An $18 Korean Retinol Serum Promises Anti-Aging Results: A Review

A Korean skincare serum priced at $18 and boasting over 100,000 monthly purchases on Amazon has garnered attention for its anti-aging potential. The celimax Retinal Shot, formulated with retinal, a derivative of vitamin A, aims to provide visible results without overwhelming the skin.

Victoria McDonnell, a commerce journalist for the New York Post, tried the serum as part of her introduction to retinol products. She noted that retinal is known to be more efficient than traditional retinol and can be suitable for many skin types when introduced gradually. The serum also contains peptides, including Matrixyl, which are intended to support skin firmness and address fine lines and elasticity.

McDonnell began using the celimax Retinal Shot a few times a week at night, applying a small amount and following with a moisturizer. She avoided other strong exfoliating products on those nights to simplify her routine. Her initial impression was that the serum had a lightweight texture that absorbed quickly without a greasy feel. She experienced no tingling, and her skin remained comfortable post-application. By the following morning, the under-eye area appeared hydrated, with no redness or flaking, which she found encouraging as a newcomer to retinal products.

Though the serum has a slightly yellow hue, it blended into the skin with gentle patting. McDonnell described a subtle tightening effect, indicating the product was active. After consistent use, she observed gradual improvements, including smoother skin around the eyes and less noticeable settling of concealer into fine lines. While not experiencing overnight transformations, she noted her skin gradually looked firmer and more refreshed.

McDonnell found the serum to be more effective for firming and brightening than other anti-aging products she had tried, even comparing it favorably to a higher-priced alternative. She also appreciated its ease of integration into her existing evening skincare routine.

She acknowledged that some temporary redness or breakouts can occur when using retinol as it accelerates cell turnover, a phenomenon she experienced to a small degree but which eventually subsided. She noted that pimple patches can help manage these occasional breakouts.

Given its $18 price point and the observed effects, McDonnell concluded that the celimax Retinal Shot is a popular and worthwhile option for those looking to introduce retinal into their skincare regimen, provided they are patient with the results. She emphasized that while no product can eliminate all signs of aging, her experience with the serum was positive enough to continue using it.
