Glycolic acid can be a beneficial ingredient in skincare for some people, as it is known for its exfoliating and brightening properties. However, it is important to consider your skin type and any potential sensitivities before using glycolic acid. If you have sensitive skin or conditions such as eczema or rosacea, it may be best to avoid using glycolic acid, as it can be too harsh and potentially cause irritation. It's always a good idea to consult with a dermatologist or skincare professional to determine if glycolic acid is suitable for your skin. **

To use the ordinary glycolic acid toner, start by cleansing your face with a gentle cleanser. Then, saturate a cotton pad with the toner and gently swipe it across your face and neck, avoiding the eye area. It is recommended to use the toner in the evening, as glycolic acid can make your skin more sensitive to the sun. Follow up with your favorite moisturizer to keep your skin hydrated. It's important to start using the toner a few times a week and gradually increase the frequency as your skin gets used to it. **

For landscape photography, a camera with a high resolution sensor and wide dynamic range is ideal to capture the details and colors of the scenery. A full-frame DSLR or mirrorless camera with a wide-angle lens would be a good choice for capturing the vastness of landscapes. For street photography, a compact and discreet camera with fast autofocus and good low-light performance is preferred. A mirrorless camera with a prime lens or a high-quality compact camera would be suitable for capturing candid moments and street scenes without drawing too much attention. **

The main difference between camera settings for landscape shots and portrait photos is the aperture setting. For landscape shots, a smaller aperture (higher f-stop number) is typically used to achieve a larger depth of field and ensure that both the foreground and background are in focus. On the other hand, for portrait photos, a larger aperture (lower f-stop number) is often used to create a shallow depth of field, resulting in a blurred background that helps to emphasize the subject. Additionally, the focal length and composition may also vary between the two types of photography. **
