anua Collagen Retinol Refining Guasha Neck Cream

Features

The anua Collagen Retinol Refining Guasha Neck Cream combines a specialized guasha tool and a firming cream into an all-in-one home-care device. Designed with an ergonomic deep curve head, the wide W-shaped guasha applicator contours seamlessly to the face, neck, jawline, trap muscles, and scalp for precise, targeted massage care. It features a smart on and off cap mechanism that allows you to easily twist the nozzle to dispense the cream hygienically.

Benefits

This cream delivers intensive elasticity and adherence care from the neck down to the facial contours to help refine sagging lines. The combination of retinol-formulated capsules and a resilient high-elasticity cream works directly on targeted areas to deeply deliver active ingredients into the skin's stratum corneum as the guasha head glides across the skin.

Main Ingredients and their effects

Retinol: Formulated at 0.03 percent to help target wrinkle care and skin texture refinement. Hydrolyzed Collagen: Included to support skin conditioning and elasticity synergy alongside the retinol capsules. Niacinamide: Works to brighten and support overall skin clarity.

Clinical test results

Based on a human application test conducted by the Korea Institute of Dermatological Sciences on 31 adult females over the age of 30 from February 11, 2026, to February 25, 2026, participants noted visible improvements in jawline elasticity by 2.48 percent and neck region elasticity by 2.53 percent after 2 weeks of use. Additionally, 100 percent of participants agreed that their neck and jawlines appeared more refined and that the product could be used mildly and daily without irritation. The product has also completed primary skin irritation testing, sensitive skin suitability testing, and cumulative skin irritation testing for hypoallergenic assurance.

Usage instructions

Prepare your target areas with a toner or mist, or use at the final step of your usual evening skincare routine for the face. Turn the guasha head marker to the ON position and squeeze out an appropriate amount of cream. Apply generously to the desired areas and use the guasha head to massage from bottom to top for about 5 minutes. After use, turn the head marker to OFF and clean the applicator with a wet tissue.

Because this product contains pure retinol, a skin adaptation period is recommended. For the first 14 days, use every other day, and transition to daily evening use only after 2 weeks. If you experience irritation, reduce usage frequency or mix with a soothing serum or moisturizer, and always apply sunscreen if using during the morning.
