Not all serums are applied with the same frequency. This “lessens the ability of the serum to absorb effectively,” Dr. To save time, don’t try mixing a serum into your moisturizer. “Maybe you’ll use a vitamin C serum all over but then dab on for hyperpigmentation on just a few spots.” Just run any combination by your dermatologist to avoid any potential reactions. “I recommend treating different areas with different products,” Mattioli says. If you have multiple concerns, you might want to use multiple formulas. Vitamin E and C to fight daily exposure to free radicals that can age your skin.Rose water and green tea to calm irritation and reduce redness with an anti-inflammatory effect.Hyaluronic acid to boost hydration, seal in dewiness and plump skin to subtly treat fine lines.Alpha and beta hydroxy acids to gently remove dead skin cells that can clog pores, improve sun-damaged skin and minimize dullness.Most experts, the New York City aesthetician Jordana Mattioli says, consider toner to be optional: “It can be a good way to add in specific ingredients that you may not have in your other products or add another layer of skin-replenishment.” If you have the time and inclination, here are some hero ingredients to look for: Think of them as supplements - these thin liquids deliver an extra shot of nutrients, helping the other products in your regimen absorb better, while still balancing your complexion. “The original was an alcohol-based product that was used to dry up oily skin and remove any leftover dirt following cleansing,” Dr. I will use 2.1 model (512-pixel) for this test.For many, the word “toner” brings to mind stinging astringents from the ’80s. Now let’s find a good universal negative prompt. We have already touched on the importance of negative prompts in v2. Excluding NSFW images also unintentionally biases the data towards the bad and ugly. It could be a failure of the filter, or its just be the nature of the NSFW images. My second speculation is that what are deemed NSFW could also be highly aesthetic. If the data is highly curated that every single person looks way above average, prompting “woman” would be the same as prompting “beautiful woman”. Open AI trained the CLIP model with proprietary data. This affects the embeddings of the model. The first suspect is switching from Open AI’s CLIP model to OpenCLIP. Filtered out NSFW contents in training data.This is an area I can only speculate… but why not? The two changes in v2 are Why does negative prompt become more important in v2? It is as if v1.5 model does not understand these words. Adding the negative prompt ugly, deformed and disfigured may improve things but it is not as clear as in v2.1. The images comes out pretty good without any negative prompts in v1.5. Later steps are only finer adjustment to details, such as hairs covering ears.Īdding negative prompt to v1.5. The reasoning behind this is that the diffusion process is most important in the beginning steps. Since, I am using 20 sampling steps, what this means is using the as the negative prompt in steps 1 – 10, and (ear:1.9) in steps 11-20. You will get the same image as if you didn’t put anything. You can verify its uselessness by putting it in the negative prompt. Let’s pick the as the meaningless, dud negative prompt. You can use keyword switching to first use a meaningless word as negative prompt, and then switching to (ear:1.9) at a later sampling step. Now what if you really want to use a high emphasis (ear:1.9)? I don’t know what’s your problem with ears but I have a trick for you. Negative prompt could affect the diffusion process strongly. The ears are covered more by hair with in all emphasis factors but when the factor reaches 1.9, the composition of the image changed. Below are with three increasing emphasis 1.3, 1.6 and 1.9. What if we are ok with the wind but want the hair to cover the ear? Let’s add negative prompt “ear” with different emphasis factors.
