A acid sunscreen
Tomorrow, I should be coming to your clinic.
I'm still dealing with the same issue regarding pigmentation.
I've been using the cream for a month, but I don't see much difference, and it's really frustrating.
Also, could you recommend some sunscreen products suitable for use after taking isotretinoin, including their price range? I apologize for asking the same questions again tomorrow!

Hello: Regarding your question, it is actually a common concern faced by every acne patient.
Addressing patients' doubts and supporting them in their treatment is a fundamental responsibility of physicians, so please do not feel embarrassed.
Once acne has caused indentations or pigmentation, significant effort is required for recovery, with indentations being more challenging than pigmentation.
Currently, there are effective medications available that can help lighten pigmentation more quickly; however, even with these treatments, it still takes time to see results.
As long as you are patient and diligent with sun protection, along with using products or medications that lighten pigmentation, you will gradually notice improvements.
You are already using the best medications; the rest is up to time, which will guide you to the end of your treatment.
Wishing you all the best.

More Info
When it comes to selecting the best sunscreens after using retinoids, it is essential to understand the unique needs of your skin during this period. Retinoids, which are derivatives of vitamin A, are commonly used for their anti-aging and acne-fighting properties. However, they can also make your skin more sensitive to sunlight, increasing the risk of sunburn and irritation. Therefore, choosing the right sunscreen is crucial for protecting your skin while maximizing the benefits of your retinoid treatment.
Key Considerations for Sunscreen After Retinoid Use
1. Broad-Spectrum Protection: Look for a sunscreen labeled as "broad-spectrum," which means it protects against both UVA and UVB rays. UVA rays can penetrate deep into the skin and contribute to aging and skin cancer, while UVB rays are primarily responsible for sunburn.
2. SPF Rating: Choose a sunscreen with an SPF of at least 30. Higher SPF ratings provide more protection, but no sunscreen can block 100% of UV rays. Reapply every two hours, or more frequently if swimming or sweating.
3. Physical vs. Chemical Sunscreens: Physical (or mineral) sunscreens containing zinc oxide or titanium dioxide are often recommended for sensitive skin, as they sit on top of the skin and reflect UV rays. Chemical sunscreens absorb UV radiation and can sometimes cause irritation, especially on skin that is already sensitive from retinoid use. If you have sensitive skin, you might want to start with a physical sunscreen.
4. Hydrating Formulas: Since retinoids can dry out the skin, look for sunscreens that contain hydrating ingredients like hyaluronic acid, glycerin, or ceramides. These ingredients can help maintain moisture levels in the skin.
5. Non-Comedogenic: If you are prone to acne, choose a non-comedogenic sunscreen that won’t clog your pores. This is particularly important if you are using retinoids to treat acne.
6. Fragrance-Free: Fragrances can irritate sensitive skin, so opt for fragrance-free formulations to minimize the risk of irritation.
Recommended Sunscreens
Here are a few sunscreens that fit the criteria mentioned above:
- EltaMD UV Clear Broad-Spectrum SPF 46: This sunscreen is lightweight, oil-free, and contains niacinamide, which can help soothe the skin. It is particularly suitable for acne-prone and sensitive skin.
- Neutrogena Hydro Boost Water Gel Lotion SPF 30 or 50: This sunscreen is hydrating and has a gel-like texture that absorbs quickly. It contains hyaluronic acid, making it a good choice for dry skin.
- La Roche-Posay Anthelios Melt-in Milk Sunscreen SPF 60: This broad-spectrum sunscreen is suitable for sensitive skin and provides high protection without leaving a greasy residue.
- CeraVe Hydrating Mineral Sunscreen SPF 30: This mineral sunscreen is formulated with ceramides and niacinamide, providing hydration while protecting against UV rays.
Additional Tips
- Patch Test: If you are trying a new sunscreen, consider doing a patch test on a small area of your skin to check for any adverse reactions.
- Consult Your Dermatologist: Since you mentioned that you have been using a pigment treatment for a month without noticeable results, it may be beneficial to discuss this with your dermatologist during your appointment. They can provide personalized recommendations based on your skin type and concerns.
- Sun Protection Beyond Sunscreen: In addition to using sunscreen, consider wearing protective clothing, hats, and sunglasses when outdoors. Seek shade whenever possible, especially during peak sun hours.
In conclusion, protecting your skin after using retinoids is vital to prevent irritation and maximize the benefits of your treatment. By selecting the right sunscreen and following proper sun protection practices, you can help maintain healthy, radiant skin while minimizing the risk of sun damage.
