Kose Retinol Face Mask 6-in-1 — 50-Sheet Jumbo Pack, Japan-Made with Stable Retinol Derivative and Deep Hydration

This high-capacity set from Kose offers daily-ready sheet masks designed to lock in moisture across delicate areas like the corners of the eyes and mouth. Each sheet uses a cushioning, domestically sourced fabric with a weakly acidic pH to help compatibility with skin, and a blend of humectants and proteins — including hyaluronic acid, collagen, elastin, and glycerin — to replenish and plump the skin's surface.

How does this mask reduce the look of dryness-induced fine lines?

The formula combines a stable retinol derivative with moisture-charging ingredients to improve skin plumpness and lessen the visible depth of fine lines caused by dehydration. Rather than aggressive exfoliation, the mask focuses on humectants and structural peptides to support smoother-looking skin over repeated use.

• Stable retinol derivative for targeted appearance improvement without harshness
• Hyaluronic acid and glycerin to attract and hold moisture
• Collagen and elastin to support surface resilience
• Natural moisturizing factors and astaxanthin for antioxidant and hydration support

What is the texture and fit of the sheets like for everyday use?

The sheets are made from thick, Japan-sourced fabric that comfortably conforms to facial contours for even product delivery and reduced slipping. Their cushioning quality helps the serum reach around the eye and mouth areas that often get missed by thinner masks.

• Thicker sheet design for better adherence and reduced evaporation
• Generous serum saturation for full-face coverage
• Easy application and gentle removal suitable for daily routines
• Weakly acidic pH to help maintain skin balance

How many treatments does the jumbo pack provide and how should I include them in my routine?

With 50 sheets, the pack supports frequent use—daily access for several weeks or regular use as a boost in your weekly regimen. Use on clean skin as a hydrating step; follow with your usual moisturizer to seal in the treatment for best results.

• 50 sheets for extended at-home use or travel-friendly portions
• Best used after cleansing and before moisturizing
• Suitable for morning or evening boosting of hydration
• Non-colored and mineral-oil-free formula reduces layering conflicts

Are there ingredient sensitivities or notable exclusions to be aware of?

The mask is formulated without added colorants and without mineral oils, and it uses a gentle, weakly acidic base to minimize disruption to skin balance. As with any retinol-containing derivative, a patch test is recommended if you have very reactive skin or are using other active retinoids.

• No added colorants and no mineral oils
• Includes a mild retinol derivative rather than aggressive retinoids
• Patch testing advised for reactive or retinoid-using skin
• Designed to be gentle yet effective for hydration-focused care

Who is this for: Kose Clear Turn 6-in-1 Retinol Face Mask (50-sheet jumbo pack) suits anyone seeking a convenient, daily-friendly hydration and anti-dryness treatment. It is ideal for people looking to reduce the appearance of dehydration lines, those who prefer thicker sheet masks that stay in place, and anyone who values a large supply for consistent at-home care without extra colorants or mineral oils.
