Stiva A and Soothing Cream Set

Niosome-Stabilized 2.5% Retinal Cream

Retinal is notoriously unstable under light and heat. This cream encapsulates it in niosome capsules to preserve its potency. A patented niosome complex technology (Patent No. 10-2334706) delivers active retinal deep into the skin texture, and it's a dual-functional cosmetic certified by the Ministry of Food and Drug Safety for both brightening and wrinkle improvement. Enriched with growth factors including EGF, FGF, and IGF, plus L-arginine to balance oil and moisture, it targets firmness and elasticity in one step.

Gentle Formula Safe for Sensitive Skin

The biggest concern for retinal beginners is stinging and irritation. Stiva A Cream has completed both low-irritation and sensitive skin tests at the Korean Institute of Dermatological Sciences and the Korea Skin Research Institute. For the first two weeks, use a small amount (rice grain size) every other night, then gradually increase to nightly use from week three onward. Store in a cool place (3–10°C) to maintain retinal stability for longer.

The Perfect Pairing with a Soothing Hydration Cream

The included Hyalsera Lifting Soothing Cream is designed to be your post-retinal partner, addressing dryness and sensitivity. It features low-molecular-weight hyaluronic acid for moisture replenishment, ceramides to reinforce the moisture barrier, guaiazulene for calming, panthenol for barrier care, and a 14-peptide complex for firmness. Dermatologist-tested and gentle enough for sensitive skin and dehydrated oily skin alike, it can be used morning and night. Apply Stiva A Cream first, then seal it in with Hyalsera to maximize retinal benefits while minimizing irritation.

Evening routine final step, where retinal cream belongs

Use Stiva A Cream as the last step after cleansing, toner, essence, and serum have all been fully absorbed. Because it's a functional cream containing 2.5% retinal, it needs to be applied over a well-hydrated base to minimize irritation and maximize absorption. Hyalsera Soothing Cream is then layered on top of Stiva A Cream to seal in moisture with a protective barrier.

Evening only, morning is for soothing cream alone

Use Stiva A Cream in the evening only. Retinal makes skin more sensitive to UV exposure, so daytime use is not recommended. In the morning, apply Hyalsera Soothing Cream on its own to replenish hydration, and always finish with sunscreen.

Start slow, every other night for the first 2 weeks

If you're new to retinal, start with a rice grain-sized amount (about 2mm) and apply a thin layer to areas of concern. For the first two weeks, use every other night. From week three onward, once your skin has adjusted, you can use it nightly. After applying Stiva A Cream, take about a fingertip's worth of Hyalsera Soothing Cream and gently smooth it over your entire face to lock in moisture without any dryness.

How to customize based on your skin concerns

• For firmness and fine lines: Use Stiva A Cream consistently, and seal with Hyalsera for moisture retention
• For redness and sensitivity: Reduce the amount of Stiva A and apply a generous layer of Hyalsera for calming care
• On dry, tight-feeling days: Apply Hyalsera 1.5 times thicker than usual and use it like a sleeping mask

Important precautions when using retinal

Avoid using high-concentration vitamin C, AHA, or BHA products on the same night. If needed, alternate them on different evenings. If you experience stinging or redness, reduce the amount and frequency, and soothe with Hyalsera. Store Stiva A Cream in a cool place between 3–10°C to maintain retinal stability. Do not use on infants and toddlers under 3 years of age.
