Is La Roche-Posay a good brand?

Yes — it’s a dermatologist-recommended brand in the UK. La Roche-Posay is known for developing high-quality, gentle formulas that work well for sensitive and problem-prone skin types.

Is La Roche-Posay suitable for sensitive skin?

Absolutely. Most La Roche-Posay products are tested on sensitive skin and formulated to be hypoallergenic, fragrance-free, and gentle — making them ideal for easily irritated skin.

La Roche-Posay offers both mineral (physical) and chemical sunscreens, so you can choose the option that works best for your skin type. Mineral options are ideal for sensitive or allergy-prone skin.

How do I use La Roche-Posay Cicaplast Baume B5?

Apply once or twice daily to clean, dry skin. Use it on the face, body, lips or hands — anywhere that’s dry, irritated or in need of soothing care. It’s also suitable for nappy rash or after minor skin procedures.

What is the thermal spring water in La Roche-Posay products?

This is the brand’s signature ingredient, rich in selenium and antioxidants. Sourced from the French town of La Roche-Posay, the thermal spring water helps soothe inflammation and calm sensitive skin.

Is La Roche-Posay sunscreen good?

Who owns La Roche-Posay?

La Roche-Posay is owned by the L'Oréal Group, under its Dermatological Beauty division, alongside other reputable skincare brands like CeraVe and Vichy.

Is La Roche-Posay good for acne?

It is. The Effaclar range, in particular, is formulated to target blemishes, oily skin and acne-prone conditions using proven ingredients like salicylic acid, niacinamide, and zinc PCA.

Can I use La Roche-Posay products while on acne medication?

Yes, many of their products are suitable alongside prescription treatments. Opt for non-exfoliating cleansers and moisturisers that support skin barrier repair. Always check with your dermatologist if unsure.

How long does La Roche-Posay sunscreen last?

You should reapply it every two hours, especially after swimming, sweating or towel drying. This helps ensure ongoing protection against harmful UV rays.

How do I use La Roche-Posay Effaclar Duo?

Apply in the morning after cleansing. Warm a pea-sized amount between your fingers and smooth it over the face, avoiding the eye area. It helps target breakouts and reduce blemish marks.

Is La Roche-Posay non-comedogenic?

Most of the brand’s products, especially those for acne or sensitive skin, are non-comedogenic, meaning they won’t clog your pores. Always check individual product labels to be sure.

Is La Roche-Posay Effaclar safe for pregnancy?

Some Effaclar products are safe for pregnancy, while others (like those with salicylic acid) should be used with caution. Speak to your GP or midwife before adding new products to your routine.

What does La Roche-Posay Cicaplast do?

Cicaplast Baume B5 is a rich, fragrance-free balm that helps soothe and repair cracked, irritated, or dry skin. It forms a protective barrier and hydrates skin exposed to harsh conditions or irritation.

Does La Roche-Posay Effaclar Duo contain retinol?

No, it doesn’t. Instead, it uses salicylic acid, niacinamide, and LHA to exfoliate the skin and treat blemishes without the irritation sometimes associated with retinol.

How do I use La Roche-Posay Effaclar?

Here’s a typical routine:

Cleanse: Use the Effaclar Foaming Gel.
Tone: Apply toner with a cotton pad.
Moisturise: Apply Effaclar Duo or your preferred moisturiser. You can follow with make-up if desired.

Use once daily, preferably at night. Dispense a few drops onto your fingertips and gently press into the skin, avoiding the eye area. Always follow with SPF in the morning while using this serum.

What age group is La Roche-Posay suitable for?

Everyone! From babies to teenagers and adults, there are products to suit every age. Look out for the Lipikar and Cicaplast ranges for little ones, and Effaclar for teens or adults managing acne.

Which La Roche-Posay product is best for rosacea?

The Rosaliac range is designed for redness-prone skin and helps to calm inflammation while strengthening the skin’s barrier. It’s gentle and free from common irritants.

Do La Roche-Posay products contain fragrance?

Many of their products are fragrance-free, especially those designed for sensitive or reactive skin. Always check the product label if fragrance is a concern for you.

Which La Roche-Posay product is best for hyperpigmentation?

Try the Pure Vitamin C10 Serum or Mela-D Pigment Control. These products are formulated to help fade dark spots and even out skin tone for a more radiant complexion.

Are La Roche-Posay products vegan?

Some products may contain animal-derived ingredients, so not the entire range is vegan. If vegan skincare is essential for you, check the product ingredient lists or consult us directly.
