The combination of avocado and Vaseline (petroleum jelly) taps into two distinct, powerful pillars of skincare: intense nourishment and ultimate moisture retention. While no topical treatment can literally reverse your age, this duo is highly effective at minimizing the visible signs of aging by addressing the root cause: dryness and barrier breakdown.

The idea is that Avocado provides the vitamins and emollients, and Vaseline acts as the seal, trapping that goodness and moisture deep within the skin, leading to a visibly plump, dewy, and younger-looking complexion.
1. Avocado: The Deep Nourisher and Builder
Avocados are rich in essential components that the skin loves:1
- Healthy Fats (Oleic Acid): These monounsaturated fats are easily absorbed by the skin’s outer layer (the epidermis).2 They strengthen the natural lipid barrier, which is essential for protecting against environmental damage and water loss.3
- Vitamins E and C: These are powerful antioxidants that fight the free radicals responsible for breaking down collagen.4 Vitamin C is also crucial for collagen production, helping the skin retain its firmness and elasticity.5
- Carotenoids (Lutein): These antioxidants are known to help protect the skin from UV-induced damage and inflammation, which are major contributors to wrinkles and age spots.6
2. Vaseline (Petroleum Jelly): The Ultimate Occlusive Seal

Vaseline does not moisturize on its own, but it is one of the most effective occlusive agents available, which is why it is used in the popular “slugging” skincare trend.
- Locks in Hydration: It creates a semi-occlusive barrier on the skin’s surface, preventing up to 98% of Transepidermal Water Loss (TEWL). This prevents dryness and keeps the skin hydrated and plump overnight.
- Amplifies Ingredients: When applied over a nourishing layer like avocado, Vaseline prevents those beneficial compounds, fats, and moisture from evaporating, allowing your skin ample time to absorb them.
- Reduces Fine Lines: By sealing in maximum moisture, the skin swells slightly, which temporarily minimizes the appearance of fine lines and gives a smooth, “glass-skin” or dewy finish often associated with youth.7
DIY Recipe: Hydrating Overnight Mask (Slugging Method)
This mask is best used as an intensive overnight treatment one to two times per week.
Ingredients
- 1 tablespoon Mashed Ripe Avocado (make sure it is lump-free)
- 1 teaspoon Honey (Natural humectant to draw moisture in)8
- A pea-sized amount of Vaseline (Petroleum Jelly)
How to Use

- Cleanse Thoroughly: Wash your face with a gentle cleanser to ensure your skin is clean and slightly damp.9
- Apply Avocado Layer: Mix the mashed avocado and honey to form a smooth paste.10 Apply this generously over your face, avoiding the immediate eye area. Leave it on for 10–15 minutes to allow the vitamins to penetrate.11
- Rinse: Gently rinse the avocado mixture off with lukewarm water and pat your skin dry.12
- The Slugging Step (Vaseline): Take a very small, pea-sized amount of Vaseline (or a similar occlusive ointment) and gently warm it between your fingertips. Pat or lightly smooth a very thin layer over the areas you want to protect (like the cheeks, forehead, and neck).
- Sleep: Leave the thin occlusive layer on overnight. In the morning, your skin should feel incredibly soft, plump, and dewy.
Note: The Vaseline step is generally best for those with dry, sensitive, or mature skin. If you have oily or acne-prone skin, use the Vaseline step sparingly, as the heavy occlusive nature may trigger breakouts for some individuals.
