What Happens to Your Skin During Chemo & Radiation
Your Skin Barrier is Weakened
Chemo and radiation can impair the production of lipids, ceramides, and structural proteins that make up your skin's protective layer. When it's compromised, moisture escapes more easily, irritants penetrate more easily, and skin becomes more fragile. This is why even products you’ve used forever may suddenly feel uncomfortable or burn.
Cell Turnover Slows Down
Healthy skin constantly sheds old cells and replaces them with new ones, but Cancer treatments disrupt this cycle.
The result?
- Dullness
- Dryness
- Flaking or scaling
- Rough texture
- Slower recovery from irritation or wounds.
Your skin simply isn’t regenerating at its usual luxury-spa pace. It’s conserving energy for survival.
Inflammation Increases
Both chemo and radiation trigger inflammatory responses in the skin. That inflammation shows up as:
- Redness
- Itching
- Tenderness
- Heat or sensitivity to touch
Radiation adds a second layer of stress by directly damaging skin cells in the treated area, which can cause:
- Peeling
- Blistering
- Weeping or raw patches
- Long-term pigment changes
Oil Production Drops
Oil glands are highly sensitive to treatment. When oil production decreases:
- Skin loses its natural lubrication
- Tightness and cracking become common
- Fine lines suddenly look deeper
- Makeup and sunscreen sit poorly
Dry skin isn’t just uncomfortable — it’s more vulnerable to damage and infection.
Sun Sensitivity Skyrockets
Both chemo and radiation make skin dramatically more photosensitive. That means:
- UV rays penetrate more deeply
- Sunburn happens faster
- Pigment changes occur more easily
- Healing takes longer after sun exposure
Even brief sun exposure that never used to be an issue can suddenly cause redness, pain, or long-lasting discoloration.
