Stiva A and Soothing Cream Set

Retinal 2.5% Cream Stabilized with Niosome Technology

A cream that encapsulates retinal—which easily breaks down when exposed to light and heat—in niosome capsules to enhance its stability. The patented niosome complex (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. Formulated with Moringa Peptide Complex alongside EGF (Epidermal Growth Factor), FGF (Fibroblast Growth Factor), IGF (Insulin-like Growth Factor), and L-Arginine (for oil-moisture balance) to support firming care. Niacinamide (for tone correction) and adenosine (for wrinkle improvement) help transform a dull complexion into one that's brighter and more luminous.

Clinically Proven Gentle Formula, Even for Sensitive Skin

Completed a low-irritation skin test (30 participants) at the Korean Dermatology Research Institute and a sensitive skin irritation test (32 participants) at the Korea Skin Science Institute. Propanediol and trehalose add a layer of hydration to minimize the dryness typically associated with retinal.

Usage Guide for Retinal Beginners

For the first two weeks, apply every other evening—use a millet seed-sized amount (approximately 2mm) and spread thinly over areas of concern. From week three onward, you can use a rice grain-sized amount (approximately 4mm) every evening across the entire face. If you experience tingling or redness, reduce the amount and frequency, and pair with a soothing, hydrating moisturizer.

• Always apply sunscreen the following morning
• Avoid using simultaneously with high-concentration vitamin C, scrubs, or AHA/BHA products—alternate on different days instead
• Recommended to store in a cool place at 3–10°C

Use as the final step in your evening routine

Stiva A Cream is a functional product containing 2.5% retinal, designed to be used as the last step in your skincare routine. After cleansing, prep your skin with toner and essence, then allow your hydrating serum to absorb fully before applying Stiva A Cream. If you're using it alongside Hyalsera Soothing Cream, apply Stiva A Cream first, then seal everything in with the Soothing Cream as your final moisture layer.

Evening use only, start every other night

Due to the nature of retinal, use this product only in your evening routine. For the first two weeks, apply every other night to monitor how your skin responds. From week three onward, you can gradually increase to nightly use. Avoid morning application, and always apply sunscreen the morning after using retinal to protect your skin.

Start with a millet-seed amount and build up gradually

Begin with approximately 2mm (about the size of a millet seed) and gently spread a thin layer over areas of concern. Once your skin has adjusted, increase to 4mm (about the size of a grain of rice) and apply smoothly across the entire face. The skin around the eyes and lips is thinner, so apply with a light, tapping motion in these areas.

Recommended combinations by skin type

• Dry and sensitive skin: After Stiva A Cream, apply a generous layer of Hyalsera Soothing Cream to prevent moisture loss
• Skin needing firmness and tone care: Formulated with niacinamide and adenosine to target brightening and wrinkle improvement simultaneously
• First-time retinal users: Pairing with a calming Soothing Cream helps minimize irritation and supports the adjustment period

Ingredient compatibility and storage guidelines

Avoid using on the same day as products containing high-concentration vitamin C, scrubs, or AHA/BHA. If needed, alternate these products every other night. If you experience stinging or redness, reduce the amount and frequency of application and incorporate calming care. Store the product in a cool place between 3–10°C. If irritation persists, discontinue use and consult a dermatologist.
