Product Summary
"Medik8 - Crystal Retinal 3 GWP" is effective for: Anti-aging, Evens skin tone and Anti-blemish
This product could be helpful for: Moisturizing, but its actives are not the most effective or are not well-studied.
Ingredient callouts
- this product contains an effective form of Retinoids (vitamin A): retinal 0.50% - 0.75%. Retinoids are potent multitasking actives. They work to improve and prevent early signs of aging, reduce hyperpigmentation (age spots and post-acne marks), and prevent inflamed blemishes and clogged pores. The downside of Retinoids is that they can be irritating. If you are not already using a Retinoid in your routine, it is best to start slowly and apply the Retinoid product only a few times per week. If your skin tolerates it well, you can gradually increase the frequency to daily.
- Humectants (glycerin 4.20% - 5.20% and sodium hyaluronate 0.55% - 0.85%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

Anti-aging
What does the product description say?
With a lightweight, silk-like texture that absorbs quickly into the skin, this powerful serum renews and resurfaces the skin, visibly minimises fine lines and wrinkles, reduces blemishes and pigmentation and delivers a healthier, brighter and more even-toned complexion.

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains retinal.
Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.
One step removed from the biologically active in skin form of vitamin A. Once converted to the retinoic acid in the skin, retinal is proven to be effective against all signs of aging. It improves skin cell turnover, helps fight blemishes and clogged pores, can regulate excess oil production and even skin tone. Concentrations of 0.05% and 0.1% are shown to be effective. It can, however, be irritating
Being a lipid soluble form of vitamin C, it is more stable than ascorbic acid, but still degrades quickly and needs to be stabilized in a formulation with another ingredient. It is claimed to penetrate skin better than pure vitamin C and have the the similar benefits, but solid studies of its effectiveness are lacking. Is likely to require a higher concentration in a product than pure vitamin C to be effective. It might be able to help reduce pore clogging.
A vitamin C derivative that is more stable but less potent than pure form of vitamin C. Can help neutralize free radicals and help reduce hyperpigmentation, but the required concentration is likely to be much higher than for the pure form of vitamin C, limiting the ingredient's effectiveness in products

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: retinal.
Keep in mind that you would need to apply any topical skincare targetted at hypigmentation consistently for a couple of months to get a result. No topical skincare product can help get rid of hyperpigmentation (including post-acne marks and age spots) instantly.

Moisturizing
What does the product description say?
With other key ingredients including Hyaluronic Acid and Vitamin E, the skin is hydrated at every level, leading to a plumper and smoother complexion and the skin barrier is strengthened, helping to lock in moisture.
Source: Face the future
This product can help improve hydration of the skin with the two types of ingredients.
The first type is called “humectants”:
these ingredients help attract water.
When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from
within deeper layers of the skin. The following ingredients in this product do the job:
glycerin, sodium hyaluronate.
This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: caprylic/capric triglyceride, squalane.
An oil naturally present in skin. Works as an emollient to soften the skin and form a protective layer on its surface without a greasy feeling.
A good mix of fatty acids that forms a protective layer on the skin. Improves the shelf life of products. Derived from coconut and glycerin
