As a skin therapist I swear by powerful ingredients like retinol and strong acids for their transformative effects, but these products may not be the best choice during the summer months. Particularly for new users, these acids can cause issues in the warmer weather. 1.

Increased skin sensitivity Retinol and acids such as glycolic acid and salicylic acid can make your skin more sensitive to sunlight. These ingredients work by accelerating cell turnover, which can leave fresh, delicate skin more susceptible to sun damage. Exposing skin treated with these ingredients to UV rays can lead to sunburn, hyperpigmentation, and premature ageing.

2. Risk of Sunburn and Irritation During summer, UV radiation is at its peak, and the risk of sunburn is higher. When combined with retinol or strong acids, the likelihood of sunburn and skin irritation further increases.

This can result in redness, peeling, and discomfort, making your skin more vulnerable to damage and undermining the benefits of your skincare routine. 3. Potential for Post-Inflammatory Hyperpigmentation (PIH) Using retinol or strong acids in the summer can also increase the risk of post-inflammatory hyperpigmentation (PIH).

PIH occurs when skin inflammation triggers an overproduction of melanin, leading to dark spots and uneven skin tone. Sun exposure exacerbates this condition, making it more challenging to fade dark spots and achieve a clear complexion. 4.

Compromised Barrier Function Strong acids and retinol can compromise.
