Topical application of vitamin A acid can be used locally, or it can be removed with a青春棒 (youth stick).

To address the concerns regarding darkened corners of the mouth and acne issues, it's essential to understand the underlying causes and potential remedies. Darkened corners of the mouth can result from various factors, including hyperpigmentation, irritation, or even certain medical conditions. Acne, on the other hand, is primarily caused by clogged pores, excess oil production, and bacteria.


Darkened Corners of the Mouth
1. Causes:
- Hyperpigmentation: This can occur due to sun exposure, hormonal changes, or even friction from habits like lip licking.

- Irritation: Certain products, such as lip balms or cosmetics, may cause allergic reactions or irritation, leading to darkening.

- Medical Conditions: Conditions like angular cheilitis, which is characterized by inflammation and cracking at the corners of the mouth, can also lead to darkening.

2. Prevention and Treatment:
- Sun Protection: Use a broad-spectrum sunscreen on your lips and the surrounding area to prevent further darkening due to UV exposure.

- Moisturization: Keeping the area well-moisturized can prevent irritation. Look for hypoallergenic lip balms that do not contain harsh chemicals.

- Avoid Irritants: Identify and avoid any products that may be causing irritation. This includes certain lipsticks or balms that contain fragrances or dyes.

- Topical Treatments: Over-the-counter creams containing ingredients like hydroquinone, kojic acid, or vitamin C can help lighten hyperpigmented areas. However, consult with a dermatologist before starting any treatment to ensure it's appropriate for your skin type.


Acne Issues
1. Causes:
- Hormonal Fluctuations: Hormones can trigger increased oil production, leading to clogged pores.

- Diet: Certain foods, particularly those high in sugar and dairy, may exacerbate acne for some individuals.

- Skin Care Products: Using comedogenic (pore-clogging) products can contribute to acne formation.

2. Prevention and Treatment:
- Cleansing Routine: Establish a gentle cleansing routine using a non-comedogenic cleanser. Avoid harsh scrubs that can irritate the skin and worsen acne.

- Topical Treatments: Products containing benzoyl peroxide, salicylic acid, or retinoids can be effective in treating acne. Again, it's advisable to consult a dermatologist for personalized recommendations.

- Dietary Adjustments: Consider reducing sugar and dairy intake, as some studies suggest these can contribute to acne in certain individuals.

- Hydration: Drink plenty of water to keep your skin hydrated and support overall skin health.


Additional Considerations
- Consult a Dermatologist: If the darkening of the corners of your mouth or persistent acne does not improve with over-the-counter treatments, it may be beneficial to consult a dermatologist. They can provide a thorough examination and recommend prescription treatments or procedures, such as chemical peels or laser therapy, for hyperpigmentation.

- Lifestyle Changes: Incorporating a balanced diet rich in antioxidants, vitamins, and minerals can support skin health. Foods high in omega-3 fatty acids, such as fish and flaxseeds, can help reduce inflammation, which may benefit both acne and skin discoloration.

In conclusion, addressing darkened corners of the mouth and acne requires a multifaceted approach that includes proper skincare, dietary considerations, and potentially professional guidance. By understanding the causes and implementing appropriate treatments, you can improve the appearance of your skin effectively.
