use it on alternating nights with your strongest treatments. The niacinamide and probiotics help calm and repair skin while you use other active ingredients.

This serum works well for most skin types, but is particularly excellent for dry, combination, and sensitive skin. It's also great for anyone with a compromised skin barrier, those recovering from over-exfoliation, or anyone who uses active ingredients and needs barrier support. Oily skin types can use it as a nighttime serum. However, those with fungal acne should avoid it due to the fermented ingredients.

Most users notice improved hydration within the first week. Barrier strengthening and reduced sensitivity typically become apparent after 2-3 weeks of consistent use. For visible improvements in overall skin health, radiance, and texture, expect to use the product for 4-8 weeks. This is a supporting serum that works best as part of a consistent routine rather than providing overnight dramatic results.

Apply this serum after cleansing and toning, before heavier serums, treatments, and moisturizer. The typical order is: Cleanser → Toner → VEGREEN Reishi Serum → Treatment serums (vitamin C, retinol) → Moisturizer → Sunscreen (AM). Its lightweight, watery texture absorbs quickly and layers well under other products. You can use it both morning and evening.

This serum has a low comedogenic rating of 1/5. It contains no heavy oils, silicones, or known pore-clogging ingredients. The lightweight, watery formula absorbs quickly without leaving residue. It's suitable for acne-prone skin (except fungal acne). The niacinamide may even help regulate oil production and minimize pore appearance over time.

The Period After Opening (PAO) is 12 months. Once opened, use within one year for optimal effectiveness. Store in a cool, dry place away from direct sunlight. The pump packaging helps protect the formula from contamination and oxidation. With twice-daily use of 1-2 pumps, a 50ml bottle typically lasts 2-3 months.

— Skincarisma verdict
4.3 / 5 ★★★★☆

Verdict: VEGREEN Skin Barrier Reishi Serum is an excellent value-driven K-beauty serum that delivers on its barrier repair and hydration promises. The 65% Reishi mushroom concentration and 5-ferment probiotic blend make it a standout for strengthening compromised skin barriers. It's a worthy affordable alternative to luxury mushroom serums like Origins Mega-Mushroom at a fraction of the price. The main drawbacks are its unsuitability for fungal acne sufferers and the somewhat small bottle size. Perfect for minimalist routines seeking gentle, effective hydration and barrier support—especially during pregnancy or while using active ingredients.

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.
