AHA Skincare Reactions: Sun Exposure and Sensitivity Issues - Dermatology

More Info

---

When using AHA (alpha hydroxy acids) skincare products, such as glycolic acid or lactic acid, it is essential to understand how these ingredients interact with your skin, especially when exposed to sunlight. AHA products are known for their exfoliating properties, which can help improve skin texture and tone. However, they also increase skin sensitivity, particularly to UV radiation. This heightened sensitivity can lead to reactions such as redness, peeling, and itching, especially if you have recently increased your sun exposure.

In your case, it seems that after a month of using your AHA product without issues, you have started experiencing redness and peeling after spending more time in the sun. This could be attributed to a few factors:
1. Increased Sun Sensitivity: AHA products can make your skin more susceptible to sun damage. When you exfoliate the skin, you are removing the outermost layer of dead skin cells, which can leave the newer, more sensitive skin underneath exposed. This can lead to a higher likelihood of sunburn or irritation when exposed to UV rays.

2. Inadequate Sun Protection: If you are not using a broad-spectrum sunscreen with adequate SPF while using AHA products, your skin may not be sufficiently protected from the sun. It is crucial to apply sunscreen daily, even on cloudy days, and to reapply it every two hours when outdoors, especially if you are sweating or swimming.

3. Potential Allergic Reaction: While it is less common, some individuals may develop an allergic reaction to AHA products, leading to symptoms such as redness, itching, and peeling. If you suspect that your skin is reacting negatively to the product, it may be worth discontinuing use and consulting a dermatologist for further evaluation.

4. Skin Barrier Compromise: Overuse of exfoliating products can compromise the skin barrier, leading to increased sensitivity and irritation. If you have been using the AHA product more frequently than recommended, it may be beneficial to reduce the frequency of application and incorporate a gentle moisturizer to help restore the skin barrier.

To address your concerns, consider the following steps:
- Discontinue Use Temporarily: If you are experiencing significant irritation, it may be wise to stop using the AHA product for a while to allow your skin to recover.

- Use Sunscreen: Ensure you are applying a broad-spectrum sunscreen with at least SPF 30 every day. Look for sunscreens that are formulated for sensitive skin and are non-comedogenic.

- Moisturize: Incorporate a good moisturizer into your routine to help soothe and hydrate your skin. Look for products that contain ingredients like hyaluronic acid, ceramides, or glycerin, which can help restore the skin barrier.

- Consult a Dermatologist: If your symptoms persist or worsen, it is essential to seek professional advice. A dermatologist can provide personalized recommendations based on your skin type and concerns.

In summary, while AHA products can be beneficial for your skin, they require careful use, especially in relation to sun exposure. By taking the necessary precautions and listening to your skin's needs, you can minimize adverse reactions and maintain healthy skin.
