Product FAQ
Before You Buy
What results can I expect from OSCO products?
OSCO products are specially formulated for modern urban skin, focusing on three key benefits:
- Anti-Pollution Protection: Forms a breathable protective barrier on the skin to block environmental pollutants like PM2.5 and heavy metals, reducing sensitivity and inflammation.
- Skin Barrier Repair: Enriched with precious plant extracts containing Omega fatty acids, it strengthens the skin's defense from within, improving redness and dryness.
- Antioxidant Brightening: Natural high-performance ingredients combat free radicals, brighten the complexion, and fade acne marks.
In simple terms:
- Pollution Defense Serum – Repair + Antioxidant + Protection, all in one
- Pollution Defense Mist – Toning + Hydrating + Makeup setting + Pollution protection, all in one step
- Pollution Detox Mask – Deep cleansing + Soothing hydration
Every product follows our "multi-benefit in one bottle" philosophy, allowing your skin to return to a healthy, stable state in the simplest way possible.
Here's what many of our customers have shared after using our products:
- Reduced redness and sensitivity—skin no longer easily "throws tantrums"
- Breakouts and congestion gradually subside, skin texture becomes smoother
- Acne marks fade, complexion becomes more even and radiant
- Skin barrier strengthens, less affected by environmental factors in daily life
We don't claim to "treat" anything—we simply hope to accompany your skin, in the purest and most natural way, as it gradually returns to its original healthy state.
What skin types are OSCO products suitable for? Can I use them if I don't have acne issues?
OSCO products are suitable for all skin types, including sensitive, dry, combination, and oily skin. Even without acne concerns, daily use helps with antioxidant protection, hydration, and pollution defense, maintaining your skin's healthy and stable condition.
Can people with rosacea or sensitive skin use OSCO products?
Yes. All OSCO products are made with 100% natural ingredients—zero alcohol, zero synthetic fragrances, zero chemical preservatives. The gentle formula is especially suitable for compromised skin. Many of our customers with rosacea or sensitivity have experienced significant improvement after using our products. However, as sensitivity levels vary, we recommend performing a patch test on your inner wrist or behind the ear before first use.
Can pregnant women use OSCO products?
OSCO products are formulated with 100% natural ingredients and meet pregnancy-safe standards. However, as individual conditions and pregnancy circumstances vary, we recommend consulting your healthcare professional before use—this is the safest approach.
Are these products suitable for all seasons?
Yes. OSCO products feature lightweight textures suitable year-round—non-greasy in summer yet sufficiently hydrating in winter, protecting your skin through every season.
Product Usage Questions
Is the Pollution Defense Serum greasy? Will it cause breakouts?
Not at all. Our formula features a lightweight blend of 12 precious plant oils with small molecular structures and high skin affinity, allowing for quick absorption without any greasy residue. It's comfortable even for combination and oily skin types.
In fact, many of our customers have reported fewer breakouts and congestion after incorporating it into their routine.
Do I still need to apply moisturizer after using Pollution Defense Serum?
No, you don't. Our Anti-Pollution Defense Serum is enriched with 12 precious plant oils that provide hydration, repair, and protection all in one—sufficient for your skin's daily needs. Our minimalist skincare philosophy is "multi-benefit in one bottle," freeing your skin from layered product burdens.
Can I use the Pollution Defense Mist before makeup?
Absolutely. Use it as a toning mist after cleansing for hydration; spray another layer after makeup or sunscreen to set your look and create an anti-pollution protective barrier, keeping your skin shielded throughout the day.
Can the products be used around the eye area?
- Pollution Defense Serum and Pollution Defense Mist — Yes, they are gentle enough for the eye area. Simply mist or gently pat the serum around the eyes.
- Pollution Detox Mask — We recommend avoiding the eye area. This mask is designed for deep cleansing to draw out impurities from pores. Since the skin around the eyes is thinner and more delicate, it doesn't require this type of deep cleansing, so it's best to keep the mask away from that area.
Is the "water + oil" two-step routine enough?
Our minimalist skincare philosophy is built on "multi-benefit products"—the serum provides repair and protection, the mist offers instant hydration and makeup setting, and the mask delivers weekly deep cleansing. These three steps cover all your skin's essential needs—no complicated routines required for healthy, radiant skin.
Do I still need to use an additional hydrating mask?
Once you start using the "Mist + Serum" combination, you'll notice that your skin's natural hydration and moisture-locking ability improve significantly.
At that point, using a hydrating mask is no longer a "must-do" emergency fix—it can become an occasional moment of relaxation and self-care, whenever you feel like it.
In other words, you won't need to rely on masks to maintain daily hydration. Give our products a try, and you'll likely find that your dependency on hydrating masks naturally decreases.
It's a feeling of freedom and peace of mind, not burden.
Results & Usage Duration
How long does each product last?
Product longevity depends on usage frequency and amount, but here's a general guide:
- Pollution Defense Serum (15ml): 1-2 months with twice-daily use
- Pollution Defense Mist (100ml): 1-2 months with twice-daily use
- Pollution Detox Mask (30g): ~3 months with 1-2x weekly use
(Usage may vary by skin type and amount used)
How long until I see results?
Natural skincare repair is a gentle "inside-out" process:
- Immediate Sensation (Week 1): Most customers first notice improved skin comfort—better hydration, soothing effect, and quick product absorption without stickiness.
- Initial Results (2-4 weeks): Skin stability gradually improves, redness and congestion decrease, and a natural radiance begins to emerge.
- Long-Term Transformation (Continued Use): The skin barrier becomes healthier and stronger, resistance to environmental pollutants increases, and skin texture becomes smoother and more refined.
We recommend giving your skin at least 28 days (one full skin cycle) for natural ingredients to work their magic. After all, healthy skin is worth the wait.
