The Skincare Upgrade Your Routine Needs

Educational Blog:

Ready to reset your skincare routine the right way? Here's exactly how to apply Tretinoin using the sandwich method:

Step 1: Cleanse

Wash your face with a gentle, non-stripping cleanser. Avoid anything with exfoliating acids or active ingredients on nights you're using Acretin.

Step 2: Pat Dry — But Not Completely

Leave your skin slightly damp. Damp skin absorbs moisturizer better, which sets up the perfect base layer for your sandwich.

Step 3: Apply Your First Moisturizer Layer (The Bottom Bread)

Apply a thin, even layer of a gentle, fragrance-free moisturizer all over your face. Wait 1–2 minutes to let it partially absorb before moving to the next step.

Best ingredients to look for: hyaluronic acid, ceramides, glycerin, squalane.

Step 4: Apply Tretinoin (The Filling)

Apply a pea-sized amount of Tretinoin evenly across your face, avoiding the immediate eye area and corners of the mouth. A little goes a long way — more product does not mean faster results.

Step 5: Seal with Your Second Moisturizer Layer (The Top Bread)

Immediately apply another layer of moisturizer on top of the tretinoin to seal everything in and create that protective sandwich barrier.

Step 6: Wake Up and Apply SPF (Non-Negotiable)

Tretinoin increases your skin's photosensitivity. Every single morning, apply a broad-spectrum SPF 30 or higher. This protects your results and prevents further damage.
