SEOUL 1988 Eye Cream : Retinal Liposome 4% + Fermented Bean

4% Retinal Eye Cream Stabilized with Liposome Technology

This eye cream delivers a high 4% concentration of retinal, which works up to 11 times faster than retinol. We've applied liposome technology to this naturally unstable ingredient to enhance both its stability and absorption. Once delivered safely into the deeper layers of skin, it helps stimulate collagen production, targets the appearance of wrinkles and hyperpigmentation, and supports skin firmness. While designed for the eye area, it can also be used on deeper wrinkles and enlarged pores anywhere on the face.

Non-Irritating Result in 24-Hour Patch Test

In a human application test conducted by the Korean Dermatology Research Institute, this formula was classified as non-irritating after a 24-hour occlusive patch test. If you've been drawn to the power of retinal but hesitant about irritation, this is formulated with your concerns in mind. The gentle formula excludes common allergens, harsh alcohols, fragrance, parabens, silicones, and artificial colorants.

Multi-Layered Care with Fermented Ingredients and Peptides

Five fermented ingredients—including fermented soybean extract, ginseng, rice, Job's tears, and potato—deliver antioxidant support and hydration. Bakuchiol, vitamin C, vitamin E, and three peptides work together to support collagen synthesis and enhance skin firmness. Five root extracts—burdock, yam, cnidium, rehmannia, and peony—contribute anti-inflammatory and antioxidant benefits.

• If deep wrinkles are a visible concern
• If you want to improve the look of sagging pores and rough texture
• If you have sensitive skin and need a gentle retinal formula

If you're new to this product, ease in gradually: use twice a week for the first 1–2 weeks, every other night during weeks 3–4, then nightly from week 5 onward. Apply a pea-sized amount as the final step of your nighttime routine, smoothing gently over the skin.

Use in the evening as the final step of your skincare routine

Retinal is sensitive to sunlight, so evening use is essential. After completing your cleanser → toner → essence → serum routine, apply this eye cream as the last step. You can also use it on areas beyond the eye contour where fine lines or enlarged pores are a concern.

Night use is the rule. If used during the day, always pair with SPF

Retinal can oxidize when exposed to UV rays, so nighttime application is recommended. If you must use it during the day, always follow with sunscreen. For your morning routine, focus on vitamin C serums or hydrating products, and save your retinal care for the evening for best results.

A pea-sized amount, applied using the sandwich method

The right amount is about the size of a pea. Using more won't boost results and may actually cause irritation, so keep it minimal. If you have sensitive skin, try the sandwich method:

• Apply a lightweight moisturizer first as a thin base layer
• Gently pat the eye cream on top
• Seal it in with a richer moisturizer as the final step

Always apply to completely dry skin to minimize irritation, so wait until your toner is fully absorbed before application.

Routine pairings based on your skin concerns

If firmness and fine lines are your focus, layer with a serum containing bakuchiol or peptides for added synergy. If uneven tone or dullness is your concern, use a vitamin C serum in the morning and this eye cream at night to separate actives by time of day. On particularly dry days, finish with a ceramide cream to support your skin barrier.

Retinal adjustment period and precautions

If you're new to retinal, your skin will need time to adjust.

• Weeks 1–2: Use twice a week
• Weeks 3–4: Use every other night
• Week 5 onward: Use nightly

A patch test is recommended before first use. Store in a cool place away from direct sunlight. Refrigeration can help maintain stability even longer. Avoid use during pregnancy and breastfeeding. If irritation occurs, discontinue use and consult a dermatologist.
