KEY INGREDIENTS

0.03% Encapsulated Retinaldehyde (Retinal)

A next-generation form of vitamin A clinically shown to work up to 11 times faster than retinol. It helps stimulate collagen production, reduce wrinkles, improve skin texture, brighten pigmentation, and promote smoother, healthier-looking skin.

Multi-Weight Hyaluronic Acid

Provides multi-level hydration by attracting and retaining moisture, helping the skin appear plumper, smoother, and more supple.

Vitamin E

A powerful lipid-soluble antioxidant that protects the skin from free radical damage while stabilizing retinal for maximum effectiveness.

Glycerin

A natural humectant that attracts and locks moisture into the skin, improving comfort and preventing dehydration.

HOW IT WORKS

Retinoic acid is the biologically active form of vitamin A responsible for stimulating collagen production and accelerating skin renewal. Traditional retinol must first convert into retinal and then into retinoic acid before becoming active.

Crystal Retinal contains retinaldehyde, requiring only one conversion step to become retinoic acid, making it significantly faster and more effective than retinol. Medik8's patented crystal encapsulation technology protects retinal from degradation while allowing it to be gradually released into the skin throughout the night, maximizing efficacy and minimizing irritation.

Unlike traditional retinol, retinal also possesses direct antibacterial activity against acne-causing bacteria, making it highly effective for both aging and blemish-prone skin.

DIRECTIONS FOR USE

In the evening, after cleansing, apply a small amount evenly to the face, neck, and décolleté. Allow the serum to absorb before applying your moisturizer.

Introduce the product gradually:

• Weeks 1–2: Use twice a week.

• Weeks 3–4: Use every other night.

• After 4 weeks: Use nightly as tolerated.

Always apply a broad-spectrum sunscreen the following morning and continue daily sun protection while using retinal.

Important: If you are pregnant or breastfeeding, consult your healthcare professional before using products containing vitamin A.
