Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers excellent visible anti-aging effects for you due to retinaldehyde and hyaluronic acid, which minimize fine lines and wrinkles and plump the skin, though these ingredients offer limited direct benefits for your dry or flaky skin and sensitivity.
- Glycerin and squalane provide hydration and emollient action, which are beneficial for your dry skin type, but do not fully address your primary concerns.
- The product is safe for your dry and sensitive skin as it contains no harsh or prohibited ingredients.
How to apply
- Use this PM routine for your evening skincare. Start using the serum 3 times a week and increase to daily use if your skin feels comfortable.
- Apply the serum after cleansing and toner, but right before your moisturizer. This step locks in deep hydration for dry skin.
- Gently press 2-3 drops of the serum into your skin using your palms. Let it absorb completely for a minute ⏱ before applying your next product.
- Since your skin is sensitive, apply the serum on completely dry skin for better tolerance and less irritation.
- Avoid the sensitive eye area during application. Always do a patch test before your first use to ensure your skin reacts well.
People Say

It is frequently described as a "game changer" for smoothing fine lines and clearing congestion, though the high price point is a common contention.

Questions and answers
How well does Medik8 Crystal Retinal 3 work for dry sensitive skin?
Medik8 CRYSTAL RETINAL 3 works moderately well for dry sensitive skin, offering great anti-aging benefits while adding some moisture with glycerin and squalane, though it does not fully target dryness and sensitivity. Treatments that fit dry sensitive skin better need ingredients that provide deep hydration and skin barrier support without any risk of irritation.
Which ingredients make this serum a good fit for dry sensitive skin?
Glycerin and squalane help make this serum a fit for dry sensitive skin by providing hydration and soothing moisture. For this skin type, a product needs effective moisturizing ingredients and ceramides that provide excellent hydration and texture improvement without irritation.
What does Retinal do for dry sensitive skin?
Retinal may help smooth fine lines and improve skin texture, but for dry and sensitive skin it is unlikely to be a good fit on its own. This skin type needs products that include gentle hydrating ingredients like hyaluronic acid and glycerin to lock in moisture and protect the skin barrier.
What does Hyaluronic Acid do for dry sensitive skin?
Hyaluronic acid is a great fit for dry, sensitive skin because it brings a large boost in hydration, making the skin feel soft and smooth while improving barrier function. It helps calm tightness and dryness, and is unlikely to cause irritation.
Journal of Drugs in Dermatology, 2011Dermatology and Therapy, 2021
Where does this serum go in a skincare routine for dry sensitive skin?
This treatment goes in the evening routine after your toner and before your moisturizer. A product of this type for dry sensitive skin needs rich nourishing ingredients like ceramides, shea butter, or plant oils to deeply soothe flakiness and comfort tightness.
Can I use it with niacinamide, and in what order?
You can use this treatment with niacinamide by applying niacinamide first to calm and hydrate your skin before adding the retinaldehyde product. This helps minimize potential dryness or irritation.
How often should I use this serum?
Use this treatment in your evening routine, starting just once a week to help your dry sensitive skin adjust safely. This type of skin needs a gentle formula packed with hydrating ingredients and soothing agents to prevent dryness and irritation while you build up tolerance.
Facial Plastic Surgery, 2014Clinical, Cosmetic and Investigational Dermatology, 2017
Can it clog pores, cause breakouts or purging for dry sensitive skin?
Medik8 CRYSTAL RETINAL 3 is unlikely to clog pores or cause breakouts on dry sensitive skin, but the retinaldehyde in it may cause initial purging or mild dryness. This product provides safe anti-aging care, though dry and sensitive skin needs formulas packed with extra nourishing oils and soothing ingredients to fully lock in moisture and calm irritation.
Is this serum fragrance-free and alcohol-free?
Yes, it has no fragrance and no drying alcohol. Cetearyl alcohol is a fatty alcohol, which soften the skin.
