* Milia: Small, white, pearl-like bumps that are trapped keratin under the skin.
* Allergic Reaction/Irritation: Red, itchy, raised bumps due to contact with an irritant.

General Tips for Treating Bumpy Skin:
* Patch Test: Always patch test new products on a small area of skin before applying them to a larger area.
* Start Slowly: Introduce new active ingredients (like retinoids or AHAs/BHAs) gradually to avoid irritation. Use them a few times a week to start, and then increase frequency as tolerated.
* Be Consistent: It takes time to see results. Stick to your routine for at least several weeks before expecting significant improvement.
* Don't Over-Exfoliate: This can damage the skin barrier and make the problem worse.
* Hydrate: Drink plenty of water to keep your skin hydrated from the inside out.
* Sun Protection: Sun exposure can worsen many skin conditions and make exfoliation more irritating. Use a broad-spectrum sunscreen with SPF 30 or higher daily.
* See a Dermatologist: If you're unsure about the cause of your bumpy skin or if over-the-counter treatments aren't working, consult a dermatologist for diagnosis and treatment options. They can provide personalized recommendations and prescription-strength medications if needed.
* Consider Your Environment: Dry climates may exacerbate KP.
Example Routine (for KP):
1. In the Shower: Use CeraVe SA Cleanser on affected areas.
2. After Shower: Apply AmLactin Daily Moisturizing Lotion.
3. Throughout the Day: Apply CeraVe Moisturizing Cream as needed.
4. Sun Protection: Apply SPF to any exposed skin in the morning.
Example Routine (for Comedonal Acne):
1. Morning: Gentle cleanser (like Cetaphil or Vanicream), followed by a lightweight, oil-free moisturizer and sunscreen.
2. Evening: CeraVe Acne Foaming Cream Cleanser (Benzoyl Peroxide). Follow with a serum like The Ordinary Niacinamide 10% + Zinc 1%. Apply a light moisturizer. *On alternate nights (or less frequently at first), use Differin Adapalene Gel instead of the Niacinamide.*
Remember to listen to your skin and adjust your routine as needed. Good luck!
