Celimax’s The Vita-A Retinal Shot Tightening Booster is a targeted wrinkle-smoothing treatment that is powered by retinal (with an a)–a more potent vitamin A derivative than retinol. Though the latter is generally known as the gold standard in skincare, retinal actually converts more efficiently into retinoic acid within the skin—delivering faster, more visible anti-aging results, helping to soften fine lines, refine texture, and improve overall skin clarity.
It’s no surprise, then, that the before-and-afters have gone viral on TikTok as creators apply overnight, and in just a few days, demonstrate the Booster’s filling effect. The shareable nature of the application is also down to its distinctive technique. Instead of uniformly spreading across the face, it can be harnessed as a precise and targeted treatment, spread directly on areas of concern.
With almost miraculous effects, just a drop of this Korean cream is enough to boost elasticity in the skin, even on neck wrinkles. The treatment contains 0.1 percent pure retinal and 3 percent Matrixyl 3000, a combination that improves skin resilience and texture. Penetrating deeply, it also promotes a more toned and even appearance, while minimizing wrinkles.
You will also find A-Shot in the ingredient lineup, a complex made up of tiny particles for better absorption and to stimulate cell turnover. For targeted action on fine lines, the formula also contains 1 percent panthenol, or vitamin B5, which gives it a soothing and moisturizing effect that amplifies the effects of the retinal.
The Benefits of Celimax’s Retinal Booster
There’s little not to love about Celimax’s retinal booster. “This serum uses liposomized retinal, which helps stabilize the ingredient and improve penetration into the skin,” Dr. Collins previously explained. “The addition of peptides such as Matrixyl makes it particularly appealing for patients focused on improving skin firmness and elasticity while still targeting fine lines and texture.” A bit more of its benefits broken down below.
- Reduces fine lines and wrinkles by accelerating cell renewal
- Has a lifting effect
- Lightly exfoliates the skin to improve the absorption of actives
- Stimulates collagen production
- Intensely moisturizes
- Soothes and strengthens the skin barrier by harnessing the power of allantoin
Who should use Celimax The Vita-A Retinal Shot Tightening Booster?
Celimax’s retinal cream is ideal to call upon at the first appearance of wrinkles; though Vogue’s Kiana Murden is currently using it as a preventative treatment. The inclusion of the most active form of retinal means it acts on cell turnover and collagen production to tackle premature signs of aging. It works to smooth skin’s texture and firm, counteracting loss of tone and evening out skin’s texture. Be cautious, however, if you have really very sensitive skin because retinal is a very potent ingredient, which means the booster is not suitable for all skin types and may cause redness or irritation. That said, Murden is sure to use it on nights when skin feels hydrated—sandwiching the retinal in between a nourishing toner and occlusive face cream for good measure.
How to Use Celimax The Vita-A Retinal Shot Tightening Booster
Equipped with a handy thin applicator, which facilitates a targeted approach to wrinkles, the Celimax The Vita-A Retinal Shot Tightening Booster should be used in the evening—massaged on gently to promote absorption. To maximize its benefits and not risk irritation, start by using the product only twice a week, gradually increasing the frequency by combining it with a moisturising and soothing cream. Then, in the morning, finish the routine by applying sunscreen.
