动物皮脂质 × 防晒

综述脂质纳米系统用于经皮给药，未提及防晒。

Reviews lipid nanosystems for transdermal drug delivery, no mention of sun protection.

综述皮肤脂质在屏障功能中的作用，未提及防晒。

Reviews role of skin lipids in barrier function, no mention of sun protection.

仅描述皮肤脂质在屏障功能中的作用，未提及防晒功效。

Only describes the role of skin lipids in barrier function, no mention of sun protection.

研究皮肤脂质作为蚊子吸引剂，与防晒无关。

Study on skin lipids as mosquito attractants, not related to sun protection.

研究β-胡萝卜素对光老化的保护作用，而非皮肤脂质本身；皮肤脂质仅作为氧化产物检测的基质。

The study investigates β-carotene's photoprotective effect, not skin lipids themselves; skin lipids are only used as a matrix for detecting oxidation products.

研究表明皮肤脂质与臭氧反应产生有害产物，而非防晒。

Study shows skin lipids react with ozone to produce harmful products, not sun protection.

研究关注皮肤脂质与代谢，未涉及防晒。

Study focuses on skin lipids and metabolism, not sun protection.

研究β-胡萝卜素对UVA诱导的脂质过氧化的抑制作用，而非皮肤脂质本身的防晒功效。

The study examines β-carotene's inhibition of UVA-induced lipid peroxidation, not the photoprotective effect of skin lipids themselves.

研究皮肤脂质分布和外用化合物渗透，未涉及防晒。

Studies distribution of skin lipids and penetration of topically applied compounds, not sun protection.

研究水合作用对皮肤脂质结构的影响及大分子渗透，未涉及防晒。

Studies effect of hydration on skin lipid structure and macromolecule penetration, not sun protection.

研究胆固醇等甾醇对皮肤脂质过氧化的竞争性抑制，但未直接证明皮肤脂质具有防晒功效；结论是甾醇保护其他脂质，而非皮肤脂质整体防晒。

The study shows that sterols compete with peroxidation of other skin lipids, but does not directly demonstrate that skin lipids themselves have photoprotective effect; the conclusion is that sterols protect other lipids, not that skin lipids provide sun protection.
