Our patented blend of active peptides and botanicals that elegantly support your skin’s natural life cycle – promoting the benefits of recycling, rebuilding and replenishing the skin matrix in order to maintain a healthy glow and youthful appearance.

Peptides are small molecules comprised of several amino acid chain sequences, which like those in TriHex Technology®, can have a lipid carrier to help them more easily absorb into the skin where they can support collagen and elastin and other important functions. They are synthetically derived and are not sourced from human or animal-derived materials. ALASTIN uses well defined peptides which are predictable, therefore we can anticipate their behavior because the amino acid sequence is well known and their function has been demonstrated and proven.

Physician insights

"I typically recommend mineral based sunscreens for my sensitive skin patients because they are less likely to react to it, and this is a 100% mineral sunscreen making it great for those patients. This sunscreen has a few unique qualities about it. First of all, I’ve never felt a sunscreen like this: it’s silky and smooth, while at the same time feels lightweight and moisturizing. Another key unique property of SIlkSHIELD is the TriHex Technology®, and the more TriHex the better. Finally, SilkSHIELD has blue light protection without a tint – which is unusual, and convenient for someone who doesn’t want tinted sunscreen. It can be layered with makeup without causing that pilling effect, and is appropriate for any patient to use.”
