Skincare & Cancer: How to Care for Your Skin During Treatment?

by CS

Cancer treatments like chemotherapy and radiotherapy can have a significant impact on the skin, causing discomfort and visible changes. While these side effects are rarely life-threatening, they can deeply affect quality of life. That’s why adopting a gentle and safe skincare routine is essential.

SERENI BIO : Organic Skincare Created for Sensitive, Treated Skin

Serenibio is the first French certified organic and vegan-friendly dermo-cosmetic line, specially developed for men and women undergoing cancer treatments. Formulated in collaboration with patients and socio-estheticians, these products are manufactured in France by Laboratoires E.V. ROIG—trusted experts in organic beauty care since 1972. 

Common Skin Side Effects from Cancer Treatments

1. Hair Loss
Hair thinning or loss typically starts 2–3 weeks after beginning chemotherapy. It may also affect eyelashes and eyebrows, and in some cases, alter hair texture.

2. Brittle Nails & Dry Skin
Nails may become soft, split, or break more easily. The skin, due to reduced cellular renewal, often becomes dry, irritated, and more vulnerable to redness, inflammation, and micro-lesions.

3. Hyperpigmentation
Brown or purplish spots may appear, especially around injection sites, and sometimes spread to nails and other body areas. Sun protection is essential to prevent worsening.

4. Rashes & Redness
Small pimples, itchiness, and localized inflammation often occur shortly after starting treatment. Soothing mists and anti-redness serums, such as those from Sérénibio, can help calm the skin.

Fortunately, most of these symptoms are temporary and improve once treatment ends.

Why Choose Organic Skincare During Cancer?

1. Avoid Endocrine Disruptors
Up to 40% of conventional beauty products contain harmful substances like parabens, silicones, BHA, and phenoxyethanol—linked to hormone disruption, fertility issues, and even increased cancer risk. Organic skincare avoids these risks entirely.

2. Reduce Irritation on Already Fragile Skin
Conventional formulas often contain sulfates and synthetic fragrances, which are harsh and drying. Organic products like the Serenibio Soothing CICA Shampoo cleanse gently without irritating sensitive skin or scalp.

3. Support Skin Regeneration Naturally
Serenibio’s range is rich in botanical extracts and vegetal oils that nourish and repair the skin. Free from harsh chemicals, it helps maintain hydration and promotes cellular renewal, even during active treatment.

4. Reconnect with Your Femininity and Self-Care
Caring for your skin is more than cosmetic—it’s therapeutic. Maintaining a gentle beauty ritual helps reduce stress, rebuild self-confidence, and restore a sense of normalcy.

5. Understand What’s in Your Products
With minimal regulation in some markets, it's important to choose certified organic products (COSMOS, Cosmébio) and avoid being misled by “greenwashed” labels.

6. Say No to Greenwashing
Certified organic products must meet strict ingredient and ethical standards, unlike conventional brands that often use misleading marketing to appear “natural.”

SERENI BIO: A Complete Skincare Routine for Sensitive Skin

The Serenibio line is entirely free of essential oils and chemical irritants. Used by professional socio-estheticians, this collection includes everything needed for a soothing skincare routine—cleanser, toner, serums, creams, and oils—designed specifically for weakened, reactive, or post-treatment skin.

The Role of Socio-Estheticians in Cancer Care

Trained in both aesthetics and oncology, socio-estheticians provide personalized skincare and emotional support. Here’s why their expertise matters:

  • Tailored Care: They understand how cancer treatments affect skin, nails, and hair and adapt beauty routines accordingly.

  • Improved Well-Being: Targeted care helps restore comfort, confidence, and quality of life during and after treatment.

  • Emotional Support: Socio-estheticians offer a calming, safe space for patients navigating physical and emotional changes.

  • Practical Guidance: From product recommendations to makeup tips, they empower patients with the knowledge to care for themselves at home.

  • Restoring Femininity: Whether through massage, skincare, or gentle makeup, they help individuals reconnect with their identity and self-image.

Are Cosmetics Linked to Cancer?

While cosmetics are not a direct cause, certain ingredients in conventional products pose risks:

  • Endocrine Disruptors (e.g., parabens, phenoxyethanol)

  • Irritants (e.g., sulfates, synthetic fragrances, mineral oils)

  • Long-term Exposure Risks: hormonal disruption, fertility concerns, and even cancer.

To reduce risks:

  • Choose certified organic, vegan, and fragrance-free products.

  • Avoid greenwashing and read ingredient labels carefully.

  • Opt for formulations without essential oils if your skin is ultra-sensitive.

Makeup Tips During Cancer Treatment

What to look for:

  • Certified organic and vegan formulas

  • Hypoallergenic, fragrance-free, and chemical-free ingredients

  • Specialized lines for sensitive or post-treatment skin

What to avoid:

  • Parabens, sulfates, silicones, phenoxyethanol, and synthetic dyes/fragrances.

Bonus tip: Consult a socio-esthetician for personalized advice and product application techniques to help maintain a radiant, confident appearance.

Final Thoughts

Serenibio was born out of a commitment to protect and care for the most delicate skin. Certified organic, vegan, and dermatologically tested, these products are more than cosmetics—they are tools of well-being, healing, and empowerment.

Whether you're undergoing treatment or supporting a loved one, Serenibio offers a gentle path to reconnect with yourself, naturally and safely.
