A large-format retinal serum formulated with 0.01% retinal, niacinamide, hyaluronic acid, ceramide, centella, and soothing botanical ingredients to support hydration and improve the appearance of dullness, uneven tone, and rough texture.

Our verdict

MEDITHERAPY Retinal Skin Booster Serum is a 5.07 fl. oz face-and-body serum designed for users who want to introduce a low-strength retinal product into their skincare routine. Amazon reviewers frequently praise its silky, non-greasy texture and ability to leave skin feeling hydrated, soft, and smoother. Many users also appreciate the unusually large bottle and report that it layers comfortably under moisturizer. However, the product contains 100 ppm retinal, equivalent to approximately 0.01%, so it is a relatively mild retinal formula. It may suit beginners, but users expecting dramatic or rapid changes in wrinkles, dark spots, or uneven texture may find the results subtle. The brand's official ingredient list confirms retinal alongside niacinamide, sodium hyaluronate, ceramide NP, panthenol, centella-derived ingredients, and several antioxidants.

What stands out

  • Beginner-Level Retinal — Contains approximately 0.01% retinal for gradual vitamin A care
  • Large 5.07 fl. oz Size — Provides significantly more product than most facial retinal serums
  • Face and Body Use — Can be applied to the face, neck, chest, arms, or other areas with uneven-looking texture
  • Niacinamide — Supports a brighter, more even-looking complexion
  • Barrier-Supporting Ingredients — Ceramide NP, cholesterol, panthenol, and beta-glucan help maintain moisture
  • Soothing Botanical Blend — Includes centella, oat, green tea, and madecassoside to complement the retinal formula

How to use

Apply a small amount to clean, dry skin after toner and before moisturizer. For beginners, use it two or three evenings per week and gradually increase the frequency according to skin tolerance. When applying it to the body, spread a thin layer over areas of uneven texture and follow with moisturizer if needed. Use broad-spectrum sunscreen every morning. Avoid combining it in the same routine with strong exfoliating acids, benzoyl peroxide, or another retinoid until your skin's tolerance is established. Mild dryness or temporary irritation can occur with retinal products. Stop use if persistent burning, peeling, or redness develops. Retinoids are generally avoided during pregnancy unless a healthcare professional advises otherwise.

Frequently asked questions

Is the MEDITHERAPY Retinal Serum good for beginners?

Yes — at roughly 0.01% retinal it is a mild formula suited to first-time retinoid users. Start two or three evenings per week and increase gradually as your skin tolerates it.

Can I use it on my body?

Yes — the large 5.07 fl. oz bottle is marketed for face and body. Apply a thin layer to areas of uneven texture like the chest, arms or neck, and follow with moisturizer if needed.

Can I use it with other retinoids or acids?

Avoid combining it with another retinoid, strong exfoliating acids or benzoyl peroxide in the same routine, as that raises irritation risk. Introduce one retinoid at a time and wear sunscreen every morning.

Is 0.01% retinal strong enough to do anything?

It is a gentle strength, so changes in texture and tone are subtle and build slowly over weeks or months. Users expecting rapid wrinkle reduction will likely find it too mild, but it suits beginners building tolerance.
