When to Use: After cleansing and before applying skincare products (the light can directly act on the skin without skincare products blocking it);
Avoid the "Acne Breakdown Period": If the pimple has broken open and is oozing pus, stop using it (the light may irritate the broken skin, worsening stinging and infection), and wait until the wound has scabbed over before using it again.
Frequency and Duration of Use:
Initial Period (First Week): Use once every other day, 10-15 minutes each time (allow the skin to adapt to the light and avoid over-stimulation);
Stable Period (After 1 Week): When inflammatory pimples are obvious, use once a day, 15-20 minutes each time; after the pimples have decreased, maintain 2-3 times a week.
Single session should not exceed 30 minutes (excessive exposure may cause dry skin and redness).
For best results, use with basic skincare.
LED lights are an "auxiliary tool" and must be used in conjunction with the core acne-fighting steps:
Cleansing: Use a gentle amino acid cleanser (avoid soap-based cleansers to protect the skin barrier);
Anti-inflammatory and Acne-Fighting: Use a serum/lotion containing low concentrations of salicylic acid (0.5%-1%, to unclog pores) and azelaic acid (10%-15%, antibacterial and anti-inflammatory, gentle and non-irritating) (avoid broken pimples);
Moisturizing and Repairing: Use a refreshing lotion containing ceramides, panthenol, and squalane (avoid heavy creams for acne-prone skin to prevent clogged pores);
Sunscreen: After using LED lights, skin is more sensitive to UV rays, so SPF30+, PA+++ sunscreen must be applied during the day (physical sunscreens are preferred to avoid irritation from chemical sunscreens).
IV. Contraindications and Precautions (To Avoid Potential Problems)
Absolutely Contraindicated Groups:
Pregnant women (red light may affect the fetus; there is no clear safety data);
Skin conditions with photosensitivity (e.g., lupus erythematosus, vitiligo);
Using photosensitizing medications (e.g., retinoids, tetracycline antibiotics, some whitening ingredients);
Patients with eye diseases (e.g., glaucoma, retinopathy).
Using with Caution:
Sensitive acne-prone skin: Perform a skin test behind the ear first (irradiate for 5 minutes, observe for 24 hours; if no redness or stinging occurs, then use);
Severe acne (large areas of cystic acne, nodular acne): LED lights can only be used as an adjunct; consult a doctor first (use medications as prescribed, such as isotretinoin, topical antibiotics) before using this product.
