Rosyroy

Rosyroy is a Korean cosmetics brand that built its identity around PDRN (polydeoxyribonucleotide), an ingredient extracted from salmon DNA that is used in medical aesthetics for wound healing and tissue regeneration. In skincare and haircare, PDRN is used for its cell signaling and repair-stimulating properties - supporting hair shaft integrity, scalp cell renewal, and skin regeneration.

PDRN is one of the more expensive actives in Korean professional skincare. Its presence in a consumer haircare brand like Rosyroy brings a clinical-grade ingredient into daily-use products at accessible price points. The brand pairs PDRN with complementary actives - caffeine for scalp stimulation, tea tree for clarifying - to build a functional haircare and skin treatment range.

The Flower PDRN Essential Hair Oil is available in two sizes at skinsli.com: 30ml and 50ml. The "Flower" designation refers to the botanical base ingredient alongside PDRN - likely floral oil extracts that contribute fragrance and additional conditioning properties. The hair oil is a leave-in treatment for the hair mid-lengths and ends, applied after washing to reduce frizz, add shine, and deliver PDRN to the hair surface for repair support.

At 30ml the oil is a trial or travel size; at 50ml it is the standard daily-use size. Use 2-3 drops pressed between palms and smoothed over towel-dried or dry hair. Avoid applying directly to the roots to prevent scalp buildup. The oil can also be applied as a pre-shampoo treatment on the ends, left for 20-30 minutes before washing, for an intensive conditioning session.

The PDRN Protein Polish Parfum is a leave-in hair treatment that combines PDRN protein polish with a perfume function - a category popular in Korean haircare where the treatment product also delivers long-lasting fragrance to the hair. Four scents are available at skinsli.com: 02 Claudi Blossom (floral), 03 Vanilla Cotton Candy (warm sweet), 04 Attum Reminiscence (a fall-inspired blend), and 05 Fruity Picnic (fruity and fresh).

At 50ml each, the parfums are generously sized for daily use. Apply to damp or dry hair as a styling finish - a few sprays or pumps distributed through hair lengths. The protein component in the formula provides light strengthening alongside the scent. The multi-scent range allows you to match the fragrance to your preference or season without changing the core treatment function.

The Caffeine 5 Scalpel Ampoule is a concentrated scalp treatment using caffeine as its lead active. Caffeine is a well-studied ingredient in scalp care: it penetrates the follicle and inhibits the enzyme DHT (dihydrotestosterone) activity, which is associated with hair thinning and follicle miniaturization. At 5% concentration this is a meaningful dose - comparable to concentrations used in published studies on topical caffeine for hair density support.

The 18ml ampoule is applied directly to the scalp in targeted small doses - typically 1ml per use applied with a dropper along the parting or thinning zones. Massage in and leave on without rinsing; the formula absorbs into the scalp. Use daily for 8-12 weeks to assess results. Caffeine-based scalp ampoules are generally well-tolerated and can be used alongside regular shampoo routines.

The Lipina 12 Ampoule at 18ml is a concentrated treatment with "12" likely referencing the number of active ingredients or a concentration percentage in the formula. "Lipina" suggests a lipid or nourishing focus - possibly targeting fine, sparse, or thinning lashes, brows, or hair. The 18ml ampoule format is consistent with a targeted scalp or hair treatment designed for precise application in small doses. Apply with the included dropper or applicator to the target area as directed on the packaging.

The Halo Gel Boosting Moisturizer at 55ml is Rosyroy's facial skincare product in the range. A gel moisturizer has a water-heavy, lightweight texture that absorbs quickly without a greasy or heavy residue - suited for oily, combination, and normal skin types. "Boosting" suggests the gel also delivers active ingredients beyond basic hydration, potentially including PDRN or other regenerative actives consistent with the Rosyroy brand approach.

Apply the gel after cleansing and toning, before any heavier cream or SPF. The 55ml size provides approximately two to three months of daily use in a single-application routine. Gel moisturizers sit well under sunscreen in the morning and can be used morning and evening for those who prefer a lighter finish at night.

The 80 True Tea Tree Filling Pads are pre-soaked exfoliating and clarifying pads with tea tree oil as the lead active. Tea tree is a well-established antimicrobial and anti-inflammatory botanical used in skincare for blemish-prone and oily skin. At 80 pads per pack, this is roughly a two-to-three month supply at daily use. Each pad is soaked in a formula that combines mild exfoliation (likely BHA or AHA) with tea tree's clarifying properties.

Use one pad after cleansing, wiping across the face and neck in gentle strokes, and leave the residue on skin to absorb. The "filling" in the name suggests the pads also deliver hydrating or pore-blurring ingredients alongside the clarifying actives - a common combination in Korean exfoliating pad formulas. Start with every other evening if your skin is new to regular exfoliation.

For a combined hair and skin routine using Rosyroy: on scalp treatment days, apply the Caffeine 5 Scalpel Ampoule to the scalp after washing and drying. Follow with the Flower PDRN Hair Oil on hair ends. Use the PDRN Protein Polish Parfum after styling as a finishing and fragrance step.

For skin: use the 80 True Tea Tree Filling Pads in the evening after cleansing (2-3 times per week), and apply the Halo Gel Boosting Moisturizer as a daily moisturizer step morning and evening. The Lipina Ampoule is a targeted treatment - apply as directed to thinning or sparse areas rather than all-over.
