Where it fits in your routine
ROUTINEApply after essence/toner and before heavier serums or moisturizer. Can also be used as an overnight sleeping mask by applying a thicker layer as the final step in your PM routine.
How to use
HOW TO USECleanse & Prep
Start with clean, freshly cleansed skin. Apply your toner and/or essence first to prep skin for better absorption.
Apply Serum
Scoop a pea-sized amount with the included spatula. Dot onto forehead, cheeks, chin, and nose.
Massage & Pat
Gently massage in circular motions until fully absorbed. The jelly texture will melt into skin leaving a dewy finish.
Follow Up
Continue with moisturizer and sunscreen (AM). For overnight mask use, apply a generous layer as your final step (PM).

Skin type compatibility
SKIN TYPESNiacinamide helps regulate sebum. Jelly texture may feel slightly rich for very oily skin; use sparingly in summer.
Glycerin, hyaluronic acid, and the bouncy texture provide excellent hydration. Layer with moisturizer for best results.
Balances well across different face zones. Niacinamide addresses oily T-zone while hydrating dry areas.
Fragrance-free with soothing panthenol. Patch test first as ferments may irritate some sensitive skin types.
Low comedogenic rating, but NOT fungal acne safe. Good for hormonal/bacterial acne; avoid if you have fungal acne.
Ideal target audience. Collagen complex, peptides, and multiple vitamins address aging concerns comprehensively.

Similar niacinamide-focused formula with 60% propolis. More affordable but different target - focuses on acne/sebum control rather than anti-aging collagen boost.

Frequently asked questions
FAQUse with caution. While most ingredients are pregnancy-safe (niacinamide, vitamin C, hyaluronic acid), this serum contains Arbutin, which is a hydroquinone precursor. Some dermatologists recommend avoiding arbutin during pregnancy due to limited safety data. Consult your healthcare provider before use if you are pregnant or breastfeeding.
No, this serum is NOT fungal acne safe. It contains Saccharomyces/Rice Ferment Filtrate (a fermented ingredient), Polyglyceryl-10 Myristate, and Polyglyceryl-10 Laurate (esters). These ingredients can feed Malassezia yeast and potentially worsen fungal acne. If you have fungal acne, consider alternatives like COSRX 6 Peptide Skin Booster Serum instead.
Yes! This serum layers well with most actives. It already contains multiple forms of vitamin C, so it pairs well with additional vitamin C products. For retinol: use the serum first, let it absorb, then apply retinol. For AHA/BHA: use acids first on clean skin, wait 15-20 minutes, then apply this serum. The niacinamide in this formula can help buffer potential irritation from strong actives.
This serum is best suited for normal, dry, combination, and mature skin types. It excels for those concerned with early signs of aging, loss of elasticity, enlarged pores, and dull skin. While it works for oily skin too (thanks to niacinamide), the rich jelly texture may feel heavy in very humid conditions. Not recommended for those with fungal acne.
Immediate: Hydration boost and dewy glow visible from first use. Week 2-4: Smoother texture and refined pores. Week 6-8: Visible brightening and more even skin tone. Week 12+: Improved firmness and elasticity from collagen-boosting ingredients. Consistency is key—use morning and night for best results.
Apply after cleansing, toner, and essence (if using), but before heavier serums, moisturizer, and sunscreen. The rule of thumb is thinnest to thickest consistency. This serum has a jelly-gel texture, so it goes after watery products. For PM use, it can also be applied as the final step as an overnight sleeping mask—just use a thicker layer.
This serum has a low comedogenic rating of 1/5. It does not contain heavy oils, silicones, or known pore-clogging ingredients. The niacinamide actually helps regulate sebum production and minimize pore appearance. However, if you have fungal acne (not regular comedonal acne), this product is not suitable due to fermented ingredients and esters.
The Period After Opening (PAO) is 12 months. With twice-daily use of a pea-sized amount, the 50g jar typically lasts 2-3 months. Store in a cool, dry place away from direct sunlight. Always use the included spatula rather than fingers to maintain hygiene and extend shelf life. Refrigeration is optional but can provide a soothing, cooling effect.
Verdict: Arencia Red Smoothie Serum 30 is a well-formulated K-beauty anti-aging serum that delivers on its promises of hydration, brightening, and improved elasticity. The unique 30% Red Collagen Complex combined with niacinamide, peptides, and five forms of vitamin C makes it a comprehensive treatment for early signs of aging. The luxurious jelly texture is a standout feature that makes application feel spa-like. However, it loses points for not being fungal acne safe and containing arbutin that may concern pregnant users. Best for those with dry to combination skin looking for a multi-tasking anti-aging serum with a focus on collagen support and brightening. Give it 8-12 weeks of consistent use to see the full benefits.
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

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.

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.
