Difference with General Recipe:

1. Emollient: Shea butter and avocado oil are chosen for their rich, nourishing properties, beneficial for dry skin, while also providing anti-aging benefits.

2. Active Ingredients: Retinol is an excellent anti-aging active, while peptides and ceramides help restore skin barrier, providing hydration and reducing the appearance of wrinkles. Hyaluronic acid is a great active ingredient for both dry and aging skin due to its capacity to hold up to 1000 times its weight in water and its role in skin cell renewal and collagen production.

3. Humectant: Hyaluronic acid or sodium PCA are ideal for dry skin due to their high moisture retention properties.

Remember, sun protection is crucial when using active ingredients like retinol as they can increase your skin's sensitivity to the sun.
