PRETTYSKIN Pure: Ramelin Active Creams and Pure Jeju Products Explained
PRETTYSKIN's Pure collection splits into two distinct lines: Ramelin Pure Creams (active ingredient-specific 50ml jars) and The Pure Jeju products (Jeju Island plant-based skincare including Sika ampoule, toner, mist, and Vitamin C cream). A cleansing oil completes the range. Each product type targets a different routine step and skin concern.
PRETTYSKIN and the Pure Line Philosophy
PRETTYSKIN is a Korean skincare brand that positions its Pure collection around clean, concentrated active formulations. The "Pure" naming signals a commitment to minimalist formula design: each product highlights one or two key actives rather than using a complex multi-ingredient blend. This makes PRETTYSKIN Pure products easier to layer in a routine without worrying about active conflicts, and it makes the ingredient story transparent - if you need retinol, you buy the Retinol Pure Cream; if you need arbutin brightening, you buy the Arbutin variant.
The Ramelin name on the cream line references a proprietary lamellar (multi-layered membrane) delivery system - the "la-mel-in" structure designed to deliver actives into the upper layers of the stratum corneum more effectively than a standard cream base.
Ramelin Pure Creams: One Active Per Jar
The Ramelin Pure Cream range has five variants, all in 50ml jars. Collagen Pure Cream targets plumping and firmness (hydrolyzed collagen). Retinol Pure Cream delivers vitamin A for cell turnover and anti-aging. Arbutin Pure Cream focuses on brightening through alpha-arbutin's melanin-inhibiting mechanism. Hyaluronic Pure Cream is the hydration-focused option with multiple molecular weights of hyaluronic acid. Lamellin IJIEFF Pure Cream uses a proprietary IJIEFF complex (inflammation-control and barrier support).
Each 50ml jar is a one to three month supply at once-daily use. The 50ml size is also appropriate for a targeted-area application - buying the Arbutin variant for dark spot treatment on cheeks, for example, and using a different cream for the rest of the face.
Ramelin Retinol Pure Cream vs. Arbutin Pure Cream for Anti-Aging and Brightening
Both address skin concerns connected to cell turnover and uneven tone, but through different mechanisms. Retinol Pure Cream stimulates collagen synthesis, speeds cell renewal, and reduces fine lines over time - the changes are structural and build over weeks. It can cause initial purging or irritation in retinol-naive skin. Arbutin Pure Cream inhibits tyrosinase, the enzyme that produces melanin - it brightens existing dark spots and prevents new hyperpigmentation without the irritation risk of retinol. Arbutin is the lower-risk daily-use option; retinol is the stronger anti-aging treatment that requires tolerance building.
For post-acne dark marks (post-inflammatory hyperpigmentation), start with the Arbutin Cream for two to four months while your skin is still building tolerance. Once marks have faded, you can introduce the Retinol Cream for ongoing anti-aging maintenance. The two should not be used in the same routine step - use Arbutin in AM and Retinol at PM if combining.
Lamellin IJIEFF Pure Cream: Barrier Repair and Inflammation Control
The Lamellin IJIEFF Pure Cream uses the IJIEFF complex - a proprietary inflammation-control and barrier-strengthening ingredient set. The Lamellin prefix connects this to the brand's lamellar delivery system. The IJIEFF naming is brand-proprietary (inflammation, joint/junctional, EPIFIX-family molecules) and is positioned for reactive, compromised, or post-procedure skin that needs barrier restoration with anti-inflammatory support.
This is the most functional-treatment cream in the Ramelin range for skin in a stressed state. Use it when your skin is reacting badly to other actives, when you have recently done a strong peel or treatment, or when your barrier feels chronically thin and reactive. It is compatible with sensitive skin and can be used as the primary face cream during a product simplification phase.
The Pure Jeju Sika Line: Centella and Cicaplant from Jeju Island
The Pure Jeju line draws on Jeju Island plant ingredients - the volcanic island in South Korea known for exceptionally clean botanical cultivation conditions. Sika in this context refers to a cicaplant or centella-adjacent healing extract. The Sika 80 Ampoule (50ml) contains 80% Sika concentration - a high-dose treatment ampoule. The Sika 99 Mist (100ml) claims 99% Sika content in a spray-on format for layering or quick application.
The Natural Sika 100 Toner (250ml) is the most economical way to build the Sika concentration into a routine - a full 250ml toner applied morning and night delivers consistent Sika exposure across the routine. Use the ampoule for intensive care periods, the toner for daily maintenance, and the mist for on-the-go hydration and calming during the day.
Pure Jeju Citrus Vita C Cream 52ml: Vitamin C from Jeju Citrus
The Pure Jeju Citrus Vita C Cream (52ml) uses Vitamin C derived from Jeju citrus - the hallabong mandarin orange and citrus varieties grown on the island. Jeju citrus is noted for high ascorbic acid (Vitamin C) concentration due to the mineral-rich volcanic soil. Vitamin C in face cream form provides antioxidant protection against UV-induced free radical damage, brightens existing hyperpigmentation, and supports collagen synthesis. The 52ml size gives approximately two months of daily use.
The cream form of Vitamin C is more stable than water-based serums because the absence of water slows oxidation. Apply it in the morning routine after toner and before SPF - Vitamin C amplifies the antioxidant protection of SPF. If you are using the Arbutin Pure Cream primarily for dark spots, the Vita C Cream makes a compatible AM-use complement (Arbutin in AM, continue with Retinol in PM if needed).
Pure Deep Cleansing Oil 200ml: First Cleanse Step
The Pure Deep Cleansing Oil 200ml is the first-cleanse step in a double-cleansing routine - it dissolves oil-based makeup, sunscreen, and sebum before a second water-based cleanser removes water-soluble impurities. Cleansing oils emulsify when they contact water, turning milky and rinsing off cleanly without leaving an oily residue on skin. At 200ml it provides approximately 50-70 uses at standard first-cleanse amounts.
Apply the cleansing oil to dry skin before wetting - this is critical for oil-based cleansers to dissolve makeup and sunscreen effectively. Massage over the full face for 30-60 seconds, then add a small amount of water to emulsify, and rinse thoroughly. Follow immediately with the second cleanse using a water-based cleanser. The Pure Deep Cleansing Oil is the only PRETTYSKIN Pure product positioned as a cleansing step rather than a treatment product.
How to Stack PRETTYSKIN Pure Products in a Routine
A complete PRETTYSKIN Pure morning routine might look like: Pure Deep Cleansing Oil (if double-cleansing) → water cleanser → Pure Jeju Natural Sika 100 Toner → Pure Jeju Sika 80 Ampoule → Ramelin Arbutin or Hyaluronic Pure Cream → Pure Jeju Citrus Vita C Cream → SPF. The Sika Mist can be used at any point after toner for extra hydration or midday refresh.
An evening routine: water cleanser → toner → Sika 80 Ampoule → Ramelin Retinol or IJIEFF Pure Cream. Do not use the Retinol cream in the morning - retinol is photosensitive and breaks down under UV exposure; always apply it at night. Keep the Arbutin for morning use. The Collagen and Hyaluronic creams are neutral for AM or PM.
FAQ
Frequently asked questions
FAQ
Frequently asked questions
Is the Ramelin Retinol Pure Cream 50ml suitable for someone who has never used retinol before?
The Ramelin Retinol Pure Cream is a cream-format retinol, which is gentler than serum-format retinol at equivalent concentrations because the cream base slows penetration. Beginners can start with two to three nights per week, applying a pea-sized amount as the final step before bed. Watch for dryness, peeling, or redness in the first two weeks - these are normal adjustment signs. If irritation is uncomfortable, reduce to once per week and increase frequency as skin adapts. Build up to nightly use over four to six weeks before expecting full efficacy results.
How long before the Ramelin Arbutin Pure Cream 50ml reduces dark spots?
Alpha-arbutin works by blocking tyrosinase activity, which slows melanin production in spots that are actively darkening. For existing post-acne marks and sun spots, visible fading typically takes eight to twelve weeks of consistent twice-daily use. Spots formed recently (within the last three months) tend to respond faster than older marks. Arbutin prevents new darkening simultaneously, so combine it with daily SPF for best results - UV exposure regenerates the pigmentation the arbutin is suppressing. Do not expect overnight visible change; this is a gradual process.
What is the difference between the Pure Jeju Sika 80 Ampoule 50ml and the Sika 99 Mist 100ml?
The Sika 80 Ampoule (50ml) is a leave-on treatment applied in the serum step - 80% Sika concentration in a thicker, more viscous formula designed to penetrate and calm the skin. It is for twice-daily routine use. The Sika 99 Mist (100ml) is a spray format at 99% concentration - lighter in texture and designed for quick application, either layered during a routine or as an on-the-go calming spray during the day. The mist delivers a thinner amount per application versus the ampoule's serum-like deposit. Use the ampoule as your primary Sika treatment and the mist for convenience top-ups or travel.
How do I know if the Pure Jeju Citrus Vita C Cream 52ml has oxidized?
Fresh Vitamin C in a cream is typically white or very pale yellow. As ascorbic acid oxidizes, it turns yellow, then orange, then brown. If your Vita C Cream has noticeably yellowed or smells slightly sour or off, oxidation has reduced the active Vitamin C concentration significantly. Store the cream in a cool, dark location (not in a steamy bathroom), keep the lid tightly closed between uses, and use within 12 months of opening (the PAO label on the jar confirms this). The cream format is more stable than serum because the absence of water slows the oxidation process.
Can I use the Pure Deep Cleansing Oil 200ml if I do not wear makeup?
Yes. Even without makeup, daily sunscreen and sebum accumulate on the skin surface throughout the day. Sunscreen in particular contains UV filters that are oil-soluble and difficult to remove with a water-based cleanser alone. The Pure Deep Cleansing Oil effectively removes sunscreen and daily sebum in about 60 seconds of massage on dry skin. If you do not wear SPF or produce minimal sebum, you may find a single water-based cleanse sufficient - but if you wear any SPF above SPF 30, a cleansing oil first step is worth the extra minute.
Can I use the Lamellin IJIEFF Pure Cream and the Retinol Pure Cream in the same routine?
Yes, but in different routine steps. Use the Retinol Pure Cream as the active treatment at night (after toner and ampoule), then apply the IJIEFF Cream on top as the final moisturizer to buffer the retinol and support barrier function. This is a common approach for people building retinol tolerance - the IJIEFF's anti-inflammatory and barrier-repair properties reduce retinol-induced irritation. Do not mix them in your palm; apply in layers and allow each to absorb partially before the next. Do not use Retinol in the morning.
What is the Sika ingredient in the Pure Jeju Natural Sika 100 Toner 250ml?
Sika in PRETTYSKIN's Pure Jeju line refers to a cicaplant or centella asiatica-related complex sourced from Jeju Island plants. Centella asiatica (tiger grass) is a well-documented wound-healing and barrier-repairing botanical in Korean skincare. The "Sika" naming is PRETTYSKIN's brand shorthand for this Jeju-grown centella extract. The Natural Sika 100 Toner at 250ml delivers this ingredient in a toner step - high water content with concentrated Sika extract for first-step absorption into cleaned skin. At 100 in the name, it implies a high concentration formula.
Is the Ramelin Collagen Pure Cream 50ml the same as a lifting or firming cream?
The Ramelin Collagen Pure Cream is a moisturizer with hydrolyzed collagen as its key conditioning ingredient. Surface-applied collagen provides temporary plumping and smoothing of fine lines rather than structural lifting - the collagen molecules are too large to penetrate to the dermis where native collagen synthesis occurs. The immediate visible effect is a smoother, more supple skin surface. For visible structural firmness or lifting changes, you need products with retinol, peptides, or IJIEFF-type actives at therapeutic concentrations used consistently over months. Use the Collagen Cream if you want the surface plumping effect; pair it with the Retinol Pure Cream at night if you want the longer-term anti-aging structural work.
Are PRETTYSKIN Pure Jeju products made with genuine Jeju Island ingredients?
PRETTYSKIN's Pure Jeju line is manufactured in Korea with Jeju Island botanical sourcing. Jeju Island is a designated UNESCO Natural Heritage site and a major source of Korean cosmetic botanicals including green tea, citrus, and centella varieties. All PRETTYSKIN Pure Jeju products on skinsli are imported from Korea through authorized distribution channels. The Korean-language ingredient list on the outer packaging names the Jeju botanical source. Batch codes on the base decode to manufacture dates via CheckFresh.com; standard shelf life for opened products is 12 months.
Can I use the Ramelin Hyaluronic Pure Cream 50ml over the Pure Jeju Sika 80 Ampoule?
Yes. This is a natural layering combination: apply the Sika 80 Ampoule as the serum step after toning, allow it to absorb for 1-2 minutes, then apply the Hyaluronic Pure Cream as the moisturizer step. The ampoule delivers the Sika active deep into the skin surface; the Hyaluronic Cream seals in moisture and provides multi-weight hyaluronic acid hydration on top. Both products are calming and barrier-supportive, so they are compatible without any active conflict risk. This combination suits reactive, dehydrated, or post-treatment skin particularly well.
