Suitable for Skin Type:

• Ideal for normal, dry, combination, and mature skin

• Suitable for textured or aging skin with fine lines or hyperpigmentation

• Use with caution on sensitive or acne-prone skin – start slow and patch test

What Will It Achieve?

• Stimulates collagen production and cell turnover

• Smooths fine lines and wrinkles

• Improves skin texture and tone clarity

• Fades dark spots and post-acne hyperpigmentation

• Provides moisture barrier support via nourishing oils

Key Ingredients:

• 0.5% Retinol (Vitamin A): Potent anti-aging and skin-renewing agent

• Squalane: Lightweight oil that hydrates and prevents irritation

• Tocotrienol (Super Vitamin E): Strong antioxidant, protects skin from oxidative stress

• Sunflower Seed Oil: Emollient base rich in fatty acids to soften skin

• Jojoba Oil: Mimics skin’s natural oils, enhances absorption

• Bisabolol: Calming compound that reduces retinol-induced irritation

Best Used Morning or Evening Routine?

• Strictly PM use only

• Retinol is photosensitive, meaning it breaks down in sunlight

• Must apply SPF 50+ daily when using retinol

Complimented By:

• Hydrating serums (e.g., hyaluronic acid, panthenol)

• Barrier creams rich in ceramides or peptides

• Niacinamide (in a separate routine or layered carefully) to support barrier and brightening

• Layer over or mix with a moisturizer for retinol beginners

Avoid Layering With:

• AHA, BHA, PHA exfoliants

• Vitamin C (L-ascorbic acid)

• Benzoyl peroxide

• Other retinoids or strong actives – risk of irritation
  (These can be used on alternate nights instead)

Which Step in the Routine Does It Belong?
Treatment step – after toner and before (or with) moisturizer

Caution (Things to Be Aware Of):

• Start 2x/week, then increase frequency slowly

• May cause purging in early weeks

• Not recommended for pregnant or breastfeeding individuals

• Always follow with SPF 50+ the next morning

• Keep refrigerated or store in a dark, cool place – retinol is light- and heat-sensitive
