Sinseoncho Calming Anti-Aging Sheet Mask

Gentle Anti-Aging Care with Plant-Based Bakuchiol

If you've been wanting the benefits of retinol without the irritation, this sheet mask deserves your attention. Lassie'el Sinseoncho Calming Anti-Aging Sheet Mask is a wrinkle-improving functional cosmetic formulated with high-purity, plant-derived bakuchiol to support collagen synthesis and help reduce the appearance of fine lines. Unlike retinol, it can be used during the day, and its gentle formula makes it safe even for expectant mothers. The formula is 99% naturally derived, dermatologist-tested for skin irritation, and certified vegan in Korea.

Second-Generation Gel Sheet with 72-Hour Hydration

The patented hydrogel sheet adheres seamlessly to skin, delivering active ingredients evenly across the face. In clinical testing, skin moisture improved by 193.885% immediately after use, and maintained 150.823% hydration even after 72 hours. The moment you apply the sheet, you'll feel an instant cooling effect as skin temperature drops by 8.25°C. Infused with a concentrated, milky serum, it smooths and nourishes dry, depleted skin.

The Right Choice for Sensitive Skin Seeking Firming Care

This mask is ideal for:

Those who want anti-aging results without retinol sensitivity

Sensitive skin prone to redness and heat

Aging skin dealing with both dryness and loss of elasticity

If it's your first time using bakuchiol, start with a short 10-minute application, then gradually increase wear time and frequency as your skin adjusts. Avoid layering with products containing vitamin C, AHA, BHA, or PHA.

Step-by-Step Introduction for First-Time Bakuchiol Users

Use after cleansing and toning to prep your skin. This mask is formulated with a high concentration of bakuchiol, a plant-based retinol alternative, so if you're new to the ingredient, your skin may need time to adjust. Start by patch-testing with the enclosed serum sample to check for any reaction. If you experience no redness or stinging, you're ready to use the mask. For your first application, keep it on for under 10 minutes, and begin with once a week. As your skin builds tolerance, gradually increase both frequency and wear time.

10–20 Minute Application and Essence Absorption

Remove the sheet from the pouch and align it with your eyes and mouth, smoothing it onto your face for seamless adherence. The second-generation gel sheet hugs every contour and delivers an instant cooling sensation. After 10–20 minutes, peel off the mask and gently pat any remaining essence into your skin. The mask is saturated with a rich, milky serum, so you can skip your usual essence step and still enjoy deep hydration.

Morning and Evening Use, Tailored to Your Routine

Unlike retinol, bakuchiol can be used during the day. However, if you're new to the ingredient or have sensitive skin, we recommend starting with evening application. If you do use it in the morning, always follow with broad-spectrum sunscreen to protect your skin. On evenings when your skin feels warm or irritated, this mask works beautifully as a cooling, calming treatment.

Ingredients to Avoid Using Together

Do not use this mask at the same time as products containing:
- Vitamin C (ascorbic acid)
- AHA (exfoliating acids)
- BHA (pore-clearing acids)
- PHA (gentle exfoliating acids)

Combining bakuchiol with these ingredients may cause irritation. If you use both, separate them by time of day or alternate on different days.

Storage and Hygiene

Store in a cool place away from direct sunlight and extreme temperatures. Use immediately after opening, and never reuse a sheet mask. Avoid applying to areas with open wounds, eczema, or active breakouts. If you experience redness, rash, itching, or any other adverse reaction during use, discontinue immediately and consult a dermatologist.
